Well as far as I can recall, "the Christians" were just one of another of bunch of folks who wanted to topple the govenerment, after they had been nice enough to let them govern themeselves, and even tried to adopt some of the gods. Must have been an interesting converstation.

Registrar: "and your God of chose is?"

Registrar: "Ok, then we put down for Nun of the Above".
