For why is Peter distinguished by name from all the rest? Why alone termed by his prophetical name? S. Chrysostome, again tells us why. "Look at Paul's wisdom. _He puts the chief the last. For there he puts that which was strongest among the principal. For it was not so remarkable to shew the rest doing this, as him that was chief, and had been entrusted with the keys of heaven._ But he puts not him alone, but all, as if he would say, whether you look for inferiors, or superiors, you have examples of all. For the brethren of the Lord, being delivered from their first unbelief,[6] were among the principal, though they had not reached the height of Apostles, and, therefore, he put them in the middle, with the highest on the two sides:"[7] words in which he seems to indicate that Peter was as excellent among the Apostles, as they among the rest of the disciples, and the Lord's brethren. Of the superiority contained in the fourth passage, we have spoken above, under another head: and, therefore, proceed to much more remarkable testimonies of S. Paul. In the epistle to the Galatians, S. Paul has occasion[8] to defend his Apostolic authority, and the agreement of the Gospel which he had preached with that of the original Apostles. After referring to his marvellous conversion, he continues, "immediately I condescended not to flesh and blood; neither went I to Jerusalem to the Apostles, who were before me, but I went into Arabia, and again I returned to Damascus. Then, after three years, I went to Jerusalem, to visit Peter, and I tarried with him fifteen days. But other of the Apostles I saw none, saving James, the brother of the Lord." At length, then, S. Paul goes to Jerusalem, and that with a fixed purpose, "to visit Peter." But why Peter only, and not the rest of the Apostles, and the brethren of the Lord?[9] Why speaks he of these, and of James himself, besides, as if he would intimate that he had little care of seeing them? No other answer can be given to such queries, than is shadowed out in the prophetic name of Peter, and contained in the explanation of it given by Christ Himself, "Upon this Rock I will build My Church."
