When one reads pacifists it is easy to assume they have forgotten about sin. Pacifists tend to downplay sin and how ugly the world gets. They assume that all men are reasonable and therefore violence is never necessary. Andrew Fulford responds to this at the end of his book, Jesus and Pacifism. In this section he is critiquing Stanley Hauerwas’ critique of C.S. Lewis.
What I will note is a false assumption…the idea that all people ultimately have a good will. That is, some pacifism assumes that all violent individuals can ultimately be reasoned with, and therefore force is never really necessary. But this is simply not true, or at least we have no evidence to think it is. Violent sociopaths are people who violate this stricture: they are aware they hurt people and that what they are doing is wrong, but they do it anyway. And Scripture testifies that our experience is correct, that such rebellious people do exist…So in fact there is no good reason to assume we can always talk violent people out of their behavior, and that deep down they are all just folks like us. Sometimes they not.
Force is necessary at times because some men are so wicked that they will not listen to reason. For most of us this is as plain as the sun rising. But some pacifists cannot see this at all. I wonder if the Anabaptistic view of sin is one reason why they lean towards pacifism? That question will need to be answered another day. For now, it is clear that violent force is at times necessary.
