Yes because when Jesus came to earth he used a rosary to subdue the devil. Oh wait, no he didn't, he used scripture.

So maybe the apostles used a rosary to subdue the devil? Or probably icons right? Nope, never recorded in the history of the church.

But early Christians used the symbol to cast out demons right? And they had icons of all the apostles too? Nope, didn't fucking happen, their symbol was a fish.

Being Catholic is basically like being pagan but you just slap Jesus's name in everywhere that the old gods would go. Cope harder Catholitard, the devil is more afraid of my physical body pummeling the shit out of him than he is of your rosary.

Also would like to add that holy water only works because demons are silicone based life. You could use literally any water and they would get really pissy about it and leave. The vibrations sent out when you call Jesus name annoys them, but without actually having Jesus backing you you literally can't do anything. This is why catholic excorcisms take days, weeks, sometimes months, but when anyone who was actually going to heaven even got annoyed with a demon, they just got cast out. Mary may/may not hear your prayers, but it's pretty irrelevant because you should be praying to Jesus anyway and it's disrespectful to go to anyone else.
