paganism is an umbrella term for nature based religions - just like christian is an umbrella terms for religions that believe in christ

wicca - is a modern (1954) religion

witchcraft - is an encompassing term for one of the pagan paths

not all witches are wiccan and not all wiccans are witches AND not all witches or wiccans are pagan and not all pagans are witches or wiccans (you confused yet )

take a look at a lot of the catholic rituals - they are VERY pagan like

paganism is about balance & duality, they worship the God and the Goddess, etc - there is a balance in everything

some believe in a threefold law - that everything you do comes back at you threefold (so 3 times)

spellwork - well for me it works when it is supposed to, sometimes it doesn't work, sometimes it does. It is very much like the xtian concept of praying - you ask for what you would like to manifest in your life. For most pagans (who do spellwork - not all do), there is preparation before doing a spell, it helps build the energy and focus the intent of what you would like manifested.

I'll come back and post more when my head is less fuzzled from the ritual on friday night.
