The Word of God thus acted consistently in assuming a body and using a human instrument to vitalize the body. He was consistent in working through man to reveal Himself everywhere, as well as through the other parts of His creation, so that nothing was left void of His Divinity and knowledge. For I take up now the point I made before, namely that the Savior did this in order that He might fill all things everywhere with the knowledge of Himself, just as they are already filled with His presence, even as the Divine Scripture says, “The whole universe was filled with the knowledge of the Lord.” (Isaiah 11:9) If a man looks up to heaven he sees there His ordering; but if he cannot look so high as heaven, but only so far as men, through His works he sees His power, incomparable with human might, and learns from them that He alone among men is God the Word. Or, if a man has gone astray among demons and is in fear of them, he may see this Man drive them out and judge therefrom that He is indeed their Master. Again, if a man has been immersed in the element of water and thinks that it is God—as indeed the Egyptians do worship water—he may see its very nature changed by Him and learn that the Lord is Creator of all. And if a man has gone down even to Hades, and stands awestruck before the heroes who have descended thither, regarding them as gods, still he may see the fact of Christ’s resurrection and His victory over death, and reason from it that, of all these, He alone is very Lord and God.
For the Lord touched all parts of creation, and freed and undeceived them all from every deceit.
As St. Paul says, “Having put off from Himself the principalities and the powers, He triumphed on the cross,” (Colossians 2:15) so that no one could possibly be any longer deceived, but everywhere might find the very Word of God. For thus man, enclosed on every side by the works of creation and everywhere—in heaven, in Hades, in men and on the earth, beholding the unfolded Godhead of the Word, is no longer deceived concerning God, but worships Christ alone, and through Him rightly knows the Father.
