Daniel L. Migliore, Faith Seeking Understanding, 276.
Several features of the act of witness stand out. First, the witness is sword to tell the truth. Second, faithful witnesses draw attention not to themselves but to someone or some event distinct from themselves. Third, the need of witnesses arises from the fact that what they tell us is quite different from a general truth that can be known in advance or that is universally accessible. Witnesses attest particular events. Fourth, the act of witness is self-involving. It requires personal participation, commitment, and courage. Fifth, because the truth is often resisted, the commitment of the witness in its most solemn form may become a commitment unto death. The link between witness and risk-taking is preserved in the New Testament word martus, “martyr.” While not in itself proof that a witness speaks the truth, commitment and risk-taking distinguish what a witness does from detached observation or passive transmission of information.
