Which clearly states that p[people can state their position about what they believe to be the "betterment of society", but points out that they do not have the authority to dictate or enforce that POV on others.

People of faith can absolutely guide their involvement in the public sphere by their beliefs. I really don't care if you and @Mendalla would have otherwise Gord. If a politician who is a believer is voting on something, for example, they absolutely have the right to base that decision on what they believe.
