The reason I ask is because recently a friend was praising the concept. I was surprised at that because she has always been an ardent supporter of legislation on account of her religious beliefs. I told her it was odd because she always wanted the state to act in accordance to her religious beliefs. Her response surprised me because I had never perceived the concept in this way.
According to her the separation of church and state is purely to prevent establishment of state appointed religion. People should be free to choose faith. However, religion is not prohibited from influencing faith. In fact authority is divine ordained position and a state is expected to uphold core religious views. For me that is a contradiction because once you start upholding ones religious views, people are just free to choose for namesake but are being forced to follow one set of rules. According to her that is not the case since there is just one fundamental concept of right and wrong irrespective of faith and the state should choose right over wrong.
This was a complete curve ball for me. To me no religious or moral authority ought to dictate what a state should do. A state is an agent that is to act in a utilitarian manner to create maximum benefit for the people. It should create laws that are universal but that do not undermine ones religious belief. How does everyone else perceive the separation?
