Supposing Jesus had walked the earth in the 20th Century, and had faced a firing squad for his execution, instead of being crucified.
Then the gun – instead of the cross – would be the Christian symbol. Churches would be having a machine gun placed prominently everywhere. Christians would hang pistols or revolvers around their necks.
Pastors and priests would often say such things as “Carry your own machine gun” or “Shoulder your own artillery” in church services. There would be mass shootings every Good Friday, especially in the Philippines.
When praying, instead of making the sign of the cross, Catholics would mime pointing an invisible pistol against their temples – ready to blow their brains out. The pope would regularly mime pointing a rifle at the huge congregations. Or an RPG launcher.
Cemeteries would be full of machine and sub-machine guns: Hotchkiss, LSATs, Ultimax, Bizon SMGs, Daewoos, and so on. Huge, rotary cannons would adorn churches spires – M61 Vulcans, GAU-Avengers, and the Gryazev Shipunovs.
Interestingly, all this would be considered normal… and pious. In fact, any criminal bearing a gun would be getting an initial benefit of doubt – he could be a devout Christian, after all. And so it would be, that occasionally, a gun-wielding robber would be proclaiming, loudly, thus:
“I’m not a Christian. I’m a heartless thief. Stick your hands up!”
