Only one level higher for a temple, according to the manual.

Still mostly useful for getting rid of enemy dominion.

Actually then manual says "Preaching can only raise dominion as high as twice the level of the priest", so a H1 should be able to raise dominion to 2, 4 with a temple.
Is that right? Going from memory it doesn't seem to match when the game tells me preaching won't work.
