Galatians 1:12; Galatians 5:6; Galatians 6:15

12 For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.
6 For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
15 For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.
