On the Power and Glory of Christ
The following is from the pen of St. Athanasius (ca. 293-373), the great champion and defender of the deity of Christ at the Council of Nicaea. It's from his work entitled De Incarnatione Verbi Dei (On the Incarnation of the Word of God). In the following passage, he speaks of the power of Christ over all the forces of evil.
When did people begin to abandon the worship of idols, unless it were since the very Word of God came among men? When have oracles ceased and become void of meaning, among the Greeks and everywhere, except since the Saviour has revealed Himself on earth? When did those whom the poets call gods and heroes begin to adjudged as mere morals, except when the Lord took the spoils of death and preserved incorruptible the body He had taken, raising it from among the dead? Or when did the deceitfulness and madness of daemons fall under contempt, save when the Word, the Power of God, the Master of all these as well, condescended on account of the weakness of mankind and appeared on earth? When did the practice and theory of magic begin to be spurned under foot, if not at the manifestation of the Divine Word to men? In a word, when did the wisdom of the Greeks become foolish, save when the true Wisdom of God revealed Himself on earth? In old times the whole world and every place in it was led astray by the worship of idols, and men thought idols were the only gods that were. But now all over the world men are forsaking the fear of idols and taking refuge with Christ; and by worshipping Him as God they come through Him to know the Father also.
Anyone, too, may put what we have said to the proof of experience in another way. In the very presence of the fraud of daemons and the imposture of the oracles and the wonders of magic, let him use the sign of the cross which they all mock at, and but speak the Name of Christ, and he shall see how through Him daemons are routed, oracles cease, ad all magic and witchcraft is confounded.
Who, then is this Christ and how great is He, Who by His Name and presence overshadows and confounds all things on every side. Who alone is strong against all and has filled the whole world with His teaching. Let the Greeks tell us, who mock at Him without stint or shame. If He is a man, how is it that one man has proved stronger than all those whom they themselves regard as gods, and by His own power has shown them to be nothing? If they call Him a magician, how is it that by a magician all magic is destroyed, instead of being rendered strong? Had He conquered certain magicians or proved Himself superior to one of them only, the might reasonably think that He excelled the rest only by His greater skill. But the fact is that His cross has vanquished all magic entirely and has conquered the very name of it. Obviously, therefore the Saviour is no magician, for the very daemons whom the magicians invoke flee from Him as from their Master. Who is He, then? Let the Greeks tell us, whose only serious pursuit is mockery! Perhaps they will say that He, too, is a daemon, and that is why He prevailed. But even so the laugh is still on our side, for we can confute them by the same proofs as before. How could He be a daemon, Who drives daemons out? If it were only certain ones that He drove out, then they might reasonably think that He prevailed against them through the power of their Chief, as the Jews, wishing to insult Him, actually said. But since the fact is here again, that at the mere naming of His Name all madness of the daemons is rooted out and put to flight, obviously the Greeks are wrong here, too, and our Lord and Saviour Christ is not, as they maintain, some daemonic power.
If then, the Saviour is neither a mere man nor a magician, nor one of the daemons, but has by His Godhead confounded and overshadowed the opinions of the poets and the delusion of the daemons and the wisdom of the Greeks, it must be manifest and will be owned by all that He is in truth Son of God, Existent Word and Wisdom and Power of the Father. This is the reason why His works are not mere human works, but, both intrinsically and by comparison with those of men, are recognized as being superhuman and truly the works of God.
