This article defends the salience of situating Christ worship in the context of urban neighbourhoods and identifies some historical problems in conceptualising belonging at that level of society, akin to similar work on other levels of society such as the household and polis. An ekklēsia or collegium is, like all neighbourhood structures, capable of fostering or delimiting social interactions among neighbours who identify differently. A case study of 1 Cor 14.22–5 illustrates how Paul's model ekklēsia functioned in the context of the neighbourhood, and considers the impact of adding the ekklēsia to the street on which it was located.
