John 12:50

(Tr. liv) If life everlasting is the Son Himself, and the commandment is life everlasting, what is this but saying, I am the commandment of the Father? And in the same way in the following; Whatsoever I speak therefore, even as the Father said unto Me, so I speak, we must not understand, said unto Me, as if words were spoken to the Only Word. The Father spoke to the Son, as He gave life to the Son; not that the Son knew not, or had not, but that He was the Son. What is meant by, as He said unto Me, so I speak, but that I am the Word who speaks. The Father is true, the Son is truth: the True, begat the Truth. What then could He say to the Truth, if the Truth was perfect from the beginning, and no new truth could be added to Him? That He spake to the Truth then, means that He begat the Truth.

There follow the words: "And I know that His commandment is life everlasting." If, then, the Son Himself is eternal life, and the Father's commandment the same, what else is expressed than this, I am the Father's commandment? And in like manner, in what He proceeds to say, "Whatsoever I speak, even as the Father said unto me, so I speak," let us not be taking the "said unto me" as if the Father used words in speaking to the only Word, or that the Word of God needed words from God. The Father spake to the Son in the same way as He gave life to the Son; not that He knew not the one, or had not the other, but just because He was the Son. What, then, do the words mean, "Even as He said unto me, so I speak;" but just, I speak the truth? So the former said as the Truthful One what the latter thus spake as the Truth. The Truthful begat the Truth. What, then, could He now say to the Truth? For the Truth had no imperfection to be supplied by additional truth. He spake, therefore, to the Truth, because He begat the Truth. And in like manner the Truth Himself speaks what has been said to Him; but only to those who have understanding, and who are taught by Him as the God-begotten Truth. But that men might believe what they had not yet capacity to understand, words that were audible issued from His human lips; sounds passing rapidly away broke on the ear, and speedily completed the little term of their duration: but the truths themselves, of which the sounds are but signs, passed, as it were, into the memory of those who heard them, and have come down to us also by means of written characters as signs addressed to the eye. But it is not thus that the Truth speaks; He speaks inwardly to the souls of the intelligent; He needs no sound to instruct, but floods the mind with the light of understanding.

"For I have not spoken of Myself, but the Father which sent Me, He gave Me a commandment what I should say, and what I should speak." Surely these things were said for their sakes, that they might have no pretense of excuse. Since if this were not the case, what shall He have more than Isaiah? for he too saith the very same thing, "The Lord God giveth me the tongue of the learned, that I should know when I ought to speak a word." (Isa. l. 4, LXX.) What more than Jeremiah? for he too when he was sent was inspired. (Jer. i. 9.) What then Ezekiel? for he too, after eating the roll, so spake. (Ezek. iii. 1.) Otherwise also, they who were about to hear what He said shall be found to be causes of His knowledge. For if when He was sent, He then received commandment what He should say, thou wilt then argue that before He was sent He knew not. And what more impious than these assertions? if (that is) one take the words of Christ in this sense, and understand not the cause of their lowliness? Yet Paul saith, that both he and those who were made disciples knew "what was that good and acceptable and perfect will of God" (Rom. xii. 2), and did the Son not know until He had received commandment? How can this be reasonable? Seest thou not that He bringeth His expressions to an excess of humility, that He may both draw those men over, and silence those who should come after. "And I know that His commandment is life everlasting; whatsoever I speak therefore, even as the Father said unto Me, so I speak." Seest thou the humility of the words? For he that hath received a commandment is not his own master. Yet He saith, "As the Father raiseth up the dead and quickeneth them, even so the Son quickeneth whom He will." (c. v. 21.) Hath He then power to quicken whom He will, and to say what He will hath He not power? What He intendeth then by the words is this; "The action hath not natural possibility, that He should speak one set of words, and I should utter another." "And I know that His commandment is life everlasting." He said this to those that called Him a deceiver, and asserted that He had come to do hurt. But when He saith, "I judge not," He showeth that He is not the cause of the perdition of these men. By this He all but plainly testifies, when about to remove from, and to be no more with, them, that "I converse with you, speaking nothing as of Myself, but all as from the Father." And for this cause He confined His discourse to them to humble expressions, that He might say, "Even until the end did I utter this, My last word, to them." What word was that? "As the Father said unto Me, so I speak." "Had I been opposed to God I should have said the contrary, that I speak nothing of what is pleasing to God, so as to attract the honor to Myself, but now I have so referred all things to Him, as to call nothing My own. Why then do ye not believe Me when I say that 'I have received a commandment,' and when I so vehemently remove your evil suspicion respecting rivalry? For as it is impossible for those who have received a commandment to do or say anything but what their senders wish, as long as they fulfill the commandment, and do not forge anything; so neither is it possible for Me to say or do anything except as My Father willeth. For what I do He doeth, because He is with Me, and 'the Father hath not left Me alone.'" (c. viii. 29.) Seest thou how everywhere He showeth Himself connected with Him who begat Him, and that there is no separation? For when He saith, "I am not come of Myself," He saith it not, as depriving Himself of power, but as taking away all alienation or opposition. For if men are masters of themselves, much more the Only-begotten Son.

Since the Son is the Word of the Father, and reveals completely what is in the mind of the Father, He says He receives a commandment what He should say, and what He should speak: just as our word, if we say what we think, brings out what is in our minds. And I know that His commandment is life everlasting.
