"Render unto Caesar that which is due Caesar", etc. Most religions stress adherence to the laws of the land, except where those laws conflict with the edicts of the religion.

Not all Christians have the same interpretation. I was taught in Catholic school that this meant that everything is God's and nothing is Caesar's.
