Description of the Antichrist in St. Hildegard von Bingen (1173 AD)The Antichrist will indeed be infused by the devil when he opens his mouth to teach perversity, as described above. He will destroy all that God established with the ancient and the new law, and he will assert that sɛҳuąƖ immorality and other like things are not sins at all. For he will claim that it is not a sin if flesh heats up flesh, just as it is not a sin if a person warms himself by the fire. He will also assert that all commandments concerning chastity were made in ignorance, for since one person may be hot but another cold, they ought to moderate one another with their heat and cold.
And again he will say to the faithful,
“Your law of sɛҳuąƖ restraint was established contrary to the way of nature. Is a person not supposed to be hot, when his very breath is a fire that kindles his whole body? How could he keep his cool when it’s against his nature? Conversely, what reason could a person have to refuse to offer warmth to another’s flesh? For that man who you say is your master gave you a law that goes beyond measure when he bid you to live in such a way. But I say, embrace these two paths of hot and cold, and keep each other in your warm embrace? Consider that the man just mentioned gave you unjust commands, for despite his order that people not embrace one another with such warmth, they still maintained the nature of their flesh. So see here and do not be misled any longer by an unjust teaching, for with me you get to do whatever you want or not. Your master did not set before you correct propositions; he wanted you to be like a spirit that is unbound by the flesh and cannot physically do anything. But that’s not how naturally-born human flesh was created; rather its flooded and formed by fire, because if human children weren’t created in that way, they wouldn’t be capable of physical action. So know then what you really are! For your first teacher deceived you and didn’t help you in anything. But I inspire you really to learn about yourselves and to know what you are, for I created you, and I am completely in all things. In assigning all his works to another, meanwhile, that one spoke nothing on his own because he couldn’t do anything on his own. But I speak for myself, and I can do all things by myself.”
With these words and others like them, that wretched son of perdition will mislead people, teaching them to live according to the flesh’s fiery appetite and to achieve their flesh’s every want--despite the fact that both the old and the new law encourage humans to chastity in such a way that chastity does not surpass its proper measure.
