wicca, because that's a very earth based, open minded and clear believe. Wiccans believe in a Supreme Being to reach Him/Her you can speak through other dieties under several names. Similar to the Catholics and their Saints. Wiccans do not all doubt that Jesus is the Son of God or that He was a great Teacher and Prophet, like they believe that Mohummad and Buddah were as well and nameless others. When Wiccans pray to the Mother and/or Father they are want the same things that a Christian wants and needs when praying to their God. Confession,Guidance,and Understanding. But unlike a Christian, they also take full responsability for their actions. They will not use the term "The Devil made me do it" because They do not believe in Satan. This Entity does not exist. Why? Because of the belief they hold that everything has a dual side. Light/Dark, Good/Evil, Black/White, Up/Down. No Entity causes our misdeeds. Its a failure in our Human Nature and that We must rise above it or pay the 'threefold' consequences....
If you look closely to different religions you will find multiple similarities.
If we would all just see those like minded waves and respect the ones we differ on, the world would be a much beter place!
