John 5:23

(vii. de Trin. c. 21) The conclusion then stands good against all the fury of heretical minds. He is the Son, because He does nothing of Himself: He is God, because, whatsoever things the Father doeth, He doeth the same; They are one, because They are equal in honour: He is not the Father, because He is sent.

"He that honoreth not the Son honoreth not the Father which hath sent Him." Seest thou how the honor of the Son is connected with that of the Father? "What of that?" saith one. "We see the same in the case of the Apostles; 'He,' saith Christ, 'who receiveth you receiveth Me.'" But in that place He speaketh so, because He maketh the concerns of His servants His own; here, because the Essence and the Glory is One with that of the Father. Therefore it is not said of the Apostles "that they may honor," but rightly He saith, "He that honoreth not the Son honoreth not the Father." For where there are two kings, if one is insulted the other is insulted also, and especially when he that is insulted is a son. He is insulted even when one of his soldiers is maltreated; not in the same way as in this case, but as it were in the person of another, while here it is as it were in his own. Wherefore He beforehand said, "That they should honor the Son even as they honor the Father," in order that when He should say, "He that honoreth not the Son honoreth not the Father," thou mightest understand that the honor is the same. For He saith not merely, "he that honoreth not the Son," but "he that honoreth Him not so as I have said" "honoreth not the Father."

And immediately, then, after the judgment mentioned, all which the Father, not judging any man, hath given to the Son, what shall be? What follows? "That all may honor the Son, even as they honor the Father." The Jews honor the Father, despise the Son. For the Son was seen as a servant, the Father was honored as God. But the Son will appear equal with the Father, that all may honor the Son, even as they honor the Father. This we have, therefore, now in faith. Let not the Jew say, "I honor the Father; what have I to do with the Son?" Let him be answered, "He that honoreth not the Son, honoreth not the Father. Thou liest every way; thou blasphemest the Son, and dost wrong to the Father. For the Father sent the Son, and thou despisest Him whom the Father sent. How canst thou honor the sender, who blasphemest the sent?"

Behold, says some one, the Son has been sent; and the Father is greater, because He sent. Withdraw from the flesh; the old man suggests oldness in time. Let the ancient, the perpetual, the eternal, to thee the new, call off thy understanding from time to this. Is the Son less because He is said to have been sent? I hear of a sending, not a separation. But yet, saith he, among men we see that he who sends is greater than he who is sent. Be it so; but human affairs deceive a man; divine things purge him. Do not regard things human, in which the sender appears greater, the sent less. Notwithstanding, things human themselves bear testimony against thee. Just as, for example, if a man wishes to ask a woman to wife, and, not being able to do this in person, sends a friend to ask for him. And there are many cases in which the greater is chosen to be sent by the less. Why, then, wouldst thou now raise a captious objection, because the one has sent, the other is sent? The sun sends out a ray, but does not separate it; the moon sends out her sheen, but does not separate it; a lamp sheds light, but does not separate it: I see there a sending forth, not a separation.

Consider how different it is in the case of things human, from which you wish to deduce examples for things divine. A man that sends remains himself behind, while only the man that is sent goes forward. Does the man who sends go with him whom he sends? Yet the Father, who sent the Son, has not departed from the Son. Hear the Lord Himself saying, "Behold, the hour is coming, when every one shall depart to his own, and ye will leave me alone; but I am not alone, because the Father is with me." How has He, with whom He came, sent Him? How has He, from whom He has not departed, sent Him? In another place He said, "The Father abiding in me doeth the works." Behold, the Father is in Him, works in Him. The Father sending has not departed from the Son sent, because the sent and the sender are one.
