Ante-Nicene Fathers, Vol IX:
Origen's Commentary on the Gospel of Matthew.: Chapter XXIX

29.  The Coming of the Son of Man in Glory.

“For the Son of man shall come in the glory of His own Father with His angels.” 5737   Now, indeed, the Son of man has not come in His glory; “for we saw Him, and He had no form nor beauty; but His form was dishonoured and defective compared with the sons of men; He was a man in affliction and toil, and acquainted with the enduring of sickness, because His face was turned away, He was dishonoured and not esteemed.” 5738   And it was necessary that He should come in such form that He might bear our sins 5739 and suffer pain for us; for it did not become Him in glory to bear our sins and suffer pain for us.  But He also comes in glory, having prepared 5740 the disciples through that epiphany of His which has no form nor beauty; and, having become as they that they might become as He, “conformed to the image of His glory,” 5741 since He formerly became conformed to “the body of our humiliation,” 5742 when He “emptied Himself and took upon Him the form of a servant,” 5743 He is restored to the image of God and also makes them conformed unto it.
