This study explores the practice of hospitality within the Pauline churches and links this practice with mission. It is theoretically informed by Käsemann’s (1963) emphasis on the unity of the church as “an eschatological datum.” While highlighting faith, Käsemann downplays the role of organization and religious practices. Neither he nor missiological studies deal with the practice of hospitality within this context. Hospitality has been interpreted in the literature primarily as an ethic one should adopt towards strangers. Alternatively, this study interprets it as a ritual-like practice aimed at family, friends and strangers in the context of meal gatherings. The question is whether it served as an instrument of koinonia, a practice aimed to create, maintain and extend the Pauline churches as an open network, without denying the role of kerygma. This enquiry utilizes two methodological approaches to answer this question. First of all, it uses Stark’s (1996) network theory of conversion, in order to provide a framework for hospitality in early Christian mission. Secondly, it uses Bell’s (1992) ritual theory in order to interpret meal fellowship in the Pauline churches. Presupposing that science is a conversation, the relationship between missiology and anthropology is depicted as a conversation, ideally an ongoing conversation. This conversation is possible and potentially coherent because the “basic convictions” of both disciplines, respectively love and power, do not contradict each other. The key contribution of this study is that it shows that several practices in the Pauline churches such as welcoming, foot washing, seating order, distribution of portions, etc. qualify as ritual-like. This finding establishes the ritual-like character of meal fellowship within the Pauline churches. Yet, these practices were found ambiguous. They were not simply an instrument to achieve social integration or the transmission of beliefs. While they set the meal off from daily reality, they did not resolve the tension within the churches. Paul knew that this tension was part of a larger apocalyptic picture, the battle between Christ and Satan. Through ritual-like practice he participated in this battle, employing a “poetics of power” that fostered the church as an open network. / Christian Spirituality, Church History and Missiology / D.
