Philippians 3:3

For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.

'We are the (real) circumcision (Romans 2:25).

Worship God in the Spirit. So C, Vulgate. But 'Aleph (') A B G read 'worship by the Spirit of God.' The Spirit is the influence whereby our religious service [ latreia (G2999)] is rendered (John 4:23). Legal worship consisted in outward acts, restricted to certain times and places. Christian worship is spiritual, flowing from the inworking Holy Spirit; not restricted to isolated acts, but embracing the whole life (Romans 12:1). In the former, men trusted in something human, whether descent from the theocratic nation, or the righteousness of the law, or mortification of "the flesh" (Romans 1:9).

Rejoice (make our boast) in Christ Jesus - not in the law.

Have no confidence in the flesh - the outward and earthly, but in the Spirit.
