The ReligionFacts "Big Religion Chart" is an attempt to summarize all the complexities of religions and belief systems into boxes on a single, quick-reference comparison chart. Yes, of course this is impossible. As we always warn with our comparison charts, this is no substitute for reading about religions in greater detail, talking with religious adherents, etc. But this religion comparison chart can (hopefully) be a useful and accessible way to "get the gist" of some unfamiliar groups and compare basic beliefs and practices of the world's religions and belief systems. Currently, 43 belief systems are listed.
