This commentary on the second epistle of Peter offers a fresh examination of a key New Testament text. Relying on newly available research, A. Chadwick Thornhill brings a multi-pronged approach to his study through his use of a range of methods including narrative theology, and historical, social, cultural, literary, rhetorical, discourse, and linguistic analysis. Thornhill challenges existing paradigms pertaining to the composition of 2 Peter, asks new questions regarding authorship and genre, and revisits the identification of the text as a pseudonymous testament, as it has most recently been understood. His study enables new insights into the letter's message as it would have been understood in its ancient context. Written in an accessible style, Thornhill's commentary concludes by offering reflections on 2 Peter's contributions to the theology of the New Testament and its relevance for the late modern world.
