Pacifism vs. just-war

Whether Christians may participate in war / state violence at all (pacifist tradition: Anabaptists, Quakers, some Mennonites) or whether Christians may serve in armed forces under just-war criteria (Augustine, Aquinas, mainstream Catholic + Protestant). "Affirms" = the just-war / mainstream historic position; "denies" = the pacifist / nonresistance position. Look for "peace church", "nonresistance", "conscientious objection" for pacifism, vs. "just war", "military chaplaincy" for the mainstream position.

This doctrine distinguishes traditions but is not a boundary of orthodoxy.
