With that in mind, it is just as legitimate to say, “he will crush your head” as it is to say, “she will crush your head.” It’s kind of like telling an armed assailant, “One more step and I will shoot you” and “One more step and my .44 magnum will blow you away.” They are both true statements.
So why does being defeated by Mary pain the devil so much? Why does God want to use Mary to defeat Satan? I’ll explain.
“He has put down the mighty from their seat…”
The devil hates, I mean he loathes the fact that his ultimate defeat will come at the hands of a lowly handmaiden. In a way, his proud heart could handle being defeated by God himself because he’s almighty and omnipotent. But being crushed by a little Lady from Nazareth? The thought is absolutely humiliating. It drives him crazy. For if there is one thing the most proud creature in all of creation hates, it is being humiliated.
Satan finds his defeat by the Virgin Mary humiliating because she is a woman, and women are the weaker sex (1 Peter 3:7), and he despises weakness. He loves nothing more than to see women abused, degraded, and objectified. Not to mention that our Blessed Lady is a human, and Satan hates humans because we have bodies, and he is a pure spirit that thinks bodies are disgusting. But there’s another, more profound reason Satan hates being defeated by Mary: She is his replacement in heaven.
