The literary status of 1 Cor 5–7 is diversely considered in scholarly literature. Sometimes these chapters are seen as a stand-alone part of the letter, sometimes they are divided in separate blocks, chapters 5–6 on the one hand and chapter 7 on the other. However, an original approach that pays close attention to the structure of the text makes it possible to show the neat architecture of this larger textual unit. The concentric structure of the three chapters (A–B–A’) highlights their literary unity and stresses the significance of the central chapter, which correspondingly possesses the greatest theological density of the whole section.
