Rome was full of mad religious cults at the time-elagabalus and his worship of the sungod was just an example. I fancy that this may well discredit christianity in a way, making it seem like yet another crackpot eastern cult that would probibly lead to severus being assasinated ( as OTL) and christianity being sidlined once again. Then again, it may lead to more exceptence and christians playing a more major role in the upcomiong 3rd centuary crisis. The thing is, with Althistory its difficult to imagin people faith, or reaction to a new faith. Thats the problem with the new TL i've just started on no constantine and boy, thats going to become confusing.
Whatever though, i doubt it will lead to an early conversion of an emperor and early standardissation of christianity. So not much in the long run-but with religious butterflies......well anything could happen.
My TLs:
Ad vindictam deorum: The assasination of Constantine
and A brave new world: Dinosaurs not quite wiped out...E]
The crackpot cult is actually what partially inspired me. I'm not suggested Alexander convert or makes Jesus Supreme God of the Roman Pantheon (though Jesus King of the Gods sounds awesome
