We can talk about the land, air, and water congestion created by the Unam Sanctum but the essence of all religion and philosophy which create our traditions in law is Mat 7:12.
12 [e]Therefore whatsoever ye would that men should do to you: even so do ye to them: for this is the [f]Law and the Prophets.
Can we have just one law to follow and be fiduciaries in the standard of prudent men?
