Thematic Bible: Necessity of, denied by paul

And even Titus, who was with me, though a Greek, was not compelled to be circumcised: but this I did because of false brethren artfully introduced, who came to pry into our liberty which we hold in Christ Jesus, that they might bring us into bondage: to whom not even for an hour have we yielded subjection, that the truth of the gospel might abide with you.
