42. The words of the Apostle's faith are a barrier against your reckless and frenzied profanity, which forbids you to turn the freedom of speculation into licence, and wander into error. Every tongue, he says, shall confess that Jesus is Lord in the glory of God the Father [1027] . The Father has glorified Him in Himself, therefore He must be confessed in the glory of the Father. And if He is to be confessed in the Father's glory, and the Father has glorified Him in Himself, is He not plainly all that His Father is, since the Father has glorified Him in Himself and He is to be confessed in the Father's glory? He is now not merely in the glory of God, but in the glory of God the Father. The Father glorifies Him, not with a glory from without, but in Himself. By taking Him back into that glory, which belongs to Himself, and which He had with Him before, the Father glorifies Him with Himself and in Himself. Therefore this confession is inseparable from Christ even in the humiliation of His manhood, as He says, And this is eternal life, that they should know Thee, the only true God, Him, Whom Thou didst send, even Jesus Christ [1028] ; for firstly there is no life eternal in the confession of God the Father without Jesus Christ, and secondly Christ is glorified in the Father. Eternal life is precisely this, to know the only true God and Him, Whom He sent, even Jesus Christ; deny that Christ is true God, if you can have life by believing in God without Him. As for the truth that God the Father is the only true God; let this be untrue of the God Christ, unless Christ's glory is wholly in the only true God the Father. For if the Father glorifies Him in Himself, and the Father is the only true God, Christ is not outside the only true God, since the Father, Who is the only true God, glorifies in Himself Christ, Who is raised into the glory of God. And in that He is glorified by the only true God in Himself, He is not estranged from the only true God, for He is glorified by the true God in Himself, the only God.
43. But perhaps the godless unbeliever meets the pious believer with the assertion that we cannot understand of the true God a confession of powerlessness, such as, Verily, verily, I say unto you, The Son can do nothing of Himself, but what He hath seen the Father doing [1029] . If the twofold anger [1030] of the Jews had not demanded a twofold answer, it would indeed have been a confession of weakness, that the Son could do nothing of Himself, except what He had seen the Father doing. But Christ was answering in the same sentence the double charge of the Jews, who accused Him of violating the Sabbath, and of making Himself equal with God by calling God His Father. Do you think, then, that by fixing attention upon the form of His reply you can withdraw it for the substance? We have already treated of this passage in another book [1031] ; yet as the exposition of the faith gains rather than loses by repetition, let us ponder once more on the words, since the occasion demands it of us.
44. Hear how the necessity for the reply arose:--And for this cause did the Jews persecute Jesus, and sought to kill Him, because He did these things on the Sabbath [1032] . Their anger was so kindled against Him, that they desired to kill Him, because He did His works on the Sabbath. But let us see also what the Lord answered, My Father worketh even until now, and I work [1033] . Tell us, heretic, what is that work of the Father; since through the Son, and in the Son, are all things, visible and invisible? You, who are wise beyond the Gospels, have doubtless obtained from some other secret source of learning the knowledge of the Father's work, to reveal Him to us. But the Father works in the Son, as the Son Himself says, The words that I say unto you, I speak not from Myself, but the Father who abideth in Me, He doeth His works [1034] . Do you grasp the meaning of the words, My Father worketh even until now? He speaks that we may recognise in Him the power of the Father's nature employing the nature, which has that power, to work on the Sabbath. The Father works in Him while He works; without doubt, then, He works along with the working of the Father, and therefore He says, My Father worketh even until now, that this present work of His words and actions may be regarded as the working of the Father's nature in Himself. This worketh even until now identifies the time with the moment of speaking, and therefore we must regard Him as referring to that very work of the Father's which He was then doing, for it implies the working of the Father at the very time of His words. And lest the Faith, being restricted to a knowledge of the Father only, should fail of the hope of eternal life, He adds at once, And I work; that is, what the Father worketh even until now, the Son also worketh. Thus He expounds the whole of the faith; for the work which is now, belongs to the present time; and if the Father works, and the Son works, no union exists between them, which merges them into a single Person [1035] . But the wrath of the bystanders is now redoubled. Hear what follows, For this cause, therefore, the Jews sought the more to kill Him, because He not only broke the Sabbath, but because He called God His own Father, making Himself equal with God [1036] . Allow me here to repeat that, by the judgment of the Evangelist and by common consent of mankind, the Son is in equality with the Father's nature; and that equality cannot exist except by identity of nature. The begotten cannot derive what it is save from its source and the thing generated cannot be foreign to that which generates it, since from that alone has it come to be what it is. Let us see, then, what the Lord replied to this double outburst of wrath, Verily, verily, I say unto you, the Son can do nothing of Himself, but what He hath seen the Father doing: for what things soever He doeth, these the Son also doeth in like manner [1037] .
