"It is the image of God reflected in you that so enrages hell; it is this on which the demons hurl their mightiest weapons."
Anyone seeking to live a Christian life will discover that our adversary will quickly move from anonymity to bullying and intimidation. But we have been given a wonderful gift, as Catholics, in that we have at our disposal a means to counter whatever comes, Mary, the mother of God. She is charged with the task of ‘crushing the head of the serpent’ (Gen 3:15).
Protestant churches have been robbed of this knowledge and struggle on without this important heavenly help, perhaps not understanding why the Lord delegated in this way.
Fr Amorth, a prolific exorcist from Italy, noticed that whenever he invoked the name of Mary during an exorcism the person became more agitated and violent; having authority over the evil one, he questioned him about it.
He asked why he seemed more afraid at the name of Mary than the name of Jesus Christ: He replied that ‘I am more afraid when you say the Madonna’s name, because I am more humiliated by being beaten by a simple woman, than by Him..’ Her power over him is such :- “Because she always defeats me, because she was never compromised by any taint of sin!”
It's analogous to a school bully who terrorizes everyone and is then laid out cold by a punch from the smallest girl, in front of everyone. God makes his humiliation fitting to his pride.
When Fr Amorth questioned further it was revealed that ‘every hail Mary makes hell tremble’ and the most noteworthy point I think was that ‘if Christians knew the power of the Rosary, it would be the end of me!’
No wonder the greatest saints were champions of the Rosary; with this weapon we can protect ourselves and Our Lady can vanquish the enemy.
