Discourse on the Angels or Spirits of Empires

...the prince of the Kingdom of the Greeks, and Michael the prince of nations Michael is traditionally regarded in Judeo-Christian theology as the archangel and protector of the people of Israel.. And each one of us has with him an attached adversary, whose task it is to lead us to the prince and say: "O prince—for instance, of the kingdom of the Persians—this man who was under you, I have guarded him as was necessary; for none of the other princes was able to lead him over to himself, not even that one who boasted that he had come for this purpose: to snatch men from all the inheritances of the Persians, or the Greeks, and of all nations, and to make them subjects of God's inheritance." The "one who boasted" refers to Christ, who the "adversary" views as an intruder into his territory. Christ our Lord conquered all the Princes, and crossing their boundaries, he transferred the captive peoples to himself for salvation.

These are the princes of whom the Apostle Paul also speaks: We speak wisdom among the perfect, which none of the princes of this world knew. For if they had known it, they would never have crucified the Lord of glory. original: "Sapientiam loquimur... dominum gloriæ crucifixiſſent." — 1 Corinthians 2:6-8. But the Prince—that is, the Angel of the Persians—resisted, acting on behalf of the Province entrusted to him, lest the entire people of captives be released. And perhaps, since from the first day the prophet The prophet Daniel. set his heart to understand, he was heard by God: therefore..."
