It came up in the comments on Elizabeth Esther’s post, so I felt I ought to write something about this belief. It’s not actually a belief that Mary gave birth to Jesus and then God restored her hymen, though I frequently saw it characterized that way in the comments. Rather, it’s a belief that Mary gave birth without pain and without any physical damage to her body, including her hymen.
It’s primarily a theological point. As I understand it, many have seen in Mary’s ‘yes’ to God the beginning of the healing of creation. And since one of the things described in Genesis 3 as a result of our mortality is that ‘in pain you shall bring forth children’, Jesus being born without pain or physical damage is seen as one of the early signs of that healing and restoration.
I tend to disagree, but not because I find the concept incredible. After all, how is such a delivery any more incredible than a virginal conception? Rather, I lean toward a different theological perspective. Jesus became flesh, or sarx, which means he assumed everything it means to be human in our mortal state. And so I believe he was born as we are born. The healing and restoration of all creation flows from him, but he began life fully and utterly one of us.
Ultimately, though, I think we all have to confess we have no way to know which is true.
