“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.
