10 Glory be to Him Who received from us that He might give to us; that through that which is ours we might more abundantly receive of that which is His! Yea through that Mediator, mankind was able to receive life from its helper, as through a Mediator it had received in the beginning death from its slayer. You are He Who made for Yourself the body as a servant, that through it You might give to them that desire You, all that they desire. Moreover in You were made visible the hidden wishes of them that slew [You] and buried [You]; through this, that You clothed Yourself in a body.
For taking occasion by that body of Yours, Your slayers slew You, and were slain by You; and taking occasion by Your body, Your buriers buried You, and were raised up with You. That Power Which may not be handled came down and clothed itself in members that may be touched; that the needy may draw near to Him, that in touching His manhood they may discern His Godhead. For that dumb man [whom the Lord healed] with the fingers of the body, discerned that He had approached his ears and touched his tongue; nay, with his fingers that may be touched, he touched Godhead, that may not be touched; when it was loosing the string of his tongue, and opening the clogged doors of his ears.
For the Architect of the body and Artificer of the flesh came to him, and with His gentle voice pierced without pain his thickened ears. And his mouth which was closed up, that it could not give birth to a word, gave birth to praise to Him Who made its barrenness fruitful in the birth of words. He, then, Who gave to Adam that he should speak at once without teaching, Himself gave to the dumb that they should speak easily, tongues that are learned with difficulty.
