According to a report, Tony Perkins, the head of the Family Research Council claimed in a fundraising letter, "not only did Jesus tolerate weapons, he instructed His disciples to buy them!"
His reference is Luke 26:38. I will not go into great detail about how absurd it is to pick one passage out and make it mean something that goes against all the other references Jesus makes to peacemaking, etc.
Look at the whole passage, what is Jesus saying. Armed rebellion? Weapons for everyone?
I rather like this prayer instead of Perkins idea:
Eternal God, in whose perfect kingdom no sword is drawn but the sword of righteousness, no strength known but the strength of love: So mightily spread abroad your Spirit, that all peoples may be gathered under the banner of the Prince of Peace, as children of one Father; to whom be dominion and glory, now and for ever. Amen. (from the Book of Common Prayer)
