Reality, Interpretation, and Proclamation: The Task of Christian Semiotics according to Augustine’s De Doctrina Christiana

Andrew Cheuk Kei WONG

　　Attention to homiletics is usually limited to the biblical exegetical task and sermon design. For Christian preaching to be true to its task, it requires, however, a lot more than this. This article investigates Augustine of Hippo’s understanding of preaching by focusing on De doctrina christiana (doctr. chr.), and proposes that ancient semiotics provides an excellent starting point for elucidating his conception of a preacher’s task. After demonstrating the rhetorical context of doctr. chr. and emphasizing the implicative relation between signs and things in ancient semiotics, the article presents Augustine’s understanding of the task of Christian semiotics—that preaching is the overall purpose of a process composed of the three interrelated stages of Christian theology, Christian hermeneutics, and Christian rhetoric. In each of these stages, the theme of love and the use of signs, together with the utility of adopting secular learnings for Christian purpose, recurs.

　　The article begins with the discussion that the task of Christian theology is to speak of the ineffable God through human words, made possible by the Incarnation of the Word. The semiotic principle to be introduced here is that the realities signified by signs must have been antecedently known by the interpreter. Having adopted teleological conceptions then common in ethics to support his principle of the ordering of love, Augustine demonstrates that God must be known, through love in worship, before one can comprehend the signs of the Bible. The article then turns to Christian hermeneutics. Centered on the interpretation of the ecclesiastically established set of signs that is known as the Bible, the key semiotic observation lies in the inherent ambiguity of words. Due to fluidities in the meaning of signs and the propensity of language to be elevated in religious contexts, understanding biblical signs requires the application of not only literal but also figurative interpretation, governed by the dominical commandment of the love of God and the neighbor. This semiotic analysis of doctr. chr. is completed by investigating briefly the subject of Christian rhetoric. Semiotics is related to rhetoric, in that efficacious communication depends on the listeners’ ability to comprehend the signs, their patience to remain listening, as well as their willingness to act upon what have been heard. Aided by the learning of ancient rhetoric, Augustine maintains the need of eloquence to be in the service of wisdom for Christian preaching to testify to the truth and to respond to the commandment of love. This is done by the appropriate use of rhetoric techniques to influence the listeners’ affections, so as to facilitate transformations of life.

　　This article argues that proclamation itself presupposes theological reflection, just as theology is the result of correct interpretation and effective preaching of the Bible. It concludes by proposing the advantages of bringing to the fore the distinction between signs and signified realities. Focusing on signified realities presupposes the listeners’ prior knowledge of God before they can comprehend the biblical words, while attention to verbal signs deepens our understanding of the characteristics of the verbal medium. The final analysis suggests that given Augustine’s insistence of prior knowledge of God has been matched by recent works of theology while contemporary theological investigations of the verbal medium in terms of semiotics appear to remain, by and large, in short supply, it testifies to the continued relevance of patristic theology and the great promises of semiotic investigations in contemporary theological tasks.
