With that being said: The USC begins with "We the people..." If you believe that God gives you the power, that is certainly your right. If you wish to vote on issues based on your religious views, that is also certainly your right. Wherever you believe that you derive that power from isn't relevant to the law. The law is only concerned with the fact that you do have that power and it must be recognized.
Oh, thou clear spirit, of thy fire thou madest me, and like a true child of fire, I breathe it back to thee.
