Luke 8:32

(de vita Anton.) But if they have no power over swine, the evil spirits have much less against men who are made after the image of God. We ought then to fear God alone, but despise them.

They are carried violently down, for they are reclaimed not by the contemplation of any good deed, but thrust as from a higher place to a lower, along the downward path of iniquity, they perish amidst the waves of this world, shut out from the approach of air. For they who are carried to and fro by the rapid tide of pleasure cannot receive the communication of the Spirit; we see then that man himself is the author of his own misery. For unless a man lived like the swine, the devil would never have received power over him, or received it, not to destroy but to prove him. And perhaps the devil, who after the coming of our Lord can no longer steal away the good, seeks not the destruction of all men, but only the wanton, as the robber lies in wait not for armed men, but the unarmed.

(de Con. Ev. l. ii. 24.) The words of Mark, that there was a herd of swine nigh unto the mountains, and of Luke, on the mountains, do not differ from one another. For the herd of swine was so large, that they might be part on the mountain, part near it. For there were two thousand swine, as Mark has stated. (Mark 5:13.)

The multitude of unclean spirits seek therefore to be sent into the herd of unclean swine, like to themselves, for it follows, And they besought him that he would suffer them to enter into them.

Which indeed the devils demand, wishing yet longer to mix with mankind.
