I'm not sure one would have to give up their faith at all to help someone else. In the example of the woman from Kentucky, I think she was wrong and furthermore, I think that her giving a marriage licence to a gay couple should not have even been a factor in her faith. The separation of church and state is law. In my profession (critical care nurse), I had to take care of people whom I strongly disagreed with their faith and its tenets. If a parent would not give blood to a child, for example, and that child was going to die without it, I would have to adhere to their wishes. Another example might be a woman having a late term abortion and I would still have to care for her, if I were a pro-life person based on my faith. IMO, I would care for a person no matter what. So the question you ask seems ..hmmmm...not irrelevant, but rather just not something I would consider.
