Quick Summary

"Judaizers" refers to early Christians, primarily of Jewish origin, who insisted that Gentile converts to Christianity must adhere to Jewish laws and customs, such as circumcision. This led to significant debate within the early church.1

The Council of Jerusalem, around 50 CE, addressed this issue. Led by figures like St. Peter the Apostle and St. James, and with the advocacy of St. Paul the Apostle, the council decreed that Gentile Christians were not required to follow the Mosaic Law, except for abstaining from idolatry, blood, strangled animals, and sexual immorality. This decision was crucial for the expansion of Christianity beyond its Jewish roots.2

A separate group, also called Judaizers, emerged in the Russian Orthodox Church in the 15th century, emphasizing Jewish doctrines and rituals.1
