When people tell you they keep all nine of the Ten Commandments either their math skills are lacking or their logic center has shut down.
That's nothing. The New Testaments records fity commandments of Jesus, and His disciples are to "observe" them all (Mt. 28:20).
One of them is that each (at least of the men, but I would include women) is to carry a sidearm of a deadly weapon, and if one does not have the cash, to sell your extra coat to get one. Do you know how many of the disciples at the Last Supper were already armed?
Do you carry a sidearm to church? As did the Pilgrims?
