[35] And Jesus said to them, “When I sent you without money bag, knapsack, and sandals, did you lack anything?” So His disciples said, “Nothing.”
[36] Then He said to them, “But now, he who has a money bag, let him take it, and likewise a knapsack; and he who has no sword, let him sell his garment and buy one.
[37] For I say to you that this which is written must still be accomplished in Me: ‘And He was numbered with the transgressors.’ For the things concerning Me have an end.”
[38] So they said, “Lord, look, here are two swords.” And He said to them, “It is enough.”
This passage has me confused. Especially the part with the sword. In the gospel of John, and I think the others too, He never commands them to get swords. When Peter cuts off the ear of the servant, it seems like the sword comes out of nowhere. But Luke implies Jesus commanded His disciples to carry swords and fight when needed. Even His rebuke later on, of the disciple who cut off the soldiers ear, is as follows:
Luke 22:49-51
[49] When those around Him saw what was going to happen, they said to Him, “Lord, shall we strike with the sword?”
[50] And one of them struck the servant of the high priest and cut off his right ear.
[51] But Jesus answered and said, “Permit even this.” And He touched his ear and healed him.
From this it seems like the disciples weren't in the wrong for having swords, but for using them at the wrong time. He did command them to get swords in the first place or at least make it okay for them to have them.
Matthew 26:52
“Put your sword back in its place,” Jesus said to him, “for all who draw the sword will die by the sword."
This seems to be a warning against using weapons. Not just that the disciples used it in the wrong place [like Luke suggest] but that having them in general is unwise. Which makes me wonder, does that passage in Luke fit the narrative of the other gospels? So what exactly are these passages conveying concerning weapons and fighting—considering the great length Jesus went to in Matthew 5 to proclaim pacifism towards evil?
Which then I have to ask: is it okay for Christians to keep swords [weapons in general]?
