Open AccessA practical theological foundation for church growth as communicative act in the service of the gospel. The aim of this article is to reflect on a pracical theological perspective on the theoretical premises of church growth. This is done within the framework of the postmodern paradigm. Church growth focuses on the analysis, description and explanation of the practical situations of congregations in order to enhance church management. The episttmological framework of this aricleis the distinction metatheory, basis theory and theory of practice. The focus is on the relationship between basis theory and the theory of the practice of church growth. The aricle departs from an approach where empirical data form the basis for the construction of a praxis for church growth. The author argues for a biblical foundation by means of which the empirical data should be evaluated in order to devise a model for praxis.
