Philippians 3:1-6

In addition, my brothers and sisters, rejoice in the Lord. To write to you again about this is no trouble for me and is a safeguard for you. Watch out for the dogs, watch out for the evil workers, watch out for those who mutilate the flesh. For we are the circumcision, the ones who worship by the Spirit of God, boast in Christ Jesus, and do not put confidence in the flesh —  although I have reasons for confidence in the flesh. If anyone else thinks he has grounds for confidence in the flesh, I have more: circumcised the eighth day; of the nation of Israel, of the tribe of Benjamin, a Hebrew born of Hebrews; regarding the law, a Pharisee; regarding zeal, persecuting the church; regarding the righteousness that is in the law, blameless.
