First and foremost, to err is human. She should be forgiven.

However, I highly doubt that people involved in the photoshoot didn't know about the controversy it could stir. Of all the items out there, you had to pick something that had religious value, why? Because you wanted to stir things up for publicity. We will just do it and if this catches steam, as we planned, then we will immediately apologize. It kinda worked as well, nobody knew who she was before this incident - while many still don't, some will know have known her. Any publicity is a good publicity.
