In the context of the current debates about an appropriate understanding of the apostle Paul, Florian Wilk offers a generally understandable interpretation of the first letter to the Corinthians. It collects the topic and structure, language use, historical background, intertextual references and theological points of the text. The text proves to be a uniform document of instruction. In it, Paul discusses a variety of problems and questions that arise from the existence of a heterogeneous community of believers in Christ in a multicultural city. He develops answers and solution approaches from a clear program: the addressees should learn to understand themselves as God's assembly and to shape their existence accordingly, congregationally and individually. The orientation towards Christ as the crucified and risen one serves this purpose. It takes place on the basis of biblical standards, in ecumenical consensus, in the ways of the apostle and in the prospect of the consummation of salvation - and thus leads to a life of wisdom, faithfulness and love.
