One of my favorite websites is Belief.net It's a treasure trove of information about all the major worlds religions. It's an especially good place to go if one is searching for others who may fall within their same belief system. My favorite part of Belief.net is the Belief-O-Matic. It's a fun test to take in which you answer a series of questions about your beliefs. Once done, the Belief-O-Matic will provide a list of approx 25 religions or belief systems and will give you a percentage which shows how closely your beliefs are in line with those. Here's the top five that were on my list:
As you can see, Belief.net also provides links to each all the religions you match so you can read and understand what their belief system is. My results aren't surprising because I am a Unitarian Universalist who practices Buddhism and I've always had a huge respect for the Quakers.
