Origen
Catena Aurea · Matthäusevangelium 16
For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul? For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works. Verily I say unto you. There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
As much as to say; The Son of Man is now come, but not in glory; for He ought not to have been ordained in His glory to bear our sins; but then He shall come in His glory, when He shall first have made ready His disciples, being made as they are, that He might make them as He is Himself, in the likeness of His glory.
