Then said they unto him, Where is your Father? Jesus answered,
You neither know me, nor my Father: if you had known me, you should have known my Father also.

Jesus answered, Neither Me do ye know nor My Father, if ye had known Me, ye should have known My Father also.
True is the word and in no respect can it be accused of lying. For they who indeed suppose Christ to be of Joseph, or of fornication, and who know not that the Word beamed forth of God the Father, how will they not with reason hear, Neither Me do ye know nor My Father? For if they had known the Word that beamed forth of God the Father, and was for our sakes made in the flesh, according to the Divine Scripture, they would have known Him too Who begat Him. For most accurate knowledge of the Father is through the Son implanted in the understanding of the more zealous after learning, as He too affirmed, saying unto God the Father, I manifested Thy Name to the men, and again, Thy knowledge was made marvellous by Me. For since we know the Son, we know by Him Him Who begat Him. For through Both is brought in the perception of the Other: and when the Father is mentioned, the memory of His Offspring surely comes in with it, and again with the signification of the Son, the Name of Him Who begat Him comes in too. For therefore is the Son a Door (so to speak) and way leading unto the knowledge of the Father. And so does He say, No man cometh unto the Father but by Me. For we must needs first learn (as is possible) what the Son is by Nature; and so, as from Image and most accurate Impress, understand well the Archetype. For in the Son is the Father seen, and in the Nature of His own Offspring as in a mirror, is He Perfectly seen. But if this be true, as it is true, let the God-opposing Arian blush. For needs must the Impress of His Essence be in every way and manner like to Him, lest ought else than what the Father is, be supposed to be perfectly beaming forth in the Son. And if He love to be known in the Son and to shine forth in Him, He knows (I suppose) of a surety that He is Consubstantial too, and in nothing whatever inferior to His Own inherent Glory: for He would not have chosen to be believed to be in lesser case than He is by Nature. And since He loves and has willed this, how must we not needs now confess that the Son is every way like the Father, in order that through Him we may know Him also That begat Him, as we have already said, ascending aright from the Image to the Archetype, and be able to have an unblameable conception of the Holy Trinity?
Thus then he who knoweth the Son, knoweth the Father too. But consider how the Lord after having said the truth to the Jews, interweaves some other device also in His speech; for having said clearly, Neither Me do ye know nor My Father, He draws gently off the mind of the Jews, that they should not think only humanly of Him, nor suppose that He is in truth the son of Joseph who was taken economically but should rather seek and enquire Who is the Word in Flesh, Who His Father by Nature.
