Christianity in the 21st century

Eastern Orthodoxy

Pan-Orthodox Council

The Pan-Orthodox Council, officially styled the Holy and Great Synod, opened at Crete, on 19 June 2016. The 10 Churches that sent representatives to Crete were the Ecumenical Patriarchate of Constantinople and the Orthodox Churches of Alexandria, Jerusalem, Serbia, Romania, Greece, Poland, Albania, Cyprus and the Czech Lands and Slovakia. Of the 14 national Orthodox churches, four did not attend the event, including the Russian Orthodox Church, the Georgian and Bulgarian Orthodox Churches, as well as the Orthodox Church of Antioch. The Council concluded on 26 June 2016, the Sunday of All Saints, with a Patriarchal Concelebration.

2018 Moscow–Constantinople schism

On 11 October 2018, the Ecumenical Patriarchate of Constantinople announced it would grant autocephaly to the "Church of Ukraine" thus separating it from the canonical jurisdiction of the Moscow Patriarchate. Four days later, the Moscow Patriarchate broke the communion with the Ecumenical Patriarchate of Constantinople over the latter's endorsement of the Ukrainian Orthodox church's autocephaly. The decision was made following a meeting of the Russian Holy Synod in Minsk, the capital of Belarus. Metropolitan Hilarion announced that the Moscow Patriarchate had taken the decision to "rupture full communion with the Constantinople Patriarchate", meaning that priests from the two churches will not be able to serve together while worshippers of one cannot take communion in the other.

Two months later, on 15 December 2018, a unification council was convoked by the Ecumenical Patriarchate of Constantinople at St Sophia's Cathedral in Kyiv, during which the Kyiv Patriarchate, the Ukrainian Autocephalous Orthodox Church and parts of the Ukrainian Orthodox Church (Moscow Patriarchate) were united into a single church: the Ukrainian Orthodox Church. Metropolitan Epiphanius was elected the first Metropolitan of Kyiv and All Ukraine of the newly unified Ukrainian church. Patriarch Kirill of Moscow denounced the new Ukrainian Church as "a union of two schismatic groups."

On 5 January 2019, Ecumenical Patriarch Bartholomew signed a tomos officially granting autocephaly to the Ukrainian Orthodox Church. The tomos was signed at St. George's Cathedral in the presence of Petro Poroshenko, the President of Ukraine, and was presented to Metropolitan Epiphanius to be brought to Kyiv in time for Christmas, the first liturgy celebrated by the united Ukrainian Orthodox Church.

On 30 May 2019, Vladimir Legoyda, head of the Synodal Department for Church, Society and Media Relations of the ROC, said the ROC was aware of the efforts of the Church of Cyprus primate, Chrysostomos II, and added that "to some extent [Chrysostomos'] actions can be considered in line with the ROC proposal (...) He has consistently held talks with representatives from various local Churches, telling of the need to resolve the problem" Legoyda also said the ROC "has repeatedly stressed the desire and the need for a pan-Orthodox decision on this issue because it cannot be resolved unilaterally"

On 12 October 2019, the Orthodox Church of Greece, headed by the Archbishop Ieronymos II recognized the Autocephaly of the Orthodox Church of Ukraine, stating that "the Ecumenical Patriarchate of Constantinople has the right to granting autocephalies"

On 8 November 2019, the Patriarchate of Alexandria, ranked second in the diptych of the Eastern Orthodox Churches of the world, officially announced it had recognized the Orthodox Church of Ukraine, and Patriarch Theodore II of Alexandria formally recognised the Autocephaly granted by the Ecumenical Patriarchate of Constantinople to the Orthodox Church of Ukraine earlier that year.

On 24 October 2020, the primate of the Church of Cyprus, Archbishop Chrysostomos II, commemorated Epiphanius of Ukraine during the Divine Liturgy, thus recognising the Orthodox Church of Ukraine.

