Just so you know, what M M said is idiocy.
All the non-idol worshiping religions in the day were called Mystery Schools but I don't think M M is well versed enough to deal with anything but a false sound bite.

I'm aware of the religious environment of Classical Antiquity, yes; my New Testament intro class last year spent almost a month on it. I think it was an overall noxious environment in many ways, so having the options that existed at the time enumerated to me isn't going to be a good way to convince me of anything.
