From the Social Principles of The United Methodist Church:
165.C War and Peace
We believe war is incompatible with the teachings and example of Christ. We therefore reject war as an instrument of national foreign policy. We oppose unilateral first/preemptive strike actions and strategies on the part of any government. As disciples of Christ, we are called to love our enemies, seek justice, and serve as reconcilers of conflict. We insist that the first moral duty of all nations is to work together to resolve by peaceful means every dispute that arises between or among them. We advocate the extension and strengthening of international treaties and institutions that provide a framework within the rule of law for responding to aggression, terrorism, and genocide. We believe that human values must outweigh military claims as governments determine their priorities; that the militarization of society must be challenged and stopped; that the manufacture, sale, and deployment of armaments must be reduced and controlled; and that the production, possession, or use of nuclear weapons be condemned. Consequently, we endorse general and complete disarmament under strict and effective international control.
