In his Treatise On the Preparation and Delivery of Sermons, the Southern Baptist preacher and educator of the latter nineteenth century, John A. Broadus, acknowledged the influence of classical and contemporary theorists upon his work. Among those named, particularly with regard to notions of argument, was Richard Whately, the Anglican Archbishop and rhetorical theorist of the early nineteenth century. The research task involved in this thesis was to determine whether and to what extent Whately's theory of argument was employed in Broadus's homiletic theory and practice. The writer gathered his data using methods of documentary research. Most of the sources were available at local libraries. Others, however, were obtained from the Universities of Kansas, Iowa, and Michigan. Materials by and concerning Broadus were obtained from various Baptist historical agencies.
