What would be the implications if a learned woman became an evangelist and her writings were integrated into the Bible? Would that effect the marketability of Christianity, and if it does retain the same amount of influence, how would this effect church hierarchy and the church's view on women? I don't want this female "Paul" to have a particularly feminist agenda, but more along the lines of Paul, either as a supplement or as a replacement, that won't really change the fundamental message of Christianity besides the fact that it is a woman preaching it.
How would Rome view Christianity in this context? I know women and slaves already were drawn to the religion because it had egalitarian concepts and offered empowerment, but if a woman was a "Church Father" then would Rome be even harsher in persecuting it? Would an emperor even think of converting, and what events would have to transpire for this Church Mother's works to be included in Biblical canon? Would bishops be of both sexes, and would monasticism take root in the same way it did OTL? What would be the difference if this Church Mother replaced Paul in significance versus if her writings were a supplement to his writings?
