Tolkien-founder of new religion?

[alatar]

What would a religion based on Tolkien's works look like? What would the doctine and dogma be?

Would it be to 'live in the ways of Iluvatar' as shown by Saint Gandalf, Saint Aragorn, Saint Frodo, etc in order to avoid being sent to the...well...Void? What would the structure be - centralized or more dispersed? Is there a 'priesthood' or some other ranking of adherents, or can anyone 'speak first.' Would there be associated rituals - note that a ritual may portray an event with some significance, and somewhere down the timeline take on a completely new or different meaning.

Would the true believer have to make some kind of journey to a volcano, and throw a ring into it ("By the grace granted by Iluvatar I cast this Ring into the Fire")? Would there be some ritual where the priest points a dagger at the heart of the supplicant, who then calls on Elbereth Gilthoniel, thereby 'turning' the power of the blade away from his/her heart?

Would the Ring be a good icon?

And of course we could have a schism (most probably over Balrog's wings).
