It's dystopian sci-fi based on England though. The later lore is irrelevant, that's when it started turning into crap, especially around the later 2000s.
Here's the original from 1987's Rogue Trader:
""It is the 41st Millennium. For more than a hundred centuries The Emperor has sat immobile on the Golden Throne of Earth. He is the Master of Mankind by the will of the gods, and master of a million worlds by the might of his inexhaustible armies. He is a rotting carcass writhing invisibly with power from the Dark Age of Technology. He is the Carrion Lord of the vast Imperium of Man for whom a thousand souls are sacrificed every day, so that he may never truly die."
Definitely a Jesus figure. And a pretty subtly done one.
