I guess it goes by interpretation if Mary was the mother of Jesus, I know Catholics, Eastern Orthodox, and Lutherans all believe that Mary was the legitimate mother of Jesus, but Anglicans, Methodists, and every other protestant off shoot believes the opposite, she was just a womb (however morbid that sounds). I believe in a mythical sense Jesus was both man and god, much like Heracles, he was certainly mortal and throughout his life he had a difficult time coming to terms with his power (thats why in the Bible he goes from being age 10 to age 30 and it skips the middle years). I think a more correct term would be to associate Jesus and Holy Ghost, Jesus is a mortal Man, the Holy Ghost is Jesus and therefore god in spirit.
