The purpose of this paper is to enliven the understanding of doctrine in preaching. It is intended for clergy who preach regularly in denominations that have no strict requirements of doctrine. Written from within the United Church of Canada, it carries much reference to that doctrine and polity. Engaging the homiletical theory of faith seeking understanding, it warns of the danger of default doctrine and establishes a discipline to ensure that regular homiletical preparation involves more than simple grace and engages hard questions. The pleasures and depth of theology are rich, and merit reflection not only for the pastoral and intellectual lives of our parishioners but for the fullness of our practice.
