Do a bit of research on exorcisms and you will find that the prayers the priest uses are all in Latin.
So...
All the exorcisms in Greek, Slavic, Aramaic didn’t happen? Aren’t happening today? Have you talked to the various other Catholic rites?
Listen, I love liturgy. I think the Latin mass should be available (since I am a Lutheran, I would like old Lutheran Liturgies available also). But you are sound just like the KJV only crowd.
It is one of those things I honestly don’t understand why the hatred for and against exists.
