5 Shame upon Marcion, shame upon Paul of Samosata, for refusing to see what those wise men saw—the forefathers of the Church; for I am not ashamed so to call them. Let Marcion be ashamed, beholding God worshipped in the flesh. Let Paul be ashamed, beholding Him worshipped as not being merely a man. As to His being in the flesh, that first is signified by the swaddling clothes and the manger; as to their not worshipping Him as a mere man, they declare it, by offering Him, at that unripe age, such gifts as were meet to be offered to God. And together with them let the Jews also be ashamed, seeing themselves anticipated by barbarians and magi, while they submit not so much as to come after them. For indeed what happened then was a type of the things to come, and from the very beginning it was shown that the Gentiles would anticipate their nation.
“But how was it,” one may ask, “that not at the beginning, but afterwards, He said, 'Go, and make disciples of all nations'”? Because the occurrence was a type, as I said, of the future, and a sort of declaration of it beforehand. For the natural order was that Jews should come unto Him first; but forasmuch as they of their own choice gave up their proper benefit, the order of things was inverted. Since not even in this instance should the wise men have come before the Jews, nor should persons from so great a distance have anticipated those who were settled about the very city, nor should those who had heard nothing have prevented them that were nurtured in so many prophecies. But because they were exceedingly ignorant of their own blessings, those from Persia anticipate those at Jerusalem. And this indeed is what Paul also says: “It was necessary that the word of the Lord should first have been spoken to you, but seeing you have judged yourselves unworthy, lo, we turn to the Gentiles.” For even though before they did not obey, at any rate when they heard it from the wise men, they ought to have made all haste; but they would not. Therefore, while those are slumbering, these run before.
