This book studies comparisons and possible trajectories between three 'catholic' epistles, and traditions associated with Jesus. Part A analyzes why James would recall the teachings of Jesus, how he alters these teachings, and what such adaptation suggests about his audience. Part B turns to the Jesus tradition and 1 and 2 Peter. What can 1 Peter's use of Isaiah 53 tell us about the historical Jesus? How has 1 Peter conflated early Jesus traditions with those of ancient Judaism in order to develop certain ideas? How does 2 Peter allude to Gospel traditions? Moreover, how does the author of 2 Peter use early Jesus traditions as a sort of testimony? The book is an important contribution to scholarship on source criticism, ancient rhetoric, and the influence of Hellenistic, Judean and Roman traditions on early Christianity.
