I am going to chime in here: The issues involved here are complex, and speaking frankly, in some ways equally affect Catholics and Adventists.
We both operate schools at all levels of education. Every employee in those schools has a potential impact on the students. From that perspective, all, to include janitors as well as teachers of history, my rightfully be required to be members of the sponsoring Church.
I do not know if the Catholic Church has ever owned either a gasoline station or a supermarket. However, the SDA Church has owned such. Those were intended to serve the public at large. I am not certain that a reasonable case could be made for a requirement for all employees to be members of a specific denomination.
The issue of hospitals is important to both Catholics and Adventists. Hospitals are owned by both Churches. Differences exist between how Adventists and Catholics want to run their hospitals. Yet, each may have a religious component to the services that they provide. The problem is that the government determines whether or not a hospital can be established in a specific location. So, if a hospital is allowed in a local area, that has religious restrictions as to some care, no other hospital may be allo0wed in that area and only limited clinical services will be provided.
All I am saying is: Some issues of religious liberty do not have easy answers.
