Galatians 6:12-16

As many as desire to make a fair shew in the flesh, they constrain you to be circumcised; only lest they should suffer persecution for the cross of Christ.

For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh.

But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.

For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.

And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God.
