Jesus said unto them,
My food is to do the will of him that sent me, and to finish his work.
All Commentaries on John 4:34 Go To John 4
Cyril of Alexandria
AD 444
Having wholly torn away the veil from His speech, He shewed them in full translucence the truth, and forthwith introduces Himself as a type unto future teachers of the world, of steadfast and most exceeding excellent zeal, to wit in respect of the duty of teaching, and on this account fitly keeping thought for the needful care of the body secondary. For in saying that it was to Himself most pleasant meat, to do the Will of Him that sent Him and to finish His Work, He limns the office of the Apostolic ministry and clearly shews, what manner of men they ought to be in habit. For it was necessary (as it seems) that they should be strung to taking thought for teaching only, and it behoved them to be so far removed from the pleasure of the body, as at times not even to desire the service necessary for the mere accomplishing its preservation from death.
And let this be said for the present, as tending to the type and pattern of Apostolic polity. But if we must in addition to what has been said, apply ourselves to speak more doctrinally, He says that He was sent, clearly by God the Father, either in respect of the Incarnation, wherein He beamed on the world with Flesh, by the good Pleasure and Approbation of the Father; or as the Word proceeding in some way from the begetting Mind, and sent and fulfilling His decree, not as though taken as a minister of others' wills, but Himself being alike both the Living Word and the most evident Will of the Father, readily saving those that were lost. Therefore in saying that it is the work of Him That hath sent Him, Himself is shewn as its Fulfiller: for all things are by the Father through the Son in the Spirit. For that the Son is the Word and Counsel and Will and Power of the Father is, I suppose, evident to all: but it is no trouble to prove it from the Divine Scripture also. Therefore let any one see that Ho is the Word in this, In the beginning was the Word and the Word was with God and the Word was God: let him see Counsel, in that the Psalmist says, as to God the Father, In Thy Counsel Thou guidedst me and with glory didst Thou receive me: let him see Will again in his saying, Lord in Thy Will give strength to my beauty. For He strengthened the beauty of His saints, that is, their vigour unto every virtue, He, the Living and Hypostatic Will of the Father, that is the SON. That He is Power also, thou shalt again understand hence, Command, O God (he says) Thy strength: strengthen, O God, that which Thou wroughtest for us. Thou seest clearly herein, that by the good Pleasure of God the Father, His Power, that is, the Son, was Incarnate, that He might strengthen this body, which He perfected for us. For if He had not tabernacled among us, neither would the nature of the flesh at all have put off the infirmity of corruption. The Son then being Himself the good Will of the Father, perfects His Work, being shewn forth salvation to them that believe on Him.
But some one will say to this: "If the Son is Himself the Will of the Father, what will was He sent to fulfil? for the fulfilled must needs be other than the fulfiller." What therefore do we say to this? The giving of names indeed demands difference in the things signified, but often there is no difference in respect of God, and word regarding the supreme Nature rejects accuracy herein. For Its Properties are spoken of, not altogether as they are in truth, but as tongue can express, and ear of man hear. For he that seeth darkly, darkly also he speaketh. For what wilt thou do when He Who is by Nature Simple introduceth Himself to us as compound, in that He saith of them of Israel, And their children they made pass through the fire, which I commanded not, neither came it into My heart? for must not the heart needs be other than he in whom it is? and how then shall God be yet conceived of as Simple? The things therefore about God, are spoken of after the manner of men: they are so conceived of, as befits God, and the measure of our tongue will not wrong the Nature That is above all. And therefore even though the Son be found speaking of the Will of the Father, as of something other than He, you will make no difference, attributing fitly to the weakness of our words their not being able to say any thing greater, nor to signify their meaning in any other way.
And let these things bo said in proof of the Son being conceived of as also the Will of the Father; but in the passage before us, no reason will compel us to conceive that the Will of the Father means the Son, but rather we may well receive it as His good Will to the lost.
