I'm interested in this too.

I've heard an account, that some Byzantine queen-consort was told by a soothsayer that she (the queen) in her pervious life, was a witch.

So the queen asked/persuaded the king to remove this from Christianity.

Lots of evidence early Christians believed in it just a sample:

Your earlier comment generalises a bit too far though. Some early christians is not the same as early Christianity. Interesting fact nonetheless.

I admit I’m not too well versed in the literature but I think I learned in world civilization class that one of their gods came back to life (and opened its own tomb and walked out) after ritual execution by the Romans. That puts reincarnation at the center of the story.

Resurrection is different thing than reincarnation though.

Sorry, I am not well versed in the finer subtleties of the domain's jargon.

It's not really domain specific jargon, it's just the dictionary definitions of the words.
