When I refer to Christians, I'm basically making reference to the Roman Catholic variety, since that is what I'm familiar with. Christians, as a rule, are less participatory in their services. They are attended with the priest presiding. All Witches are priests or priestesses and can command their own rituals, they need no blessing other than from the Gods. Christian Mass is fed to the people.
Witches feed each other.
They have only one God, we have many. Like facets of a jewel, we have a rich collection of aspects to cull from. Our Gods cross many lands, oceans, and languages. Theirs does not. I can understand the draw from one to the other, I've been there as I've stated before.
