Circumcision has become a flash point for the early church. Some are teaching that non-Jews have to become Jews to follow Jesus completely, including circumcision, dietary regulations, keeping weekly and annual holy days, and other Jewish practices. Since the time of Abraham, circumcision has been the mark of the covenant with Abraham’s spiritual children. Things are changing: outsiders, non-Jews, are entering into the new covenant.

Do they enter by faith alone, or is it faith plus following God’s law for Israel? Paul’s answer is clear: it is faith alone that makes Jews and outsiders right with God. So he cautions the Philippians to watch out for those who would chastise them into a false circumcision. Real followers of Jesus know that salvation doesn’t come from the blade of a knife but from His cross.
