This revised version includes a new essay on the contemporary history of integral mission, a history that began with the Latin American Theological Fellowship, progressed within the Lausanne Movement, is bearing fruit globally through the Micah Network, and challenges evangelicals to address the major issues of our day. By almost any measure, a bold and confident use of the Bible is a hallmark of Christianity. Underlying such use are a number of assumptions about the origin, nature and form of the biblical literature, concerning its authority, diversity and message. However, a lack of confidence in the clarity or perspicuity of Scripture is apparent in Western Christianity. Despite recent, sophisticated analyses, the doctrine is ignored or derided by many. While there is a contemporary feel to these responses, the debate itself is not new. In this excellent study, Mark Thompson surveys past and present objections to the clarity of Scripture; expounds the living God as the Guarantor of his accessible, written Word; engages with the hermeneutical challenges; and restates the doctrine for today.
