Nicene and Post-Nicene Fathers, Ser. II, Vol. IV:
The Incarnation of the Word.: As God made man by a word, why not restore him by a word? But (1) creation out of nothing is different from reparation of what already exists. (2) Man was there with a definite need, calling for a definite remedy. Death was ingrained in man's nature: He then must wind life closely to human nature. Therefore the Word became Incarnate that He might meet and conquer death in His usurped territory. (Simile of straw and asbestos.)

§44. As God made man by a word, why not restore him by a word? But (1) creation out of nothing is different from reparation of what already exists. (2) Man was there with a definite need, calling for a definite remedy. Death was ingrained in man’s nature: He then must wind life closely to human nature. Therefore the Word became Incarnate that He might meet and conquer death in His usurped territory. (Simile of straw and asbestos.)

But perhaps, shamed into agreeing with this, they will choose to say that God, if He wished to reform and to save mankind, ought to have done so by a mere fiat 321 , without His word taking a body, in just the same way as He did formerly, when He produced them out of nothing. 2. To this objection of theirs a reasonable answer would be: that formerly, nothing being in existence at all, what was needed to make everything was a fiat and the bare will to do so. But when man had once been made, and necessity demanded a cure, not for things that were not, but for things that had come to be, it was naturally consequent that the Physician and Saviour should appear in what had come to be, in order also to cure the things that were. For this cause, then, He has become man, and used His body as a human instrument. 3. For if this were not the right way, how was the Word, choosing to use an instrument, to appear? or whence was He to take it, save from those already in being, and in need of His Godhead by means of one like themselves? For it was not things without being that needed salvation, so that a bare command should suffice, but man, already in existence, was going to corruption and ruin 322 . It was then natural and right that the Word should use a human instrument and reveal Himself everywhither. 4. Secondly, you must know this also, that the corruption which had set in was not external to the body, but had become attached to it; and it was required that, instead of corruption, life should cleave to it; so that, just as death has been engendered in the body, so life may be engendered in it also. 5. Now if death were external to the body, it would be proper for life also to have been engendered externally to it. But if death was wound closely to the body and was ruling over it as though united to it, it was required that life also should be wound closely to the body, that so the body, by putting on life in its stead, should cast off corruption. Besides, even supposing that the Word had come outside the body, and not in it, death would indeed have been defeated by Him, in perfect accordance with nature, inasmuch as death has no power against the Life; but the corruption attached to the body would have remained in it none the less 323 . 6. For this cause the Saviour reasonably put on Him a body, in order that the body, becoming wound closely to the Life, should no longer, as mortal, abide in death, but, as having put on immortality, should thenceforth rise again and remain immortal. For, once it had put on corruption, it could not have risen again unless it had put on life. And death likewise could not, from its very nature, appear, save in the body. Therefore He put on a body, that He might find death in the body, and blot it out. For how could the Lord have been proved at all to be the Life, had He not quickened what p. 61 was mortal? 7. And just as, whereas stubble is naturally destructible by fire, supposing (firstly) a man keeps fire away from the stubble, though it is not burned, yet the stubble remains, for all that, merely stubble, fearing the threat of the fire—for fire has the natural property of consuming it; while if a man (secondly) encloses it with a quantity of asbestos, the substance said 324 to be an antidote to fire, the stubble no longer dreads the fire, being secured by its enclosure in incombustible matter; 8. in this very way one may say, with regard to the body and death, that if death had been kept from the body by a mere command on His part, it would none the less have been mortal and corruptible, according to the nature of bodies; but, that this should not be, it put on the incorporeal Word of God, and thus no longer fears either death or corruption, for it has life as a garment, and corruption is done away in it.

Restoration by a mere fiat would have shewn God’s power, the Incarnation shews His Love. See Orat. i. 52, note 1, ii. 68, note 1.
