Thank God this is finally getting some traction!
‘He said to them, “But now if you have a purse, take it, and also a bag; and if you don’t have a sword, sell your cloak and buy one. It is written: ‘And he was numbered with the transgressors and I tell you that this must be fulfilled in me. Yes, what is written about me is reaching its fulfillment.” The disciples said, “See, Lord, here are two swords.” “That is enough,” he replied.’
Luke 22
The Biblical foundation for right to bear arms was originally for swords, the light arm of the day. The idea that I can have a shotgun but not a switchblade is lunacy.
Some degree of guarding (of themselves and of resources) was bidden by Jesus. The miracles on tap that kept Him and them safe were going to come to an end. And they didn’t have the bold Spirit yet that was going to carry them to witness to the point of martyrdom in many cases. When Pentecost came that game changed. I’d still say it’s OK to defend others (such as a dependent family). IMHO only of course, modern Christians have tended to be timid because an easy political environment allowed them to live relatively easy lives. Their foe was not so much assaults as complacency, and actually a more insidious foe. Christians do better against devils that are frank about trying to rob them, than against devils that pretend to give them something.
