St. Hilary of Poitiers: "The true nature of the body and the blood"

“WE speak in an absurd and godless manner about the divinity of Christ’s nature in us—unless we have learned it from Him. He Himself declares: ‘For my flesh is food indeed, and my blood is drink indeed. He who eats my flesh and drinks my blood abides in me and I in him’ (Jn. 6:56, 7). It is no longer permitted us to raise doubts about the true nature of the body and the blood, for, according to the statement of the Lord Himself as well as our faith, this is indeed flesh and blood. And these things that we receive bring it about that we are in Christ and Christ is in us. Is not this the truth? Those who deny that Jesus Christ is true God are welcome to regard these words as false. He Himself, therefore, is in us through His flesh, and we are in Him, while that which we are with Him is in God.”
