Then answered Jesus and said unto them,
Verily, verily, I say unto you, The Son can do nothing of himself, but what he sees the Father do: for whatsoever things he does, these also does the Son likewise.

Verily, Verily, &c . . . cannot: "not from defect of power," says Euthymius, "but on account of inseparability. For it is impossible that the Son should do anything which the Father does not." So S. Chrysostom and S. Augustine. Except, or unless. This word is not here exceptive, signifying the same as but only. It has the same meaning in Matthew 12:4.
What He seeth: Greek, βλÎπη, i.e, may see. For it is not before He worketh, but as soon as He seeth the Father working, that Hebrews , Christ, worketh with Him. For Christ as God does not produce what is similar, but what is identical with the work of the Father. For the action of the Father, which both see and work together, is the same. I say action, but not the Hypostatic Union, nor the things which depend upon it, for this union has not to do with action, but with the terminus in quo. Wherefore, although the whole Blessed Trinity, Father, Song of Solomon , and Holy Ghost, by their Divine action, have brought about this Hypostatic Union, yet the union itself is terminated in the Song of Solomon , and does not extend to the Father and the Holy Ghost. Wherefore the Son only, not the Father and the Holy Ghost, became incarnate, and died, &c.
Observe, Christ in this place only means to say that He has received from God the Father His Divine Essence, power, and working, as from His Author. He makes use of the word see, as if the Son did nothing except what He seeth the Father do, or what He sees to be the work of His Father. For children and pupils are wont to imitate the ways and deeds of their fathers and teachers. Christ is speaking after the manner of men, or as amongst men it becomes a son to speak of his father.
It may be added that Christ in a proper and theological sense uses the word see, because He proceeds from the Father as the Word, which is the term of the vision and the notional cognition of God the Father. For the Father, as seeing and understanding Himself and all things, produces and begets the Word, and by this communicates to Him His own vision and action. Therefore the Son neither seeth, nor doeth anything except what He seeth the Father see, or do. For He Himself is the Word and the Idea, in whom, as a Term, the Father expresses and imprints all His own vision and cognition, both speculative and practical. The meaning then is this, "Whatever I work, the Father worketh the same, and by altogether the same vision, cognition, will, power, and action. Wherefore if ye accuse Me because I have healed one paralysed on the Sabbath day, ye accuse God the Father also. For He hath wrought this with Me, because He in Me and by Me worketh all things. Indeed, I have received all My work from the Father. Wherefore, if ye believe that God the Father works all things rightly, wisely, and holily, ye ought to believe the same of Me, and therefore that this healing on the Sabbath was a work prudent, holy, and Divine."
Doth likewise: altogether in the same manner, with the same liberty, the same power, the same authority. So S. Gregory Nazianzen (Orat2 , de Filio). S. Cyril says, "They do likewise, or work in like manner, who are altogether of the same nature: but as to things which have a diverse essence there cannot be in them the same mode of working. As therefore He (the Son) is God of true God, He is able to do likewise the same things as the Father."
