Judaizers

Judaizers is a term for Christians who insist that their co-religionists should follow the Law of Moses. This term is most widely known from its single use in the Greek New Testament (Galatians 2:14) where Paul publicly challenges Peter for compelling gentile converts to Early Christianity to "judaize", also known as the Incident at Antioch.

This term includes groups who claim the necessity of continued obedience to the Law of Moses found in the first five books of the Christian Old Testament. Members of such groups, notably the Seventh-day Adventist Church, dispute the use of the term because "Judaizers" is typically used as a pejorative.

Most Christians believe that much of the Old Covenant has been superseded, while some modern Protestants believe it has been completely abrogated and replaced with the Law of Christ. The Christian debate over Judaizing began in the lifetime of the apostles, notably at the Council of Jerusalem and the Incident at Antioch. It has been carried on parallel to continuing debates about Paul the Apostle and Judaism, Protestant views of the Ten Commandments, and Christian ethics.
