I have been thinking about a religion to join. After some research this is my result:
Evgenism - state religion of Carelia, little content
Evgenism, no official support, nor is a lot of Carelia a part of the religion. Also, you clarify it as state religion but it is in progress on changing that, which you could be a part of if you joined. All active members will receive power in the religion and currently the most talkative of the week gets 25 gold. We have temples in CE, Caergoth, and obviously Carelia so don't think you must travel to Carelia to join.
