He subjoins, As of the Only-Begotten of the Father: for many prophets, as Moses, Elijah, and others, workers of miracles, had been glorified, and Angels also who appeared unto men, shining with the brightness belonging to their nature; Cherubim and Seraphim too, who were seen in glorious array by the prophets. But the Evangelist withdrawing our minds from these, and raising them above all nature, and every preeminence of fellow servants, leads us up to the summit Himself; as if he said, Not of prophet, or of any other man, or of Angel, or Archangel, or any of the higher powers, is the glory which we beheld; but as that of the very Lord, very King, very and true Only-Begotten Son.