Hagia Sophia and Chora Church

In early July 2020, the Turkish Council of State annulled the Cabinet's 1934 decision to establish the museum, revoking the monument's status, and a subsequent decree by Turkish president Recep Tayyip Erdoğan ordered the reclassification of Hagia Sophia as a mosque. The 1934 decree was ruled to be unlawful under both Ottoman and Turkish law as Hagia Sophia's waqf, endowed by Sultan Mehmed, had designated the site a mosque; proponents of the decision argued the Hagia Sophia was the personal property of the sultan. This redesignation is controversial, invoking condemnation from the Turkish opposition, Ecumenical Patriarch Bartholomew I of Constantinople, UNESCO, the World Council of Churches, the International Association of Byzantine Studies, and many international leaders.

In November 2019, the Turkish Council of State, Turkey's highest administrative court, ordered that Chora Church was to be reconverted to a mosque. In August 2020, its status changed to a mosque. The move to convert Chora Church into a mosque was condemned by the Greek Foreign Ministry and Christians. This caused a sharp rebuke by Turkey.

Archdiocese of Ohrid

The President of North Macedonia expressed his hope and expectation for a final settlement of the administrative status of his country's church in the near future through the granting of an Autocephaly Tomos by the Ecumenical Patriarchate, stressing that the completion of the autocephaly of the church of North Macedonia is a top national interest. The Holy and Sacred Synod of Constantinople convened Monday May 9, 2022, under the chairmanship of Ecumenical Patriarch Bartholomew, and discussed extensively the ecclesiastical matter of Skopje. Having assessed in its final stage the petition of appeal of that Church to the Mother Church, along with the repeated pleas of the State of North Macedonia, the Ecumenical Patriarchate announced that it welcomes in Eucharistic communion "the hierarchy, clergy, and people of this Church under Archbishop Stefan." It makes clear that it excludes the term "Macedonian" and any other derivative of the word "Macedonia", and recognizes the name of the Church as "Ohrid". Ecumenical Patriarch Bartholomew clarified that it was up to the Church of Serbia to settle the administrative issues between it and the Church in North Macedonia. He promises to continue to be interested in the progress and stability of the Ohrid ecclesiastical entity.

The Serbian Orthodox Church accepted the request of the Church of North Macedonia to acquire autocephaly. On May 24, 2022, the Patriarch of Serbia and the Archbishop of Ohrid co-officiated the Divine Liturgy for the feast of Saints Cyril and Methodius at the Cathedral of Saint Clement of Ohrid in Skopje.

Protestantism

Megachurches

Postmodern Christianity has influenced the emerging church movement, with proponents challenging the mainstream Christianity on issues such as: institutional structures, systematic theology, propositional teaching methods, a perceived preoccupation with buildings, an attractional understanding of mission, professional clergy, and a perceived preoccupation with the political process and unhelpful jargon ("Christian-ese"). Globally, megachurches are a significant development in Protestant Christianity. In the United States, the phenomenon has more than quadrupled in the past two decades. It has since spread worldwide. In 2007, five of the ten largest Protestant churches were in South Korea. The largest megachurch in the United States is Lakewood Church in Houston, Texas with more than 40,000 members every weekend and the current largest megachurch in the world is South Korea's Yoido Full Gospel Church, an Assemblies of God church, with more than 830,000 members as of 2007.

Mark Driscoll, a leader in the emerging church movement, had more than 12,000 followers at Mars Hill Church in Seattle, Washington before controversy led to Driscoll's resignation in 2014 and Mars Hill's dissolution. Like other churches in the emerging church movement, Mars Hill combined alternative worship with Calvinist theology. In 2015, not without controversy, a video featuring Driscoll was featured at a Hillsong Church conference in Sydney, Australia. Hillsong Church is a megachurch, founded in 1983, that has grown to over 100,000 followers. Their 2013 song "Oceans (Where Feet May Fail)" was released and spent 61 weeks atop the Billboard Hot Christian Songs chart, longer than any other song.

Some megachurches, including Lakewood and Yoido Full, teach prosperity theology, a controversial doctrine seen as a heresy by most Christians. In 2007, U.S. Senator Chuck Grassley opened a probe into the finances of six televangelism ministries that promoted prosperity theology: Kenneth Copeland Ministries, Creflo Dollar Ministries, Benny Hinn Ministries, Bishop Eddie Long Ministries, Joyce Meyer Ministries, and Paula White Ministries. In January 2011, Grassley concluded his investigation stating that he believed self-regulation by religious organizations was preferable to government action. Only the ministries led by Meyer and Hinn cooperated with Grassley's investigation. The inauguration of Donald Trump as the 45th President of the United States in 2017 featured prayers from two preachers known for advocating prosperity theology. Paula White, one of Trump's spiritual advisers, gave the invocation.

