The following comes from Aleteia:
Satan hates the Blessed Virgin Mary. In fact, he has been doing everything in his power to discourage devotion to her and instill hatred for her for two millennia. Have you ever noticed that it is Marian dogmas and devotions that stir the strongest reactions in those who reject the Church? Even some good Catholics are embarrassed by devotion to our Lady, and they feel we should not be too extreme in our veneration of her.
Perhaps you, too, have wondered why the Church holds the Immaculate Virgin in such high regard. Perhaps you have wonder why God has chosen to use her in the work of redemption. Today, I’d like to take a look at why the devil hates the Blessed Mother so much, and why we should be her devoted knights.
SHE WILL CRUSH YOUR HEAD
The scene is the garden of Eden. The characters are God, the serpent, Adam, and Eve. The devil is smirking in triumph. He has just deceived Eve, and through her, Adam. Oh, he is proud of himself. You can almost feel the demonic pride in destruction, for he has successfully marred God’s handiwork of creation, and dragged human beings —f or whom God has a special love — into death and misery.
God has appeared on the scene to clean up the mess, declaring the tragic curse that has arisen from sin, but also to proclaim the protoevangelium, the first hint at the Gospel and the devil’s doom.
God starts by addressing Satan, telling him he is going to eat dirt for the rest of his days. Then he reveals something that makes Satan cringe in horror — his ultimate defeat will come at the hands of a woman.
And I will establish a feud between thee and the woman, between thy offspring and hers; she is to crush thy head, while thou dost lie in ambush at her heels (Genesis 3:15, Knox)
Now, scholars argue about whether or not the pronoun is masculine or feminine in the sentence, “She is to crush thy head” — that is, whether it refers to the Virgin Mary or Jesus Christ. But I’m going to let you in on a little secret: it doesn’t matter. You see, Jesus is going to crush Satan through Mary. She is the instrument Jesus is going to wield when he destroys his ancient enemy.
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.
You see, Lucifer was originally God’s finest achievement. He was more beautiful, more powerful than all the other creatures that God has made. And as we all know, it went to his head. He was so gorgeous, so mighty that he really thought he could be better than God. The defining marks of Satan are pride and envy of the Almighty.
