This Festschrift uses as its starting point the research interests of Christopher Rowland. The collection of essays come from former doctoral students and other friends, all of which shed light on the angelic contribution to the thought-world of developing Christianity. The impact of the Jewish contribution to developing Christian ideology is also assessed, enabling the extent of the impact of the original Jewish sources on contemporary Christian belief to be measured. The distinguished contributors to this volume include Paul Foster, Robin Griffith-Jones, Philip R. Davies, and Crispin Fletcher-Louis.
