My son in law is Catholic and neo pagan. I think it is very possible to be both.
Jesus was the perfect Wiccan:
He esteemed diety, he had 12 disciples, thus having the perfect coven of 13.
He performed miracles (magic).
He said that you could move mountains if you have faith the size of a mustard seed. Wiccans believe intent is very powerful.
He said to treat others as you would want to be treated, you reap what you sow.This is close to "do what you will an it harm none"
Oh, and the tarot and Kabbalah are very tied to the Bible, at least to Solomon.
YHWH is very important in magick.