The heterodox Shincheonji megachurch was the source of the COVID-19 pandemic in South Korea, with most cases in South Korea being tied to the spread of the SARS-CoV-2 virus within the megachurch. On 1 March 2020, Seoul mayor Park Won-soon announced that the Seoul City Government had made a criminal complaint about the church's pastor Lee Man-hee, whom Shincheonji adherents believed to be the messiah, asking for an investigation into him and twelve others connected to the sect on charges of murder by negligence and violations of the Disease Control Act, citing their negligence in preventing an outbreak among their congregants and their refusal to cooperate with the government throughout the crisis.

Anglican Communion

One month prior to the Lambeth Conference, the ten-yearly gathering of Anglican Communion bishops, a seven-day conference of conservative Anglican bishops and leaders held in Jerusalem from 22 to 29 June 2008 to address the growing controversy of the divisions in the Anglican Communion, the rise of secularism, as well as concerns with HIV/AIDS and poverty. As a result of the conference, the Jerusalem Declaration was issued and the Fellowship of Confessing Anglicans was created. The conference participants also called for the creation of the Anglican Church in North America (ANCA), as an alternative to the Episcopal Church in the United States and the Anglican Church of Canada, and declared that recognition by the Archbishop of Canterbury is not necessary to Anglican identity. Follow-up conferences have been held every five years since 2008.

The conventions of four dioceses of the Episcopal Church voted in 2007 and 2008 to leave that church and to join the Anglican Church of the Southern Cone of America. Twelve other jurisdictions, serving an estimated 100,000 persons at that time, formed the ACNA on December 3–4, 2008. The ACNA is seeking official recognition as a province within the Anglican Communion. The Anglican Church of Nigeria declared itself in communion with the new church in March 2009 and the Fellowship of Confessing Anglicans recognized it as well. In June 2009, the Anglican Church of Uganda also declared itself in full communion with ACNA, and the Anglican Church of Sudan followed suit in December 2011.

Two of the major events which contributed to the Anglican realignment were the 2002 decision of the Diocese of New Westminster in Canada to authorise a rite of blessing for same-sex unions, and the nomination of two openly gay priests in 2003 to become bishops. Jeffrey John, an openly gay priest with a long-time partner, was appointed to be the next Bishop of Reading in the Church of England and the General Convention of the Episcopal Church ratified the election of Gene Robinson, an openly gay non-celibate man, as Bishop of New Hampshire. Jeffrey John ultimately declined the appointment due to pressure.

United Methodist Church

Like many other mainline Protestant denominations in the United States, the United Methodist Church has experienced significant membership losses in recent decades. By the opening of the 2008 General Conference, total UMC membership was estimated at 11.4 million, with about 7.9 million in the US and 3.5 million overseas. Significantly, about 20 percent of the conference delegates were from Africa, with Filipinos and Europeans making up another 10 percent. During the conference, the delegates voted to finalize the induction of the Methodist Church of the Ivory Coast and its 700,000 members into the denomination. One Congolese bishop has estimated that typical Sunday attendance of the UMC is higher in his country than in the entire United States.

Given current trends in the UMC, with overseas churches growing, especially in Africa, and US churches collectively losing about 1,000 members a week, American influence on the UMC is declining. In February 2019, a Special Session of the General Conference of the United Methodist Church was held in St. Louis, Missouri, to examine church teachings on human sexuality. While most American delegates at the General Conference supported the One Church Plan, a resolution that would have made the UMC open and affirming on LGBT issues, allowing individual conferences to allow same-sex marriage and openly gay clergy, the resolution failed. In its place, the Traditional Plan, opposed by most American delegates but supported by the African delegates, was passed by the conference. The Traditional Plan reaffirms traditional teachings on sexuality, penalizes UMC clergy who conduct same-sex marriages or ordain openly gay clergy beginning in 2020.

