Sort of along the same vein...
Years ago, I started to read The Moon Under Her Feet
by Clysta Kinstler but never finished it because the person I borrowed it from wanted it back (she was moving or something). But it was good and real popular among my circle of women (Wiccan) friends. I might pick it up again.
Here is the review/summary on Amazon:
The Moon Under Her Feet
"This feminist retelling of the conception, birth, life and death of Christ as narrated by Mary Magdalene may cause some uproar in Christian circles. Yeshua (Christ) is born to Almah Mari (the Virgin Mary) after her union in Sacred Marriage at the Temple in Jerusalem with an unblemished man who kills himself as a sacrifice for his people. Later Mari Anath becomes Magdalene, or High Priestess of the Goddess, and assumes co-rule with Jehovah, succeeding Almah Mari. Mari Anath follows Yeshua in the years of his ministry, despite objections from some adherents who call her harlot because they oppose the double worship of the Goddess and Jehovah and the equality of sexes that relationship implies. But days before the crucifixion, when Yeshua sacrifices himself, he and the Magdalene are united in Sacred Marriage in the Temple before the people. Mari Anath gives birth to Yeshua's daughter Anna after she and Judas (who is The Christos's twin brother and betrays him at his behest in order to fulfill the prophesy) flee to Gaul to make a new life. First novelist Kinstler, a professor of philosophy, mines the literature of myth to make this lyrically written interpretation plausible. She provides notes and a bibliography to buttress much of her tale. "
