Just pointing out that Satan does not really cast out satan ... So paganism and the mystic practices remain in the catholic church til today and are so much a part of it that catholics do not even notice anymore.
Just pointing out that you seem to have no clue as to what a pagan practice is compared to a Christian one and what Christian Mysticism is.
Pagan had sacred books like Scriptures too.That would make Bible reading a pagan practice borrowed by Christians according to your ideas. I could come up with all sorts of similarities to this and relate paganism to protestantism as well.
The atheist use this stuff all the time to deny there is a God.
Do you really want to go there with this?
