Cooperation and mutuality produce goodwill and harmony, whereas competition for special privilege divides men into warring camps. - Kirby Page

In the first century and in the twentieth, the individual Christian must determine his own course of action in the light of the spirit and teaching of Jesus. He gave Peter, James and John no definite program or mechanism by which they could overcome slavery, idolatry, licentiousness, and militarism, and he gives the Christian of today no scheme of overcoming militarism and oppression. It is by lives lived in the spirit of human brotherhood and worship toward God that he seeks to overcome slavery and idolatry, and it is by lives of aggressive good-will and love at all times and under all circumstances that he seeks to overcome militarism and oppression.

There may be occasions when "to do unto others as you would have them do unto you" requires coercion.

The incident in the temple when Jesus used the scourge of small cords (John 2:13-17) is often cited as indicating Jesus sanction of war. The very most that can be said in this regard is that Jesus' sanctions the use of force. To say this is not proof that Jesus sanctions war War. ...If Jesus had used force in such a way as to give supremacy to military necessity, to destroy human life, to break down reverence for personality, to retaliate with evil for evil, to compel the surrender of his moral freedom, we might then well believe that he sanctions war. The use of force is one problem, the morality of war as a means to an end involves so many additional factors as to be quite a different problem. Each should be judged on its own merits.