Some conferences have allowed both same-sex marriage and openly gay clergy for years. One conference in the American Southwest has a lesbian bishop, Karen Oliveto. It is unknown how these clergy will be affected by the rule change. A similar General Conference decision in 1984 led to the early retirement of some openly gay clergy, including Paul Abels. Many progressive clergy have vowed to ignore the new rules if and when they come into effect, and many clergy and congregations are openly contemplating the idea of a schism within the United Methodist Church.

With the Traditional Plan in place, the UMC increasingly saw schism as inevitable and so plans were drawn up to be voted upon at 2020 General Conference. However, due to the coronavirus pandemic, the General Conference was delayed to 2021.

Internet church

The concept of an internet church, utilizing livestreams of services on websites such as YouTube and Zoom, became widespread in the early 2020s. This method of church attendance gained popularity as a result of the COVID-19 pandemic, when in-person church services were interrupted.

Oriental Orthodoxy

Coptic Church

In April 2006, one person was killed and twelve injured in simultaneous knife attacks on three Coptic churches in Alexandria.

In November 2008, several thousand Muslims attacked a Coptic church in a suburb of Cairo on the day of its inauguration, forcing 800 Coptic Christians to barricade themselves in.

In April 2009, two Christian men were shot dead and another was injured by Muslim men after an Easter vigil in the south of Egypt.

On 18 September 2009, a Muslim man named Osama Araban beheaded a Coptic Christian man in the village of Bagour, and injured 2 others in 2 different villages. He was arrested the following day.

On the eve of 7 January 2010, as worshippers were leaving the Mar-Yuhanna (St. John) church in Nag Hammadi after Eastern Christmas Mass(which finishes around midnight), three Muslim men in a car opened fire, killing 8 Christians and injuring another 10.

On New Year's Day 2011, just 20 minutes after midnight as Christians were leaving a Coptic Orthodox Church in the city of Alexandria after a New Year's Eve service a car bomb exploded in front of the Church killing more than 23 and injuring more than 75.

In Tahrir Square, Cairo, on Wednesday 2 February 2011, Coptic Christians joined hands to provide a protective cordon around their Muslim neighbors during salat (prayers) in the midst of the 2011 Egyptian Revolution.

On 7 May 2011, an armed group of Islamists, including Salafists, attacked and set fire to two churches including Saint Menas Coptic Orthodox Christian Church and the Coptic Church of the Holy Virgin, in Cairo. The attacks resulted in the deaths of 12 people and more than 230 wounded. It is reported that the events were triggered by a mixed marriage between a Christian woman and a Muslim man.

On 17 March 2012, the Coptic Orthodox Pope, Shenouda III died, leaving many Copts mourning and worrying as tensions rose with Muslims. Shenouda III had constantly met with Muslim leaders in order to create peace. Many were worried about Muslims controlling Egypt, as the Muslim Brotherhood had won 70% of the parliamentary elections. Tawadros II was elected Pope on 4 November 2012.

In February 2015, twenty-one Coptic Christians were kidnapped and beheaded in Libya by ISIS insurgents. Six days later, they were canonized as martyrs by Pope Tawadros II.

In January 2017, following twin terrorist attacks that killed at least 27 Coptic Egyptians at St. Peter and St. Paul's Church in Cairo in December 2016, the President of Egypt Abdel Fattah el-Sisi commissioned the construction of the country's largest mosque and church in the new administrative capital to become symbols of coexistence and national unity. For decades, the building of churches in Egypt was restricted to avoid offending Islam. The Cathedral of the Nativity in Cairo was inaugurated on 6 January 2019 by President el-Sisi and Pope Tawadros II. On the same day of the inauguration, Divine Liturgy was celebrated in the chapel of the cathedral with the participation of some 3,000 people that included representatives from all over the country.

Armenian Church

The construction of the Holy Mother of God Cathedral in Stepanakert, Nagorno-Karabakh began in 2006 and was completed in 2019. The cathedral was demolished in April 2026 by Azerbaijan.

In October 2013 Father Asoghik Karapetyan, the director of the Museum of the Mother See of Holy Etchmiadzin, stated on television that an atheist Armenian is not a "true Armenian". A spokesperson for the Armenian Apostolic Church stated that it is his personal view. The statement received considerable criticism, though Asoghik did not retract his statement. In an editorial in the liberal Aravot daily Aram Abrahamyan suggested that religious identity should not be equated with national (ethnic) identity and it is up to every individual to decide whether they are Armenian or not, regardless of religion. According to a 2018 survey by the Pew Research Center, in Armenia 82% of respondents say it is very or somewhat important to be a Christian to be truly Armenian.

