Note: If you are trying to make an altar for Priest of a different religion, i.e. you are a black lighter and your priest is Vynora, you can build the altar, and have your priest put the last piece of the altar on by unclicking faithful and attaching the last piece. Works for wooden and stone altars. Underground altars will still give their bonuses above ground, for example, underground altars will spawn mycelium above ground, however you will not receive the domain message moving through these underground altars.
If you desecrate your deities deity's altar you stop following that god and have your faith and favor reset to 0. Excorcism xp is gained. The altar is removed from the game.
