Augustine of Hippo — as excerpted in the Catena Aurea on John 3:32-36

“(Tr. xiv. c. 11) Having said of the Son, God giveth not the Spirit by measure unto Him; he adds, The Father loveth the Son, and farther adds, and hath given all things into His hand; in order to shew that the Father loveth the Son, in a peculiar sense. For the Father loveth John, and Paul, and yet hath not given all things into their hands. But the Father loveth the Son, as the Son, not as a master his servant: as an only, not as an adopted, Son. Wherefore He hath given all things into His hand; so that, as great as the Father is, so great is the Son; let us not think then that, because He hath deigned to send the Son, any one inferior to the Father has been sent.”