On 24 April 2015, the Armenian Apostolic Church canonized all of the victims of the Armenian genocide as martyrs, which began a hundred years prior to the following day on 24 April 1915; this service is believed to be the largest canonization service in history. It was the first canonization by the Armenian Apostolic Church in four hundred years.

On 26 September 2017, a deaconess was consecrated in the Tehran Diocese of the Armenian Apostolic Church, the first Armenian deaconess in a hundred years.

On 3 October 2019, Turkish newspaper Hürriyet reported on a 2012 lawsuit advancing through Turkish courts; the lawsuit was filed by Patriarch Nourhan Manougian of Jerusalem in an attempt to reclaim patriarchate property confiscated by the Turkish government during the Armenian genocide in 1915. According to Patriarch Manougian, the "Armenian Patriarchate in Jerusalem owned around 1,200 properties in Istanbul alone" prior to the genocide. The court had originally dismissed the case in 2012, despite the patriarchate winning an appeal, but a decision from the Constitutional Court of Turkey ruled on 12 September 2019 that the previous court had violated the rights of the patriarchate.

Amidst the Second Nagorno-Karabakh War, on 8 October 2020, the mother church of Artsakhtsi Christians Ghazanchetsots Cathedral in Shushi was bombed by the Azerbaijani Armed Forces. Archbishop Pargev Martirosyan of Artsakh compared the shelling with the actions of Islamic State of Iraq and the Levant, saying "They are bombarding our spiritual values, when we are restoring and preserving mosques". Another priest at the cathedral said "I feel the pain that the walls of our beautiful cathedral are destroyed. I feel the pain that today the world does not react to what's happening here and that our boys are dying defending our Motherland".

Ethiopian Church

Patriarch Abune Paulos died on 16 August 2012, followed four days later by Ethiopian Prime Minister Meles Zenawi. On 28 February 2013, a college of electors assembled in Addis Ababa and elected Abune Mathias to be the 6th Patriarch of the Ethiopian Orthodox Church.

On 25 July 2018, delegates from the Patriarchate in Addis Ababa, Ethiopia and those in the United States, declared reunification in Washington, D.C., with the assistance of Ethiopian Prime Minister Abiy Ahmed. Declaring the end of a 26 year old schism, which began in 1991 when the Ethiopian People's Revolutionary Democratic Front seized power in Ethiopia and exiled the patriarch, the Church announced that it now acknowledges two patriarchs: Abune Merkorios, the 4th Patriarch of Ethiopia, and Abune Mathias, the 6th Patriarch of Ethiopia.

Eritrean Church

The first Patriarch of the newly independent Eritrean Orthodox Tewahedo Church, Abune Phillipos, died in 2002 and was succeeded by Abune Yacob. The reign of Abune Yacob as Patriarch of Eritrea was very brief as he died not long after his enthronement, and he was succeeded by Abune Antonios as the 3rd Patriarch of Eritrea. Abune Antonios was elected on 5 March 2004, and enthroned as the third Patriarch of Eritrea on 24 April 2004. Coptic Pope Shenouda III of Alexandria presided at the ceremony in Asmara, together with the Holy Synod of the Eritrean Orthodox Church and a Coptic Orthodox Church delegation.

In August 2005, Abune Antonios, the Patriarch of the Eritrean Orthodox Tewahedo Church, was confined to a strictly ceremonial role. In a letter dated 13 January 2006, Patriarch Abune Antonios was informed that following several sessions of the church's Holy Synod, he had been formally deposed. In a written response that was widely published, the Patriarch rejected the grounds of his dismissal, questioned the legitimacy of the synod, and excommunicated two signatories to the 13 January 2006 letter, including Yoftahe Dimetros, whom the Patriarch identified as being responsible for the church's recent upheavals. Patriarch Antonios also appealed his case to the Council of the Monasteries of the Eritrean Orthodox Church and to the Coptic Orthodox Church of Alexandria. Abune Antonios was deposed by the Eritrean Holy Synod supposedly under pressure from the Eritrean government and he remains under house arrest. Abuna Antonios was replaced by Abune Dioskoros as the 4th Patriarch of Eritrea. Many believe that Abune Antonios was wrongly deposed and still consider him Patriarch. Many Eritrean Orthodox followers disagree with the Eritrean government making decisions in religious matters. The ruling Patriarch Abune Dioskoros died on 21 December 2015. His seat remained vacant until 2021 when he was succeeded by Abune Qerlos.

