78. “This is the living bread, which came down from heaven.” S. John vi. 51. This bread is His flesh, even as He Himself said: “This bread which I will give is My flesh.” S. John vii. 52. This is He Who came down from heaven, this is He Whom the Father hath sanctified and sent into this world. Even the letter itself teaches us that not the Godhead but the flesh needed sanctification, for the Lord Himself said, “And I sanctify Myself for them,” S. John xvii. 19. in order that thou mayest acknowledge that He is both sanctified in the flesh for us, and sanctifies by virtue of His Divinity.
