§17. How the Incarnation did not limit the ubiquity of the Word, nor diminish His Purity. (Simile of the Sun.)
For He was not, as might be imagined, circumscribed in the body, nor, while present in the body, was He absent elsewhere; nor, while He moved the body, was the universe left void of His working and Providence; but, thing most marvellous, Word as He was, so far from being contained by anything, He rather contained all things Himself; and just as while present in the whole of Creation, He is at once distinct in being from the universe, and present in all things by His own power,—giving order to all things, and over all and in all revealing His own providence, and giving life to each thing and all things, including the whole without being included, but being in His own Father alone wholly and in every respect,—2. thus, even while present in a human body and Himself quickening it, He was, without inconsistency, quickening the universe as well, and was in every process of nature, and was outside the whole, and while known from the body by His works, He was none the less manifest from the working of the universe as well. 3. Now, it is the function of soul to behold even what is outside its own body, by acts of thought, without, however, working outside its own body, or moving by its presence things remote from the body. Never, that is, does a man, by thinking of things at a distance, by that fact either move or displace them; nor if a man were to sit in his own house and reason about the heavenly bodies, would he by that fact either move the sun or make the heavens revolve. But he sees that they move and have their being, without being actually able to influence them. 4. Now, the Word of God in His mans nature was not like that; for He was not bound to His body, but rather was Himself wielding it, so that He was not only in it, but was actually in everything, and while external to the universe, abode in His Father only. 5. And this was the wonderful thing that He was at once walking as man, and as the Word was quickening all things, and as the Son was dwelling with His Father. So that not even when the Virgin bore Him did He suffer any change, nor by being in the body was [His glory] dulled: but, on the contrary, He sanctified the body also. 6. For not even by being in the universe does He share in its nature, but all things, on the contrary, are quickened and sustained by Him. 7. For if the sun too, which was made by Him, and which we see, as it revolves in the heaven, is not defiled 248 by touching the bodies upon earth, nor is it put out by darkness, but on the contrary itself illuminates and cleanses them also, much less was the all-holy Word of God, Maker and Lord also of the sun, defiled by being made known in the body; on the contrary, being incorruptible, He quickened and cleansed the body also, which was in itself mortal: “who 249 did,” for so it says, “no sin, neither was guile found in His mouth.”
