Galatians 1 - Matthew Henry's Concise Commentary on the Bible

He proves the Divine authority of his doctrine and mission; and declares what he was before his conversion and calling.

In preaching the gospel, the apostle sought to bring persons to the obedience, not of men, but of God. But Paul would not attempt to alter the doctrine of Christ, either to gain their favour, or to avoid their fury. In so important a matter we must not fear the frowns of men, nor seek their favour, by using words of men's wisdom. Concerning the manner wherein he received the gospel, he had it by revelation from Heaven. He was not led to Christianity, as many are, merely by education.

(Ga 1:15-24)
