From the Lost Teaching of Polycarp

"This book adds significantly to our understanding of the life and rhetorical work of Polycarp of Smyrna, one of the most important figures in post-apostolic Christianity. It proposes that two sources of his teaching may be identified and restored to him: the oral teaching preserved by Irenaeus of Lyons in Against Heresies 4.27.1-32.1, and the writing known as the Ad Diognetum."--BOOK JACKET.