Assyrian Church

After the fall of Mosul, the Islamic State of Iraq and the Levant demanded that Assyrian Christians living in the city convert to Islam, pay tribute, or face execution, by 19 July 2014. Al-Baghdadi further noted that Christians who do not agree to follow those terms must "leave the borders of the Islamic Caliphate" within a specified deadline. This resulted in a complete Assyrian Christian exodus from Mosul, marking the end of 1,600 years of continuous Christian presence. A church mass was not held in Mosul for the first time in 1,800 years. On 9 July 2017, Iraqi Prime Minister Haider Al-Abadi arrived in preparation to announce the full liberation of Mosul and reclaim the city after three years of ISIL control.

Ecumenical dialogue

Catholic–Armenian

On 18 February 2001, Pope John Paul II during his Angelus address commemorated the 1,700th anniversary of the baptism of the Armenian people and referred to St. Gregory of Narek (Armenian: Գրիգոր Նարեկացի) as "the great doctor of the Armenian Church." In September 2001, John Paul II traveled to Armenia and participated in an ecumenical liturgy at the newly consecrated Cathedral of St. Gregory the Illuminator in Yerevan.

On 12 April 2015, on Divine Mercy Sunday, during a Mass for the centennial of the Armenian genocide at St. Peter's Basilica, Pope Francis officially proclaimed St. Gregory of Narek as a Doctor of the Church in attendance of Armenian President Serzh Sargsyan, Catholicos of All Armenians Karekin II, Catholicos of Cilicia Aram I, and Armenian Catholic Patriarch Nerses Bedros XIX Tarmouni. He became the 36th and the first Armenian Doctor of the Church. He is also the only Doctor "who was not in communion with the Catholic Church during his lifetime."

Cathedral of the Holy Martyrs (Armenian: Սրբոց Նահատակաց եկեղեցի) in Gyumri, Armenia, the cathedral for the Armenian Catholic Ordinariate for Armenia, Georgia, Russia, and Eastern Europe was consecrated by Krikor Bedros XX Gabroyan, Catholicos-Patriarch of the Armenian Catholic Church, and Cardinal Leonardo Sandri, Prefect of the Congregation for the Oriental Churches, on 24 September 2015. The ceremony was held as part of the commemoration of the centennial of the Armenian Genocide. The cathedral is named "Holy Martyrs" in memory of victims of the Armenian Genocide, as the Armenian Apostolic Church canonized them as martyrs. On 25 June 2016, Pope Francis, accompanied by Catholicos Karekin II, visited the cathedral.

On 26 June 2016, Catholicos Karekin II and Pope Francis signed a joint declaration on the family. It stated that the secularization of society and its "alienation from the spiritual and divine" are damaging to the family, and affirmed that the Catholic and Armenian Apostolic churches share a marriage–based view of the family. The declaration also took note of various positive steps taken towards unity between the two leaders' churches, and "acknowledged the successful 'new phase' in relations" between them. It also lamented "immense tragedy" of the widespread persecution of Christians in the Middle East; the Pope and the Catholicos prayed "for a change of heart in all those who commit such crimes and those who are in a position to stop the violence".

On 5 April 2018, a two-meter-high bronze statue of St. Gregory of Narek, erected by Davit Yerevantsi, was unveiled at the Vatican Gardens by Mikael Minasyan, Armenia's Ambassador to the Holy See. The inaugural ceremony was attended by Pope Francis, Armenian President Serzh Sargsyan, Armenian Apostolic catholicoi Karekin II and Aram I. In September 2018, Archbishop Khajag Barsamian was appointed in early September as the first-ever representative of the Apostolic Armenian Church to the Holy See.

