Statements on the different kinds of spiritual wickednesses.
Then Germanus: We want to know what is the origin of the great variety of hostile powers opposed to men, and the difference between them, which the blessed Apostle sums up as follows: “We wrestle not against flesh and blood, but against principalities, against powers, against the world rulers of this darkness, against spiritual wickedness in heavenly places:” and again: “Neither angels nor principalities nor powers nor any other creature, can separate us from the love of God which is in Christ Jesus our Lord.” Whence then arises the enmity of all this malice jealous of us? Are we to believe that those powers were created by the Lord for this; viz., to fight against men in these grades and orders?
