Augustine of Hippo on Son of man

“Now this ratio of the single to the double arises, no doubt, from the ternary number, since one added to two makes three; but the whole which these make reaches to the senary, for one and two and three make six. And this number is on that account called perfect, because it is completed in its own parts: for it has these three, sixth, third, and half; nor is there any other part found in it, which we can call an aliquot part. The sixth part of it, then, is one; the third part, two; the half, three. But one and two and three complete the same six. And Holy Scripture commends to us the perfection of this number, especially in this, that God finished His works in six days, and on the sixth day man was made in the image of God. And the Son of God came and was made the Son of man, that He might re-create us after the image of God, in the sixth age of the human race.”

“No greater gift could God bestow on men than to give them as their Head His Word, by whom He made all things, and to unite them as members to that Head. Thus the Word became both Son of God and Son of man: one God with the Father, one Man with men. Hence, when we offer our petitions to God, let it not detach itself from its Head. Let it be He, the sole Saviour of His body, our Lord Jesus Christ, the Son of God, who prays for us, who prays in us, and who is prayed to by us. He prays for us as our Priest; He prays in us as our Head; He is prayed to by us as our God. Let us therefore hear both our words in Him and His words in us.... We pray to Him in the form of God; He prays in the form of the slave. There He is the Creator; here He is in the creature. He changes not, but takes the creature and transforms it into Himself, making us one man, head and body, with Himself. We pray therefore to Him, and through Him, and in Him. We pray with Him, and He with us; we recite this prayer of the Psalm in Him, and He recites it in us.”
