Minecraft wiki entry for Building_a_metropolis, associated text: Temple Though it may seem similar to a church, it isn't the same thing. You can make a humongous temple, or a little tiny shrine the size of a sandstone well. You can have an area for training in magic (if appropriate), a way to sacrifice, a table, lava, bottomless pit, etc. Also, make sure the temple makes sense; for instance, put a god of shadows underground and a god of time and space with end stone, portals and other mysterious things. Gather players to be priests or spawn cleric villagers and give them cows and pigs to sacrifice. Or if you're slightly more brutal, and if you have captured players/criminals, you could sacrifice them to the gods. You can also design the temple after a real-life religious building, such as a mosque.
