For what war should we not be fit and eager, even though unequal in numbers, we who are so willing to be slaughtered–if, according to that discipline of ours, it was not more lawful to be slain than to slay?
Tertullian, Church Father
Above all Christians are not allowed to correct by violence sinful wrongdoings.
Clement of Alexandria, Church Father
Love your enemies and pray for those who persecute you, that you may be children of your Father in heaven.
We ourselves were well conversant with war, murder and everything evil, but all of us throughout the whole wide earth have traded in our weapons of war… The more we are persecuted and martyred, the more do others in ever increasing numbers become believers.
Justin Martyr, Church Father
Do violence to no one, nor accuse falsely, and be content with your wages.
