Galatians 5:2

For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.

And certain men which came down from Judea taught the brethren, and said, Except ye be circumcised after the manner of Moses, ye cannot be saved.

But neither Titus, who was with me, being a Greek, was compelled to be circumcised: And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage: To whom we gave place by subjection, no, not for an hour; that the truth of the gospel might continue with you.

But Israel, which followed after the law of righteousness, hath not attained to the law of righteousness. Wherefore? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumblingstone;

Him would Paul have to go forth with him; and took and circumcised him because of the Jews which were in those quarters: for they knew all that his father was a Greek. And as they went through the cities, they delivered them the decrees for to keep, that were ordained of the apostles and elders which were at Jerusalem.

And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offence of the cross ceased.

For I testify again to every man that is circumcised, that he is a debtor to do the whole law. Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.

For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.

For I bear them record that they have a zeal of God, but not according to knowledge. For they being ignorant of God’s righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.

Now I Paul myself beseech you by the meekness and gentleness of Christ, who in presence am base among you, but being absent am bold toward you:

Forasmuch as we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying, Ye must be circumcised, and keep the law: to whom we gave no such commandment:

Wherefore we would have come unto you, even I Paul, once and again; but Satan hindered us.
