John 14:30

(ix. de Trin) He next alludes to the approach of the time when He would resume His glory. Hereafter I will not talk much with you.

(Tract. lxxix. 2) i. e. the devil; the prince of sinners, not of creatures; as the Apostle saith, Against the rulers of this world. (Eph. 6:12) Or, as He immediately adds by way of explanation, this darkness, meaning, the ungodly. And hath nothing in Me. God had no sin as God, nor had His flesh contracted it by a sinful birth, being born of the Virgin.

But what says He next? "Hereafter I will not talk much with you; for the prince of this world cometh;" and who is that, but the devil? "And hath nothing in me;" that is to say, no sin at all. For by such words He points to the devil, as the prince, not of His creatures, but of sinners, whom He here designates by the name of this world. And as often as the name of the world is used in a bad sense, He is pointing only to the lovers of such a world; of whom it is elsewhere recorded, "Whosoever will be a friend of this world, becomes the enemy of God." Far be it from us, then, so to understand the devil as prince of the world, as if he wielded the government of the whole world, that is, of heaven and earth, and all that is in them; of which sort of world it was said, when we were lecturing on Christ the Word, "And the world was made by Him." The whole world therefore, from the highest heavens to the lowest earth, is subject to the Creator, not to the deserter; to the Redeemer, not to the destroyer; to the Deliverer, not to the enslaver; to the Teacher, not to the deceiver. And in what sense the devil is to be understood as the prince of the world, is still more clearly unfolded by the Apostle Paul, who, after saying, "We wrestle not against flesh and blood," that is, against men, went on to say, "but against principalities and powers, and the world-rulers of this darkness." For in the very next word he has explained what he meant by "world," when he added, "of this darkness;" so that no one, by the name of the world, should understand the whole creation, of which in no sense are fallen angels the rulers. "Of this darkness," he says, that is, of the lovers of this world: of whom, nevertheless, there were some elected, not from any deserving of their own, but by the grace of God, to whom he says, "Ye were sometimes darkness; but now are ye light in the Lord." For all have been under the rulers of this darkness, that is, under the rulers of wicked men, or darkness, as it were, in subjection to darkness: but "thanks be to God, who hath delivered us," says the same apostle, "from the power of darkness, and hath translated us into the kingdom of the Son of His love." And in Him the prince of this world, that is, of this darkness, had nothing; for neither did He come with sin as God, nor had His flesh any hereditary taint of sin in its procreation by the Virgin.

He says this because the time was now approaching for His being taken, and given up to death: For the Prince of this world cometh.
