Shadow,
There is no religious requirements to join the freemasons. The only requirement is the you believe in a "Supreme Being". This is a fraternity wide requirement, and is stated on the petition you must sign.
Freemasonry, being a worldwide fraternity, individuals from all walks of life, as well as ALL religions are members.
The only masonic body that I am personally aware of that requires you to be a christian is the "Knights Templar" As these were the christian soldiers who were said to have vowed to protect the chalis and the scrolls of ancient.
If you elect to join the fraternity, you can speak with other members of the lodge you are wishing to become a member of.
Religious disputes are never suffered within the lodge, as religion is never discussed within the lodge. I will here remark however that every "Regular" stated meeting is started and ended with a prayer. This is for your information, I want to make sure that if you are devout in your "Pagan" religion, that it won't become a hardship for you.
Best of luck and keep us posted of your progress please.
Also, welcome the forum, I hope you enjoy your stay.
