Judaizers

Judaizers is predominantly a Christian term, derived from the Greek verb ioudaïzō (ἰουδαΐζω "live according to Jewish customs", see ioudaioi). This term is most widely known from the single use in the Greek New Testament (Galatians 2:14) where Paul publicly challenges Peter for compelling Gentile believers to "judaize", also known as the Incident at Antioch.
