Yes, I believe that violent revolution is justified by [a modified version of] "just war" theory. As for my church - well, I travel around quite a lot at this point, so I don't have any single church that I always attend. I was baptized Orthodox, but my personal beliefs are more of a mixture of Orthodox/Catholic and Protestant views. I've attended churches belonging to several different denominations.
As a Christian, do you believe in the "just war" doctrine as a theological justification for revolutionary violence? What 'church' do you exactly belong in real life?