45. Unless we regard these words as an integral part of His statement, we do them violence by forcing upon them an arbitrary and unbelieving interpretation. But if His answer refers to the grounds of their anger, our faith expresses rightly what He meant to teach, and the perversity of the ungodly is left without support for its profane delusion. Let us see then whether this reply is suitable to an accusation of working on the Sabbath. The Son can do nothing of Himself, but what He hath seen the Father doing. He has said just above, My Father worketh even until now, and I work. If by virtue of the authority of the Father's nature within Him, all that He works, He works with the Father in Him, and the Father works even until now on the Sabbath, then the Son, Who pleads the authority of the Father's working, is acquitted of blame. For the words, can do nothing, refer not to strength but to authority; He can do nothing of Himself, except what He has seen. Now, to have seen does not confer the power to do, and therefore He is not weak, if He can do nothing without having seen, but His authority is shewn to depend on seeing. Again the words, unless He hath seen, signify the consciousness derived from seeing, as when He says to the Apostles, Behold I say unto you, Lift up your eyes, and look on the fields, that they are white already unto harvest [1038] . With the consciousness that the Father's nature is abiding in Him, and working in Him when He works, to forestall the idea that the Lord of the Sabbath has violated the Sabbath, He pronounces that, The Son can do nothing of Himself, but what He hath seen the Father doing. And thus He demonstrates that His every action springs from His consciousness of the nature working within Him; when He works on the Sabbath, the Father worketh even until now on the Sabbath. In what follows, however, He refers to the second cause of their indignation, For what things soever He doeth, the Son doeth in like manner. Is it false that, what things soever the Father doeth, the Son doeth in like manner? Does the Son of God admit a distinction between the Father's power and working and His own? Does He shrink from claiming the equality of homage befitting an equal in power and nature? If He does, disdain His weakness, and degrade Him from equality of nature with the Father. But He Himself says only a little later, That all may honour the Son, even as they honour the Father, He that honoureth not the Son, honoureth not the Father which sent Him [1039] . Discover, if you can, the inferiority, when Both are equal in honour; make out the weakness, when Both work with the same power.
46. Why do you misrepresent the occasion of the reply in order to detract from His divinity? To the working on the Sabbath He answers that He can do nothing of Himself, but what He hath seen the Father doing: to demonstrate His equality, He professes to do what things soever the Father doeth. Enforce your charge of weakness, by His answer concerning the Sabbath, if you can disprove that what things soever the Father doeth, the Son doeth in like manner. But if what things soever includes all things without exception; in what is He found weak, when there is nothing that the Father doeth, which He cannot also do? Where is His claim to equality refuted by any episode of weakness, when one and the same honour is demanded for Him and for the Father? If Both have the same power in operation, and both claim the same reverence in worship, I cannot understand what dishonour of inferiority can exist, since Father and Son possess the same power of operation, and equality of honour.
47. Although we have treated this passage as the facts themselves explain it, yet to prove that the Lord's words, The Son can do nothing of Himself, but what He hath seen the Father doing, so far from supporting this unholy degradation of His nature, testify to His conscious possession of the nature of the Father, by Whose authority He worked on the Sabbath, let us shew them that we can produce another saying of the Lord, which bears upon the question, I do nothing of Myself, but as the Father taught Me, I speak these things. And He that sent Me is with Me: He hath not left Me alone, for I do always the things that are pleasing to Him [1040] . Do you feel what is implied in the words, The Son can do nothing, but what He hath seen the Father doing? Or what a mystery is contained in the saying, I can do nothing of myself, and He hath not left me alone, for I do always the things that are pleasing to Him? He does nothing of Himself, because the Father abides in Him; can you reconcile with this the fact that the Father does not leave Him, because He does the things which are pleasing to Him? Your interpretation, heretic, sets up a contradiction between these two statements, that He does nothing of Himself, unless taught of the Father abiding in Him, and that the Father abides in Him, because He does always the things which are pleasing to Him. For if the Father's abiding in Him means that He does nothing of Himself, how could He have deserved that the Father should abide in Him, by doing always the things which are pleasing to the Father. It is no merit, not to do of oneself what one does. Conversely, how are the Son's deeds pleasing to the Father, if the Father Himself, abiding in the Son, be their Author? Impiety, thou art in a sore strait; the well-armed piety of the faith hath hemmed thee in. The Son is either an Agent, or He is not. If He is not an Agent, how does He please by his acts? If He is an Agent, in what sense are deeds, done not of Himself, His own? On the one hand, He must have done the things which are pleasing; on the other, it is no merit to have done, yet not of oneself, what one does.
48. But, my opponent, the unity of Their nature is such, that the several action of Each implies the conjoint action of Both, and Their joint activity a several activity of Each. Conceive the Son acting, and the Father acting through Him. He acts not of Himself, for we have to explain how the Father abides in Him. He acts in His own Person, for in accordance with His birth as the Son, He does Himself what is pleasing. His acting not of Himself would prove Him weak, were it not the case that He so acts that what He does is pleasing to the Father. But He would not be in the unity of the divine nature, if the deeds which He does, and wherein He pleases, were not His own, and He were merely prompted to action by the Father abiding in Him. The Father then in abiding in Him, teaches Him, and the Son in acting, acts not of Himself; while, on the other hand, the Son, though not acting of Himself, acts Himself, for what He does is pleasing. Thus is the unity of Their nature retained in Their action, for the One, though He acts Himself, does not act of Himself, while the Other, Who has abstained from action, is yet active.
