"[I]f 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."

—Athanasius, On the Incarnation
