In Christian-wiccan/paganism, Mary plays a big part.
Some sees her as the mother goddess, or the wife of Jesus and co-Saviour. I'm from the latter school
, I think that they were married, it's not mentioned in the bible as it was not deemed necessary. In the gospel of peter it is said that Jesus loved Mary Magdalene more than anybody else. It could imply that they were married.
Also if one look thru the gospels One can see if something major happened in Jesus ministry Mary Magdalene was there. She was there when He was Died on the cross, She saw the grave being shut, She was first to find the grave unoccupied, Jesus appeared first to her, she was first to be send out to tell everybody that Jesus was risen.
