The less sure we are of the truth of our religious convictions, the more we consider them immune from public scrutiny. But in the process we lose what seems essential to their being true, namely that we be willing to commend them to others. For the necessity of witness is not accidental to Christian convictions; it is at the heart of the Christian life. Those convictions cannot be learned except as they are attested to and exemplified by others. The essential Christian witness is neither to personal experience, nor to what Christianity means to “me,” but to the truth that this world is the creation of a good God who is known through the people of Israel and the life, death, and resurrection of Jesus Christ.
Without such a witness we only abandon the world to the violence derived from the lies that devour our lives. There is, therefore, an inherent relation between truthfulness and peacefulness because peace comes only as we are transformed by a truth that gives us the confidence to rely on nothing else than its witness. A “truth” that must use violence to secure its existence cannot be truth. Rather the truth that moves the sun and the stars is that which is so sure in its power that it refuses to compel compliance or agreement by force. Rather it relies on the slow, hard, and seemingly unrewarding work of witness, a witness which it trusts to prevail even in a fragmented and violent world.
