"Moreover, in order that we may be aroused and exhorted all the more to carry this out, Scripture makes known that there are not one, not two, nor a few foes, but great armies, which wage war against us. For Mary Magdalene is said to have been freed from seven demons by which she was possessed [Mark 16:9; Luke 8:2], and Christ bears witness that usually after a demon has once been cast out, if you make room for him again, he will take with him seven spirits more wicked than he and return to his empty possession [Matt. 12:43-45]. Indeed, a whole legion is said to have assailed one man [Luke 8:30]. We are therefore taught by these examples that we have to wage war against an infinite number of enemies, lest, despising their fewness, we should be too remiss to give battle, or, thinking that we are sometimes afforded some respite, we should yield to idleness. But the frequent mention of Satan or the devil in the singular denotes the empire of wickness opposed to the Kingdom of Righteousness. For as the church and fellowship of the saints has Christ as Head, so the faction of the impious and impiety itself are depicted for us together with their prince who holds supreme sway over them. For this reason, it was said: "Depart, ...you cursed, into the eternal fire, prepared for the devil and his angels" [Matt. 25:41]."
