If our adversaries choose the former, the meaning is this, that, “as I am sent by the Father and am come down from the Father, so (in accordance therewith) I live by the Father.” But in what character was He sent, and came down, save as Son of Man, even as He Himself said before: “No man hath ascended into heaven, save He that hath come down from heaven as Son of Man.” S. John iii. 13. Then, just as He was sent and came down as Son of Man, so as Son of Man He lives by the Father. Furthermore, he that eateth Him, as eating the Son of Man, doth himself also live by the Son of Man. Thus, He has compared the effect of His Incarnation to His coming.
