Anyone working on the boundary between a postconservative evangelical theology and the best of the more traditional theologians, needs the wise counsel of Kevin Vanhoozer. A good place to start in his 2002 work, First Theology: God, Scripture, & Hermeneutics. Vanhoozer's concern is for fidelity to the "sensus scripturalis." He writes, "I am…advocating a distinctly Christian and theological, which is to say trinitarian approach to biblical interpretation that begins by recognizing God as a triune communicative agent and Scripture as the written locus of God's communicative action" (p. 38). In a footnote, he instinctively adds, "Jesus Christ is, of course, the Word of God made flesh. The life of the incarnate Jesus therefore is God's communicative act as well. The point is, however, that one can begin with Christ only by attending to the apostolic (divinely authorized) testimony about him."
Whether or not one agrees completely with Vanhoozer's use of speech-act theory [and I understand he may have some qualifying thoughts himself], his work is always astute, careful, and a joy to read.
