5. Again, we are taught as follows by the prophet Isaiah regarding another opposing power. The prophet says, “How is Lucifer, who used to arise in the morning, fallen from heaven! He who assailed all nations is broken and beaten to the ground. Thou indeed saidst in thy heart, I shall ascend into heaven; above the stars of heaven shall I place my throne; I shall sit upon a lofty mountain, above the lofty mountains which are towards the north; I shall ascend above the clouds; I shall be like the Most High. Now shalt thou be brought down to the lower world, and to the foundations of the earth. They who see thee shall be amazed at thee, and shall say, This is the man who harassed the whole earth, who moved kings, who made the whole world a desert, who destroyed cities, and did not unloose those who were in chains. All the kings of the nations have slept in honour, every one in his own house; but thou shalt be cast forth on the mountains, accursed with the many dead who have been pierced through with swords, and have descended to the lower world. As a garment clotted with blood, and stained, will not be clean; neither shalt thou be clean, because thou hast destroyed my land and slain my people: thou shalt not remain for ever, most wicked seed.

Moreover our Lord, who is the truth, compared the power of His own glorious advent to lightning, in the words, “For as the lightning shineth from the height of heaven even to its height again, so will the coming of the Son of man be.”[118] And notwithstanding He compares him to lightning, and says that he fell from heaven, that He might show by this that he had been at one time in heaven, and had had a place among the saints, and had enjoyed a share in that light in which all the saints participate, by which they are made angels of light, and by which the apostles are termed by the Lord the light of the world. In this manner, then, did that being once exist as light before he went astray, and fell to this place, and had his glory turned into dust, which is peculiarly the mark of the wicked, as the prophet also says; whence, too, he was called the prince of this world, _i.e._ of an earthly habitation: for he exercised power over those who
