Through Christianity

Frank arguably created a religious movement, now referred to as Frankism, which incorporated aspects of Christianity and Judaism. His followers, known as Frankists, engaged in sexually promiscuous rites, such as the infamous 1756 incident in Lanckoroń, Podolia (now Zarichanka, Khmelnytskyi Oblast, Ukraine), during which they were allegedly caught dancing around a half-naked woman symbolizing the Shechinah. Historical evidence indicates that Jacob Frank outwardly converted to Islam around 1757 while in the Ottoman Empire.

Later, Frankists were encouraged to convert in mass to Catholicism. The development of Frankism was one of the consequences of the messianic movement of Sabbatai Zevi. This religious mysticism followed socioeconomic changes among the Jews of Poland, Lithuania and Ruthenia.

Historical background

There were numerous outbreaks of followers of Sabbatai Zevi in Eastern Poland (now Ukraine), particularly in Podolia and Galicia, between the late 17th and the early 18th century.

In expectation of the great Messianic revolution, the members of these societies violated Jewish laws and customs. The mystical cult of the Sabbateans is believed to have included both asceticism and sensuality: some did penance for their sins, subjected themselves to self-inflicted pain, and "mourned for Zion"; others disregarded the strict rules of modesty required by Judaism, and at times were accused of being licentious, or even committing ritual incest. The Polish rabbis attempted to place the "Sabbatean heresy" in herem at the assembly at Lwów (now Lviv in Ukraine) in 1722. Still, they could not fully succeed, as it was widely popular among the nascent Jewish middle class.
