MAIM
This verb is used in Gal. 5:12 and in Phil. 3:2, and on both occasions with respect to the professed legalistic Christians who insisted on placing Christians from the Gentiles on the ground of the law, without which, according to them, salvation was not possible.
Paul speaks harshly against those who added to the finished work of Christ, which was received by faith alone, without anything else as an additional condition. For this reason he launches the harsh contained attacks, because the claim of the need for circumcision for salvation distorted the saving work of Christ and opened the way for much worse trends, as has been historically proven.
