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.
