Just some ideas on types of religion to toss into the discussion...
Ressurrective: The religion is based on the idea that a Person who once lived and died will eventually come back in a glorified form of their original self. Those who believed in the Perfect Person and died (especially as martyrs to the faith) will be ressurrected along with the Person. Examples include Arthurianism (the "Once & Future King"), Christianity, Elvis-worship and the Cult of the Ancients ("Hail to thee, o Grandfather divine!").
Philosophical: A Great Person once lived who figured out all the secrets to living the Perfect Life. Current followers not only try to practice the life-style, but they also try to emulate the Great Person in every way. Belief in an afterlife is not mandatory, and may even be discouraged. Examples include Buddhism, Gandhi-ism, Saganism ("We are Star Stuff!"), and other cults of personality ("Strephon Lives!").
Reincarnative: Only those souls that reach perfection never need to reincarnate. Between lives, souls spend hundreds of 'material' years contemplating their activities. After they've assimilated all their previous experiences, they can come back. Karmic sects believe that one 'good' life deserves another, and that a 'bad' life means coming back as a lower life-form. Deterministic sects believe that the sequence of lives is already laid out from the moment the soul is created. Non-Determinist sects believe that souls can choose some, if not all of their next lives' characteristics.
Animistic: Everything that can be measured embodies a 'spirit'. These spirits sometimes communicate with ordinary people, giving them insight into current situations or probable futures. People can placate or bribe these spirits for favors. ("No, dear ... that oak tree is an incurrable gossip. Go tell your troubles to that elm over there.")
Materialistic: Only that which can be perceived through the seven physical senses exists, or with measuring devices that translate otherwise undetectable events into forms that human senses can perceive. There is no "Afterlife", no god, no eternal reward (or punishment). Also known as the Cult of Skeptics ("Hmph! Evidence, Please?")
Humanistic: Only humans matter. The trouble comes in when humaniti is so narrowly defined that concepts of a "Master Race" become dominant, especially when those definitions are based on purely cosmetic differences. Confusion arises due to the fact that beings of each sentient species may consider only members of that species as "human" and all others as "non-human" ("K'kree first! Kill the meat-eaters! Kill the abominations!").
