Actually, what am I saying, my character on Far East Island was an elder priest of MAE, and made fairly substantial additions and changes to the faith. New rituals and ceremonies, new religious iconography, new theological doctrines...
It is harder to work with existing material (while respecting others' previous work) than to create your own theology from scratch, I agree. On the other hand, there's much more motivation to engage with an existing body of theology and worshippers.
Edit: And this was all long after the founder, and subsequent dignitaries, had basically lost interest.
