This has huge implications for so many people today, especially those who simply can't accept these kinds of miracles. It does raise the question of whether you can be a Christian if you don't believe any of the Bible's supernatural stories.
I don't think you have to discard all the supernatural stories. The Bible is really about what is beyond the natural. But there are other ways of understanding. For example, the Gospel of Philip, which some people called a heretical text, actually says Jesus had human parents as you and I do. His parents were Mary and Joseph. But when he was born of the spirit, he became the son of the Heavenly Father and the Holy Spirit. In Syriac and Hebrew, the spirit is spoken of in feminine forms, so metaphorically, one could speak of her as a divine mother, just as one speaks of God as a divine father. So there are Christians who didn't reject the Virgin Birth, but said wait a minute, why would you take it literally? Why don't you take it as an image for spiritual reality?
