I think anyone who hasn't faced a pregnancy they weren't ready for (married or not) has no right to criticise that facial expression. Its an awful situation to be in, even now. Particularly if you don't agree with or have no access to abortion.

Mary was young, living in a society which would not have looked kindly on the situation (and I've seen or heard several reasonable and informed interpretations of the sort of thing that might have happened), and probably frightened. Even if you believe the bits about the visit from an angel, and even if she believed she was chosen in whatever way, there would have been human moments of doubt and self questioning.

She may or may not have been formally betrothed to Joseph by this time - the stories are too vague for us to know at this distance. That would have helped a bit, but not much.

I hope it helps the church in question. It certainly makes me think. And I do like some of the comments.
