Okay this is something Im curious about. Religion in the Imperium is officially led by the Ecclesiary (spelling?), however the Imperium is a very large place and open to interpretation. I mean if you look at Christianity, it was catholisism that is lead by the Pope in the Vatican. However there are lots of philosophies of catholisism. Later on Protestantism formed and that has many variations too. Now today there are many variations of Christianity.

So does something similar occur in the Imperium? Are there many variations of Imperial religion or is it one thing that is fully the same everywhere? Would there be conflict between religious groups in the Imperium amongst themselves?
