Most of these thirty-one essays by Richard Bauckham, a well-known New Testament scholar, were first published between 1979 and 2015 in journals and multi-authored volumes. Two are previously unpublished and one has not been published in English before. They range widely over early Christianity and early Christian literature in both the New Testament period and the early patristic period, reflecting the author's conviction that the historical study of early Christianity should not isolate the New Testament literature from other early Christian sources, such as the apostolic fathers and the Christian apocryphal literature. Some of the essays develop further the themes of the author's books on aspects of the Gospels, such as the intended audiences of the Gospels, the way in which Gospel traditions were transmitted, the role of the eyewitnesses in the origins of the Gospels, the importance of Papias's evidence about Gospel traditions, and the relationship between canonical and Gnostic Gospels. Some of the essays relate to important persons, such as Peter, Barnabas, Paul and James. These include a full investigation of the evidence for the martyrdom of Peter and an attempt to locate the estate of Publius where Paul stayed on Malta. There are studies of the Sabbath and the Lord's Day in both the New Testament and patristic periods. There are studies that survey most of the main categories of apocryphal Christian literature, including apocryphal Gospels and Acts, and with a special focus on the non-canonical apocalypses, such as the Apocalypse of Peter and the Latin Vision of Ezra.
