Philippians
King James Version (KJV)

“For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.”
King James Version (KJV)
3:3 For we - Christians. Are the only true circumcision - The people now in covenant with God. Who worship God in spirit - Not barely in the letter, but with the spiritual worship of inward holiness. And glory in Christ Jesus - As the only cause of all our blessings. And have no confidence in the flesh - In any outward advantage or prerogative.
Php 3:3 We are the circumcision. See notes Ro 2:29 4:12. The true circumcision is not in the flesh, but of the heart in the Spirit.
