To nudge in a wee bit, when Christ sent some of his men out he told them to buy a sword. Jesus also used violence in his attack on the men who had turned his temple into a den of thieves. And Jesus didn't tell us to free those in prison, but to visit them, though being barred from rights and languishing in prison is in its nature a violence. So the often over used "other cheek" and "die by the sword" scriptural snippets require context, in much the same way that you need context to distinguish between murder and a lawful killing in defense of your own. Christ didn't demand pacifism any more than he expected everyone to sell what they had to give to the poor.
But the poster wished to opt for lethal force.
All of Jesus's disciples were (arguably) tough people, and clearly Cephas favoured the Machaerus (spelling?), but when he actually used it on a temple servent in Gethsemane Jesus stopped him, and healed the man's wound. Clearly, even in that fraut situation Jesus was not prepared to use violence.
John's account of the Temple clearance does worry me because the timeline seems a bit jumbled there. The first accounts propose that this action happened in the last week and was almost certainly the reason for Jesus's arrest, whereas in John it was the bringing to life of Lazarus which caused the priesthood to want him arrested..... In the synoptic reports Jesus did not so much use violence as force. I have intimate knowledge of the difference between force and violence from years of thief catching, detaining..... hundreds of times I needed to use force, only a very few times was I ever so terrified that I used violence, nor did I ever set out with the intention of being violent. SWhat do you think of my separation of these two acts?
Incarceration in a prison is force..... not violence, and Jesus was not 'strong' about death penalties, as shown by his intervention in the stoning of the adulteress.
I do believe in defence. I do believe in necessary force, which can or might lead to a death, but the deliberate intention to go out and kill leaves anthing that Jesus said or did far behind, surely?
