After what has been said, it is right for you to understand this, to set it as the beginning of what remains unsaid, and to marvel greatly: since the Savior came among us, idolatry has not continued to increase; what remains is diminishing and gradually ceasing. Greek wisdom no longer advances, and what remains of it is disappearing. Demons no longer deceive by apparitions, oracles, and magic; whenever they dare to attempt it, they are put to shame by the sign of the Cross.
On the other hand, while idolatry and everything else that opposes the faith of Christ is daily dwindling and weakening and falling, see, the Savior's teaching is increasing everywhere! Worship, then, the Savior "Who is above all" and mighty, even God the Word, and condemn those who are being defeated and made to disappear by Him.
When the sun has come, darkness prevails no longer; any of it that may be left anywhere is driven away. So also, now that the Divine epiphany of the Word of God has taken place, the darkness of idols prevails no more, and all parts of the world in every direction are enlightened by His teaching.
Similarly, if a king be reigning somewhere, but stays in his own house and does not let himself be seen, it often happens that some insubordinate fellows, taking advantage of his retirement, will have themselves proclaimed in his stead; and each of them, being invested with the semblance of kingship, misleads the simple who, because they cannot enter the palace and see the real king, are led astray by just hearing a king named. When the real king emerges, however, and appears to view, things stand differently. The insubordinate impostors are shown up by his presence, and men, seeing the real king, forsake those who previously misled them.
In the same way the demons used formerly to impose on men, investing themselves with the honor due to God. But since the Word of God has been manifested in a body, and has made known to us His own Father, the fraud of the demons is stopped and made to disappear; and men, turning their eyes to the true God, Word of the Father, forsake the idols and come to know the true God.
Now this is proof that Christ is God, the Word and Power of God. For whereas human things cease and the fact of Christ remains, it is clear to all that the things which cease are temporary, but that He Who remains is God and very Son of God, the sole-begotten Word.
