They have a good idea about their problem, that they'll lose their parking spaces and in turn probably lose parishioners. I think claiming that it's an assault on their practice and freedoms of religion is an extreme stretch of the constitution though.

I would hope for a solution, perhaps a grocery store or similar in the area that would allow them to use the back of their parking area for a small fee and a shuttle bus would work? Of course at the same time I think businesses and religious institutions should have been consulted during this idea phase.
