===Monotheism===
Monotheism is the probably the most familiar to western readers. There is a singular god that made everything, he is almighty or all powerful, yadda yadda. IRL, this mostly means Islam, <s>DA JOOZ</s> Judaism, and Christianity, though Sihkism also fits this description. Monotheistic faiths can be surprisingly diverse on their belief systems and practices and ways in which they practice their faith, though they generally tend to agree with the overall sentiment of there being only one god.  That's one thing even Catholics and Sunni Muslims agree on.

Culture can also have a deep influence on a sect of monotheistic faith. A prominent example of this is the Baptists in the United States, who generally don't drink for what would seem are religious reasons, but there is no actual scripture that explicitly forbids alcohol (it's usually done as a precaution against drunkenness, which is condemned in Scripture). Much as the Ecclesiarchy is very flexible in what it allows, so do many monotheistic faiths, so long as the general sentiment is still true to the overall message of Scripture.

A great example of Monotheism is the Imperial Cult, which worships the God Emperor, and venerates the Space Marines as his Angels of Death, which is pretty much just analogous to medieval Catholicism (tl;dr: the largest branch of Christianity. Their leader wears a funny hat too!)
