No man has seen God at any time; the only begotten Son, who is in the bosom of the Father, he has declared him.

John Chrysostom
AD 407
Or thus; the Evangelist after showing the great superiority of Christ’s gifts, compared with those dispensed by Moses, wishes in the next place to supply an adequate reason for the difference. The one being a servant was made aminister of a lesser dispensation: but the other Who was Lord, and Son of the King, brought us far higher things, being ever coexistent with the Father, and beholding Him. Then follows, No man has seen God at any time .
If the old fathers had seen That very Nature, they would not have contemplated It so variously, for It is in Itself simple and without shape; It sits not, It walks not; these are the qualities of bodies. Whence he said through the Prophet, I have multiplied visions, and used similitudes, by the ministry of the Prophets: i.e. I have condescended to them, I appeared that which I was not. For inasmuch as the Son of God was about to manifest Himself to us in actual flesh, men were at first raised to the sight of God, in such ways as allowed of their seeing Him.
That very existence which is God, neither Prophets, nor even Angels, nor yet Archangels, have seen. For inquire of the Angels; they say nothing concerning His Substance; but sing, Glory to Godin the highest, and Peace on earth to men of good will. Nay, ask even Cherubim and Seraphim; you will hear only in reply the mystic melody of devotion, and that heaven and earth are full of His glory.
In this complete sense only the Son and the Holy Spirit see the Father. For how can created nature see that which is uncreated? So then no man knows the Father as the Son knows Him: and hence what follows, The Only-Begotten Son, Who is in the bosom of the Father, He has declared, Him. That we might not be led by the identity of the name, to confound Him with the sons made so by grace, the article is annexed in the first place; and then, to put an end to all doubt, the name Only-Begotten is introduced.
He adds, Which is in the bosom of the Father. To dwell in the bosom is much more than simply to see. For he who sees simply, has not the knowledge thoroughly of that which he sees; but he who dwells in the bosom, knows every thing. When you hear then that no one knows the Father save the Son, do not by any means suppose that he only knows the Father more than any other, and does not know Him fully. For the Evangelist sets forth His residing in the bosom of the Father on this very account: viz. to show us the intimate converse of the Only-Begotten, and His co-eternity with the Father.
But what has He declared? That God is one. But this the rest of the Prophets and Moses proclaim: what else have we learnt from the Son Who was in the bosom of the Father? In the first place, that those very truths, which the others declared, were declared through the operation of the Only Begotten: in the next place, wehave received a far greater doctrine from the Only Begotten; viz. that God is a Spirit, and those who worship Him must worship Him in spirit and in truth; and that God is the Father of the Only Begotten.
The text then, No man has seen God at any time, applies not to the Father only, but also to the Son: for He, as Paul said, is the Image of the invisible God; but He who is the Image of the Invisible , must Himself also be invisible.
