For my flesh is food indeed, and my blood is drink indeed.
All Commentaries on John 6:55 Go To John 6
Theophilus of Antioch
AD 184
For we do not eat God simply, God being impalpable and incorporeal; nor again, the flesh of man simply, which would not profit us. But God having taken flesh into union with Himself; that flesh is quickening. Not that it has changed its own for the Divine nature; but, just as heated iron remains iron, with the action of the heat in it; so our Lord's flesh is quickening, as being the flesh of the Word of God.
