The Imperial Faith is not a unified organisation, but still encompasses the faith of the Imperial people in a coherent belief structure. Most gods have their own individual temples, and their own internal hierarchy of priests and clerics, but the vast majority of smaller temples are ecumenical, offering worship to, if not all, then most of the known gods. Theology outside of some universal beliefs is not formally defined; so long as the appropriate gods are venerated in appropriate ways, then no more can be asked.
