As far as I know, it does not matter. Throughout the application process religion was never brought to my attention, for that matter I was not asked my religious affiliation. The concerns of the adcoms are MCAT, GPA, community service, volunteering, shadowing, etc. I took evolution, and it was never mentioned in my interview or otherwise. They focused more on the grades of the core science and advanced (3000-4000+ level) science classes.
WCUCOM does seem to consider other factors as to whether or not you will be a good fit at the school, but I felt they were more concerned with how I carried myself as a person rather than any specific religious affiliation.
Overall my application experience was enjoyable compared to other schools. Best of luck!
