Bible criticism is fairly recent. It had to be.
Maybe criticism of the 'entire' Bible - since the Bible as it stands in its current form is fairly recent, but criticism of individual books of the Bible, including some that were never allowed to be published as part of the Bible is not new at all - I don't know where you get your facts. Also criticism of the Bible today isn't punishable by death. Perhaps you think it still should be?
Anyway, yeah, right, whatever you say since you obviously know a lot more about Paganism and Christianity and ancient history and the Church than anyone else here.
I know you directed the question to Sirona, but if Christianity is based on ancient Pagan myths, you asked, why would she or anyone else not embrace it? I ask why embrace the copy when you can embrace the original?
