Religious prefernce is fine, but if it interferes with the performance of her job then she has an obligation to step down/quit.

There is the issue of the job being an appointment hence not able to be fired. However there was an obilgation on the part of who ever appointed her to demand she perform the job assigned or relinquish the position.

There is no doubt she knew how this was going to end up. Where was the supervision/responsible management?

To allow it to become a media circus is in keeping with the sensationalism allure of the day.

There is more to the story not known.
