Augustine of Hippo

(de Trin. c. 29. [xiii.]) For this, viz. that the Father hath given all judgment unto the Son, does not mean that He begat the Son with this attribute, as is meant in the words, So hath He given to the Son to have life in Himself. For if so, it would not be said, The Father judgeth no man, because, in that the Father begat the Son equal, He judgeth with the Son. What is meant is, that in the judgment, not the form of God but the form of the Son of man will appear; not because He will not judge Who hath given all judgment to the Son; since the Son says of Him below, There is one that seeketh and judgeth, (c. 8.) but the Father judgeth no man; i. e. no one will see Him in the judgment, but all will see the Son, because He is the Son of man, even the ungodly who will look on Him Whom they pierced. (Zech. 12)
