Thematic Bible: Necessity of, denied by paul

But not even Titus, who was with me, was forced to be circumcised, even though he was a Greek. However, false brothers were secretly brought in. They slipped in to spy on the freedom we have in the Messiah Jesus so that they might enslave us. But we did not give in to them for a moment, so that the truth of the gospel might always remain with you.
