The Galatians had begun their race as Christians. They were making strides of growth in Christ, yet, in the way laid an obstacle preventing further progression. Judaizing teachers had infiltrated the congregation, and were binding aspects of the Mosaic Law. The Galatians had already reverted to observing “days and months and seasons and years” (cf. 4:10), and were now being influenced to bind circumcision (v. 1-5). Paul reminded them that Christ did not instruct such conduct. The leaven of false doctrine was the influence, and those who spread it would be judged. It is worthy to note, despite the reproof from Paul, that he expressed his confidence in the Galatians’ willingness to reject sin, and follow Christ.

Paul used the reality of his persecuted state in Christ as evidence that he does not teach such doctrine. The Judaizers avoided persecution for Christ by marrying Christianity with the Old Law (cf. 6:12). If Paul preached the same message as they, he would not be suffering persecution. The height of his concern for the Galatians, and of his righteous indignation, is seen in his wish that the false teachers would step beyond circumcision and “mutilate themselves” (v. 12; NASV). This would destroy their influence they had on the Galatians. For castration was against the Law of Moses (cf. Deuteronomy 23:1), and was a virtue in Paganism.

False doctrine is abhorrent. It is a wall built by the adversary which blocks the way to heaven. It cannot be avoided by bending the path around it in tolerance. It must be addressed, and obliterated. Not a pebble from the structure can be left, for “a little leaven leavens the whole lump.” Like Paul, we must stand up against it, and show ourselves to be the opposition.
