Deism - there is one supreme creator who is now remote from the universe. Anrelian Religion is arguably Deist, in that it believes in one long-distant creator deity although with many lesser gods
Henotheism - there are many deities which can be worshipped, but there is one supreme being above them. The imperial religion of Dor-en-Sann is a prime example.
Monism - there is one God, with many manifestations in different religions. This is a principle in Therism, though those of other faiths would consider this imperialist.
Monolatry - worship of one god, whilst acknowledging the existence of others. The majority animist and tribal religions have this philosophy.
Panetheism - the natural world is the physical manifestation of the one deity. This is a principle in Therism, as well as most animist traditions.
Polydeism - many creator gods who are now remote from the universe
Polytheism - reverence of a pantheon of gods. Anrelian Religion is fundamentally polytheistic, though may also be considered Deist.
