What are Christians saying when they call the Bible the Word of God? How is that statement to be understood in relation to postmodernity's suspicion of meaning? Word and Supplement tackles these questions by bringing post-modern theory into critical dialogue with the often-neglected doctrineof the sufficiency of Scripture. The notion of the 'sufficiency' of a text, and the contrasting idea of the 'supplement(s)' which texts carry with them, together provide a sharp critical tool for analysing a variety of contemporary hermeneutical and doctrinal positions. Brought into this discussionare Derrida, from whom the idea of 'supplement' is borrowed, Barth, Frei, Fish, Hirsch, Hauerwas, Gadamer, Bakhtin, Fowl, Wolterstorff, Vanhoozer, Childs, and Warfield. Building especially on descriptions of language as action, Word and Supplement critically reconstructs 'the sufficiency ofScripture' as both a concept and a doctrine which must remain central to Christian theology and practice.
