Okay, here's something to ponder: could Mithraism ever become the dominant religion of Rome, much like Christianity did?
Firstly, I'm not trying to continue the ludicrous argument that Mithraism was a threat to Christianity, merely that Christianity was, for a long time, a mystery cult that eventually grew to take over the Roman Empire.
Secondly, I understand that little is truly known about Mithraism, and so this may require some guesswork, assumptions, and conjecture.
Now, the Mithraic mystery cult wasn't necessarily a separate religion for many Romans, I know. But could that change; perhaps an emperor begins persecuting them and they begin boycotting the state religion? Or simply a new decree from the leadership after a vision? An eventual evolution of the cult had it continued on more prosperously?
Following that idea, as Mithraism was popular amongst soldiers, and respected by the government (such as soldiers being exempt from wearing coronets as "Mithras was their only crown"), might its spread be peaceful? Perhaps it spreads to nearly all of the military and their families before spreading to Senators and/or we have a soldier-turned-Emperor after a civil war that believes in Mithras. This could allow for its spread without being separate from the state faith, although it could still occur with that if the Roman government didn't try to persecute them further after the split.
Going along with the idea of "Mithraists are persecuted and so go against the state faith and go underground" idea, could we simply go full Constantine and have some Emperor or some soon-to-be Emperor during a civil war get a "vision from Mithras" that saves his life/wins him a victory? That could lead to an OTL situation with Christianity, where the now underground Mithraists are accepted, and even promoted, with large, fancy subterranean mithraea being built across the Empire.
So what's most plausible? Is it at all plausible? Do we simply know too little about them?
If it is plausible, what sort of impacts could there be?
