Tractates on the Gospel of John

¹ What is this that the Lord said of the Holy Spirit, when promising that He would come and teach His disciples all truth, or guide them into all truth: “For He shall not speak of Himself; but whatsoever He shall hear, that shall He speak”? For this is similar to what He said of Himself, “I can of my own self do nothing: as I hear, I judge.” But when expounding that, we said that it might be taken as referring to His human nature; so that He seemed as the Son to announce beforehand that His own obedience, whereby He became obedient even unto the death of the cross, would have its place also in the judgment, when He shall judge the quick and the dead; for He shall do so for the very reason that He is the Son of man.

Wherefore He said, “The Father judges no man, but has committed all judgment unto the Son;” for in the judgment He will appear, not in the form of God, wherein He is equal to the Father, and cannot be seen by the wicked, but in the form of man, in which He was made even a little lower than the angels; although then He will come in glory, and not in His original humility, yet in a way that will be conspicuous both to the good and to the bad. Hence He says further: “And He has given Him authority to execute judgment also, because He is the Son of man.” In these words of His own it is made clear that it is not that form that will be presented in the judgment, wherein He was when He thought it not robbery to be equal with God; but that which He assumed when He made Himself of no reputation. For He emptied Himself in assuming the form of a servant; in which, also, for the purpose of executing judgment, He seems to have commended His obedience, when He said, “I can of my own self do nothing: as I hear, I judge.”

For Adam, by whose disobedience, as that of one man, many were made sinners, did not judge as he heard; for he prevaricated what he heard, and of his own self did the evil that he did; for he did not the will of God, but his own: while this latter, by whose obedience, as that also of one man, many are made righteous, was not only obedient even unto the death of the cross, in respect of which He was judged as alive from the dead; but promised also that He would be showing obedience in the very judgment itself, wherein He is yet to act as judge of the quick and the dead, when He said, “I can of my own self do nothing: as I hear, I judge.”

But when it is said of the Holy Spirit, “For He shall not speak of Himself; but whatsoever He shall hear, that shall He speak,” shall we dare to harbor the notion that it was so said in reference to any human nature of His, or the assumption of any creature-form? For it was the Son alone in the Trinity who assumed the form of a servant, a form which in His case was fitted into the unity of His person, or, in other words, that the one person, Jesus Christ, should be the Son of God and the Son of man; and so that we should be kept from preaching a quaternity instead of the Trinity, which God forbid that we should do.

And it is on account of this one personality as consisting of two substances, the divine and the human, that He sometimes speaks in accordance with that wherein He is God, as when He says, “I and my Father are one;” and sometimes in accordance with His manhood, as in the words, “For the Father is greater than I;” in accordance with which also we have understood those words of His that are at present under discussion, “I can of my own self do nothing: as I hear, I judge.” But in reference to the person of the Holy Spirit, a considerable difficulty arises how we are to understand the words, “For He shall not speak of Himself; but whatsoever He shall hear, that shall He speak;” since in it there exists not one substance of Godhead and another of humanity, or of any other creature whatsoever.
