What would be the effects of a major Messianic religion having a female Messiah? How, where and when would this religion arise? And how successful would it be at proselytising? My opinion is that such a religion could actually be quite successful, much of Europe's pre-Christian religion was based on the worship of a Mother Goddess, which, in OTL, was rehabilitated into the Cult of Mary - a female Messiah could possibly fill that gap more easily?
Thoughts?
