Galates 5:2-6
2
Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.
3
For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
4
Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
5
For we through the Spirit wait for the hope of righteousness by faith.
6
For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
Actes 15:24
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:
Actes 16:3
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.
1 Corinthiens 9:20
And unto the Jews I became as a Jew, that I might gain the Jews; to them that are under the law, as under the law, that I might gain them that are under the law;
1 Corinthiens 9:21
To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law.