Coptic–Greek

In the summer of 2001, the Coptic Orthodox Church of Alexandria and Greek Orthodox Patriarchate of Alexandria agreed to mutually recognize baptisms performed in each other's churches, making re-baptisms unnecessary, and to recognize the sacrament of marriage as celebrated by the other.

Catholic–Anglican

Pope John Paul II officially called off all future talks between the Catholic Church and the Anglican Communion upon the consecration of Gene Robinson as a bishop in 2003. In conversation with the Anglican Bishop of Gibraltar, Cardinal Walter Kasper, president of the Pontifical Council for Promoting Christian Unity, warned that if the Church of England was to ordain women as bishops, as the Episcopal Church had already done, then it could destroy any chance of reuniting the Catholic and Anglican churches. In December 2014, Libby Lane was announced as the first woman to become a bishop in the Church of England. She was consecrated as a bishop in January 2015. In July 2015, Rachel Treweek was the first woman to become a diocesan bishop in the Church of England when she became the Bishop of Gloucester. She and Sarah Mullally, Bishop of Crediton, were the first women to be ordained as bishops at Canterbury Cathedral. Treweek later made headlines by calling for gender-inclusive language, saying that "God is not to be seen as male. God is God."

In late 2009, in response to requests from various groups of Anglicans around the world who were dissatisfied with liberalizing movements within the Anglican Communion, Pope Benedict XVI issued the apostolic constitution Anglicanorum Coetibus. This document invites groups of traditionalist Anglicans to form what are termed "Anglican ordinariates" or "personal ordinariates" under the ecclesiastical jurisdiction of the Catholic Church, while preserving elements of the liturgical, musical, theological and other aspects of their Anglican patrimony. Under these terms, regional groupings of Anglican Catholics may apply for reception by the Holy See under the jurisdiction of an "ordinary" (i.e. a bishop or priest) appointed by Rome to oversee the community. While being in a country or region which is part of the Latin Church of the Catholic Church, these ordinaries will nonetheless retain aspects of the Anglican patrimony, such as married priests and traditional English choral music and liturgy.

As of 2013, marrying a Catholic no longer disqualifies a person from succeeding to the British Crown. The explanation published when the bill had been introduced mentioned that those who had lost their places in the line of succession by marrying a Catholic would regain their places, but that those "with a realistic prospect of succeeding to the Throne" would not be affected. The first person in the new line of succession to be affected by this change when it came into effect was George Windsor, Earl of St Andrews, who had married a Catholic in 1988, and was restored to the line of succession in 34th place, after his father the Duke of Kent, although his Catholic children remain excluded. The provision of the Act of Settlement requiring the monarch to be a Protestant continues, as the monarch remains the Supreme Governor of the Church of England.

On 13 October 2019, Pope Francis canonized Saint John Henry Newman, a London-born priest who led the Oxford Movement in the Church of England before converting to Catholicism and becoming an Oratorian Father and eventually the Cardinal-Deacon of San Giorgio in Velabro. Newman is the first Englishman who has lived since the 17th century to be officially recognised as a saint by the Catholic Church. In attendance at the canonization ceremony in St. Peter Square was Charles, Prince of Wales, who in 2022 would become king and Supreme Governor of the Church of England.

Catholic–Orthodox

In June 2004, the Ecumenical Patriarch Bartholomew I's visit to Rome afforded a meeting with Pope John Paul II, for conversations with the Pontifical Council for Promoting Christian Unity and for taking part in the celebration for the feast day in St. Peter's Basilica. Some of the bones of Saints Gregory the Theologian and John Chrysostom, which were looted from Constantinople by the Fourth Crusade in 1204, were returned to the Church of St George, Istanbul by Pope John Paul II.

The Ravenna Document in 2007 re-stated the notion that the Bishop of Rome is indeed the first (Greek: πρώτος, romanized: protos) among the patriarchs, although future discussions are to be held on the concrete ecclesiological exercise of papal primacy.

Patriarch Bartholomew attended the papal inauguration of Pope Francis on 19 March 2013, paving the way for better Catholic–Orthodox relations. It was the first time that the spiritual head of Eastern Orthodox Christians had attended a papal inauguration since the Great Schism in 1054. After, he invited Pope Francis to travel with him to the Holy Land in 2014 to mark the fiftieth anniversary of the embrace between Patriarch Athenagoras and Pope Paul VI.

