A commentary on the Johannine Epistles, emphasising their performative, liturgical function and the particular ethical form of worship that they preach. 1-3 John' treats the three letters of John as a unified epistolary package. Taking a thorough and scholarly approach, John Paul Heil proposes two important contributions to the study of 1-3 John. First, he presents new comprehensive chiastic structures for each of the three letters of John based on concrete linguistic evidence in the text. These chiastic structures serve as the guide to a better understanding of for whom John's epistles were meant, and why they were written. Secondly, it treats these letters from the point of view of their worship context and themes. Not only were 1-3 John intended to be performed orally as part of liturgical worship, but together these three letters plead with their audience to engage in a distinctive kind of ethical worship. The three letters of John are most concerned with giving their audience the experience of living eternally by the worship that consists of loving God and one another.
