Eternal life is knowing Father and Christ; glory and oneness

“…the Father loves you, because you have loved me, because I came forth from the Father.”

“And this is eternal life, that they know you, the only true God, and Jesus Christ whom you sent.” If knowledge of Jesus Christ is necessarily joined to, and enters together with, knowledge of the only true God, and this procures eternal life, how is it not clear to all that Christ is true God? For the Word became flesh, and remained Word.

“That the world may believe that you sent me; and the glory that you have given me I have given them, that they may be one as we are one; I in them and you in me, that they may be perfected into one.” Setting the eye of understanding carefully on the force of what is before us, let us consider what is in it. What glory does the Son say he has received from the Father and given to us? He himself will free us from searching this out when he says “that they may be one as we are one.” For in natural identity the Word from God is one with his own Father, even if each is understood in his own hypostasis. And how has he also come to be in us? In the same way — I mean essentially and naturally? Yet God’s nature would be wholly incompatible with creation, I mean in identity according to essence. How then has the One above creation come to be in us naturally? He became human, so that just as he is one with the Father in the nature of the deity, so he may also become one with us in the relation according to humanity; for in this way we too are perfected into one.
