But neither Titus, who was with me, being a Greek, was compelled to be circumcised:
Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.
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 we through the Spirit wait for the hope of righteousness by faith.
For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
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:
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 Corinthians 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 Corinthians 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.
