I to was raised Catholic, left ot long long ago. What you call communion, I call ritualized cannibalism. Pagans/Witches eg don't replace male diety whith female deity - we merely balance deity as we balance to rest of our life.
If you want an example of magic, I'm a kitchen witch who does most of the baking with intent for cakes and ale. For a Lughnasah ritual once when we sliced the heavy grain loaf I made as offering we found the stick figure of a man running the length of the loaf allowing everyone to partake of the grain god & allow all who wished to take home pieces to bury in their gardens for fertility in the next year.
