I'm not making a pacifist argument here. I am not a pacifist and I do not defend that position. I'm just saying historically, Christians in the pre-Constantine centuries didn't defend their families and congregations with force of arms. If you think that's disturbing, you're surely not the only one.
The passage you cite certainly is not about armed defense. They said "Here are two swords" and He said "Enough!"
Oh really? What was Peter doing carrying a sword?
John 18:10 Then Simon Peter having a sword drew it, and smote the high priest's servant, and cut off his right ear. The servant's name was Malchus.
Why does the Vatican have guards?
