Jerome, who understood not this passage, nor the whole epistle for that matter, excuses Peter’s action on the ground “that it was done in ignorance.” But Peter offended by giving the impression that he was indorsing the Law. By his example he encouraged Gentiles and Jews to forsake the truth of the Gospel. If Paul had not reproved him, there would have been a sliding back of Christians into the Jewish religion, and a return to the burdens of the Law. It is surprising that Peter, excellent apostle that he was, should have been guilty of such vacillation. In a former council at Jerusalem he practically stood alone in defense of the truth that salvation is by faith, without the Law. Peter at that time valiantly defended the liberty of the Gospel. But now by abstaining from meats forbidden in the Law, he went against his better judgment. You have no idea what danger there is in customs and ceremonies. They so easily tend to error in works. VERSE 13. And the other Jews dissembled likewise with him; insomuch that Barnabas also was carried away with their dissimulation. It is marvelous how God preserved the Church by one single person. Paul alone stood up for the truth, for Barnabas, his companion, was lost to him, and Peter was against him. Sometimes one lone person can do more in a conference than the whole assembly. I mention this to urge all to learn how properly to differentiate between the Law and the Gospel, in order to avoid dissembling. When it come to the article of justification we must not yield, if we want to retain the truth of the Gospel. When the conscience is disturbed, do not seek advice from reason or from the Law, but rest your conscience in the grace of God and in His Word, and proceed as if you had never heard of the Law. The Law has its place and its own good time. While Moses was in the mountain where he talked with God face to face, he had no law, he made no law, he administered no law. But when he came down from the mountain, he was a lawgiver. The conscience must be kept above the Law, the body under the Law. Paul reproved Peter for no trifle, but for the chief article of Christian doctrine, which Peter’s hypocrisy had endangered. For Barnabas and other Jews followed Peter’s example. It is surprising that such good men as Peter, Barnabas, and others should fall into unexpected error, especially in a matter which they knew so well. To trust in our own strength, our own goodness, our own wisdom, is a perilous thing. Let us search the Scriptures with humility, praying that we may never lose the light of the Gospel. “Lord, increase our faith.” VERSE 14. But when I saw that they walked not uprightly according to the truth of the gospel.
