Christians may carry out their protests with people who hold different beliefs, so long as they agree on the objectives and the means. Their stance ought to be to work with others when they are right and part from them when they go wrong. At all times they should boldly witness to their identification with the way of Jesus and the gospel of salvation through Christ. Spoken and written opposition to militarism and war can be powerful expressions of love and concern for our fellow human beings. The state may, of course, reject anti-war statements and go as far as to prosecute those who make them.
Some people escalate their protests, even to the point of engaging in acts of destruction.
Such action undermines the Christian message of peace. While Jesus' teaching stands in opposition to all evil, he and his disciples rarely challenged institutional evil directly. Jesus practiced an ethic of peace but we do not read that he told the Roman soldiers to leave their profession. Some Christian responses to war Pray for peace and for people in government. Even in honourable professions and businesses, do not exploit the tragedy of war for personal gain.
