If this sort of thing appeals to you, I highly recommend the book “Requiem” by Graham Joyce.
As well as a rather odd and riveting book, it includes many interesting takes on classical Christian theology, and brings to light some rather common sense human issues that are never acknowledged. For instance, would the bible and biblical stories have been altered by an early forming church to manipulate the tribes of Judea? He also includes some rather obscure information about an old Judean cult in which the heads were Priestesses which relived men of their sexual tensions so that they may be productive in society (a rather interesting and plausible Idea I think). In this story, Mary Magdalene is painted as one of their priestesses, exiled from the bible by casting her as a common whore. It also goes into the thought that perhaps Jesus was married.
