Cerimonial Faith is much better than Restless Worshippers because of the Turmoil -> Order relationship. Along with the fact that Theurgs are reasonably cheap, magically decent and have a decent amount of priestly levels, this is probably the best of both worlds. Since you can't get into a stalemate and try to push dominion unless your military (magical or normal) is strong enough for that front.

Also considering that you are probably recruiting mostly Theurgs in 2 or more castles along with Communicants, it would allow you to switch your Research engine to a dominion pushing engine.
