John 8:42

(vi. de Trin. c. 30) It was not that the Son of God condemned the assumption of so religious a name; that is, condemned them for professing to be the sons of God, and calling God their Father; but that He blamed the rash presumption of the Jews in claiming God for their Father, when they did not love the Son. For I proceeded forth, and came from God. To proceed forth, is not the same with to come. When our Lord says that those who called God their Father, ought to love Him, because He came forth from God, He means that His being born of God was the reason why He should be loved: the proceeding forth, having reference to His incorporeal birth. Their claim to be the sons of God, was to be made good by their loving Christ, Who was begotten from God. For a true worshipper of God the Father must love the Son, as being from Godf. And he only can love the Father, who believes that the Son is from Him. (lib. v. ibid.) In what follows, He teaches that His origin is not in Himself; Neither came I of Myself, but He sent Me.

"What sayest thou? Ye have God for your Father, and do ye blame Christ for asserting this?" Seest thou that He said that God was His Father in a special manner? When therefore He had cast them out of their relationship to Abraham, having nothing to reply, they dare a greater thing, and betake themselves to God. But from this honor also He expelleth them, saying, "If God were your Father, ye would love Me; for I proceeded forth and came from God; neither came I of Myself, but He sent Me. Why do ye not understand My speech? Even because ye cannot hear My word."

"Why do ye not understand My speech?" Since they were always doubting, saying, "What is it that he saith, 'Whither I go ye cannot come'?" therefore He telleth them, "Ye do not understand My speech," "because ye have not the word of God. And this cometh to you, because that your understanding is groveling, and because what is Mine is far too great for you." But what if they could not understand? Not to be able here means not to be willing; for "ye have trained yourselves to be mean, to imagine nothing great." Because they said that they persecuted Him as being themselves zealous for God on this account He everywhere striveth to show that to persecute Him is the act of those who hate God, but that, on the contrary, to love Him is the act of those who know God.

(Tr. xlii. 8) This then is the eternal procession, the proceeding forth of the Word from God: from Him It proceeded as the Word of the Father, and came to us: The Word was made flesh. (c. 1:14) His advent is His humanity: His staying, His divinity. Ye call God your Father; acknowledge Me at least to be a brother.

Has falsehood indeed found something to say, and should not truth find its fitting reply? Let us hear what they say: let us hear what they hear. "We have one Father," they say, "even God. Then said Jesus unto them, If God were your Father, ye would [doubtless] love me; for I proceeded forth and came from God; neither came I of myself, but He sent me." Ye call God Father; recognize me, then, as at least a brother. At the same time He gave a stimulus to the hearts of the intelligent, by touching on that which He has a habit of saying, "I came not of myself: He sent me. I proceeded forth and came from God." Remember what we are wont to say: From Him He came; and from whom He came, with Him He came. The sending of Christ, therefore, is His incarnation. But as respects the proceeding forth of the Word from God, it is an eternal procession. Time holds not Him by whom time was created. Let no one be saying in his heart, Before the Word was, how did God exist? Never say, Before the Word of God was. God was never without the Word, because the Word is abiding, not transient; God, not a sound; by whom the heaven and earth were made, and which passed not away with those things that were made upon the earth. From Him, then, He proceeded forth as God, the equal, the only Son, the Word of the Father; and came to us, for the Word was made flesh that He might dwell among us. His coming indicates His humanity; His abiding, His divinity.
