Chapters 4-7 discuss important aspects of 1 John. Chapter 4 argues that its structure or organization is based on rhetorical and conceptual links among the writing's small units. Chapter 5 reads 1 John as a pastoral "in-house" writing, rather than a polemical attack on opponents. Chapter 6 identifies the genre of I John as not a letter or sermon but an epideictic speech that seeks to strengthen the identity, commitments, and practices of its believing recipients. Chapter 7 outlines theological understandings that underpin the writing's pastoral work.
Chapters 8 and 9 focus on 2 and 3 John as writings that provide two different approaches to itinerant teachers. The narrative fiction in 2 John presents the elder's warning and skepticism about itinerant teachers whereas the author of 3 John, by contrast, advocates reception and welcome for itinerant teachers.