On 12 February 2016, Pope Francis and Patriarch Kirill of Moscow met in a VIP room at José Martí International Airport near Havana, Cuba. Francis arrived at 2 pm local time, and the two leaders embraced and kissed. A 2-hour private meeting was followed by the signing of a joint declaration, which had been prepared in advance. The 30-point declaration contained a joint call by the two church primates for an end to the persecution of Christians in the Middle East and to wars in the region, expressing their hope that the meeting might contribute to the re-establishment of Christian unity between the two churches. A range of other issues are mentioned in the declaration, including atheism, secularism, consumerism, migrants and refugees, the importance of marriage and the family, and concerns relating to abortion and euthanasia.

On 3 July 2019, it was revealed that during a Vatican meeting with Orthodox Archbishop Job of Telmessos, who represented the Ecumenical Patriarch Bartholomew of Constantinople, during the feast of Sts. Peter and Paul on 29 June 2019, Pope Francis stated that unity rather than leveling differences should be the goal between the Catholic and Orthodox Churches. Pope Francis also gave Bartholomew nine bone fragments which were believed to have belonged to Saint Peter and which were displayed at a public Mass which was held in the Vatican in November 2013 to celebrate the Year of Faith. Despite holding a "cordial" meeting with Russian President Vladimir Putin, with whom the Pope has had a history of good relations, on 4 July 2019, tensions between the Vatican and Russian Orthodox churches still remained, with Pope Francis stating that it is unlikely that he will visit Russia unless Putin agrees to not include the Russian Orthodox Church in the visit. Putin also stated to the Pope that he would not invite the Pope to Russia without this condition. Pope Francis also hinted that was willing to support the concerns of Ukrainian Greek Catholic Church, which has expressed opposition to both Putin's intervention in Ukraine and the Vatican's current relationship with Putin. At the beginning of a two-day Vatican meeting with Ukrainian Greek-Catholic leaders on 5 July 2019, Pope Francis hinted that he supported the Church's concerns in Ukraine and called for greater humanitarian aid to Ukraine.

On 12 November 2019, Patriarch Bartholomew, the Abbot of Xenophontos and a hieromonk from Pantokratoros Monastery on Mount Athos participated in a Vespers service at the Abbey of Notre-Dame de Saint-Rémy, a Trappist Catholic monastery. Upon returning with the abbots to Mount Athos, Bartholomew gave a speech at Pantokratoros Monastery declaring that union with the Catholic Church is inevitable as no theological differences exist between the churches and only historical differences have kept the two churches from union.

Catholic–Lutheran

In 2016, on the 499th anniversary of the start of the Protestant Reformation, Pope Francis travelled to Sweden (where the Lutheran Church is the national Church) to commemorate the Reformation at Lund Cathedral, which serves as the seat for the Lutheran Bishop of Lund. An official press release from the Holy See stated:

The Lutheran World Federation (LWF) and Roman Catholic Church joint event will highlight the 50 years of continuous ecumenical dialogue between Catholics and Lutherans and the joint gifts of this collaboration. The Catholic-Lutheran commemoration of 500 years of the Reformation is structured around the themes of thanksgiving, repentance and commitment to common witness. The aim is to express the gifts of the Reformation and ask forgiveness for division perpetuated by Christians from the two traditions.

An ecumenical service was presided over by Munib Younan, the president of the Lutheran World Federation, Martin Junge, the General Secretary of the LWF, as well as Pope Francis. Representatives from the Anglican Communion, Baptist World Alliance, Eastern Orthodox Church, and Salvation Army also participated in the predominantly Catholic and Lutheran event. Pope Francis, in a joint statement with Munib Younan, stated that "With gratitude we acknowledge that the Reformation helped give a greater centrality to sacred Scripture in the Church's life".

Catholic–Coptic

On 28 April 2017, Pope Francis and Coptic Pope Tawadros ll agreed that they would not require re-baptism for Catholics who seek to join the Coptic Orthodox Church, and vice versa. The Catholic Church baptizes by affusion (pouring) and the Coptic Orthodox Church baptizes by immersion, but this declaration means that the two churches recognize each other's baptisms as a valid sacrament.
