Galatians 1:18

"Then after three years I went up to Jerusalem to visit Cephas." What can be more lowly than such a soul? After such successes, wanting nothing of Peter, not even his assent, but being of equal dignity with him, (for at present I will say no more,) he comes to him as his elder and superior. And the only object of this journey was to visit Peter; thus he pays due respect to the Apostles, and esteems himself not only not their better but not their equal. Which is plain from this journey, for Paul was induced to visit Peter by the same feeling from which many of our brethren sojourn with holy men: or rather by a humbler feeling for they do so for their own benefit, but this blessed man, not for his own instruction or correction, but merely for the sake of beholding and honoring Peter by his presence. He says, "to visit Peter;" he does not say to see, but to visit and survey, a word which those, who seek to become acquainted with great and splendid cities, apply to themselves.

Worthy of such trouble did he consider the very sight of Peter; and this appears from the Acts of the Apostles also. For on his arrival at Jerusalem, on another occasion, after having converted many Gentiles, and, with labors far surpassing the rest, reformed and brought to Christ Pamphylia, Lycaonia, Cilicia, and all nations in that quarter of the world, he first addresses himself with great humility to James, as to his elder and superior. Next he submits to his counsel, and that counsel contrary to this Epistle. "Thou seest, brother, how many thousands there are among the Jews of them which have believed; therefore shave thy head, and purify thyself." Accordingly he shaved his head, and observed all the Jewish ceremonies; for where the Gospel was not affected, he was the humblest of all men. But where by such humility he saw any injured, he gave up that undue exercise of it, for that was no longer to be humble but to outrage and destroy the disciples. "And tarried with him fifteen days." To take a journey on account of him was a mark of respect; but to remain so many days, of friendship and the most earnest affection.
