The Transfiguration narratives have received considerable attention from New Testament scholars, but so far very little has been written about them from the point of view of their reception-history. The purpose of this article is to examine the ways in which they have been interpreted in the Latin West from the time of Hilary of Poitiers in the fourth century to Peter of Blois in the early thirteenth. Among these writers, from the big names like Jerome to the lesser known figures like Peter of Celle, a varied tapestry emerges where light allegory plays an important part, whether in the symbolisms given to the choice of the three disciples, Peter, James and John, or to the dazzling clothes of Christ as baptismal – a particular insight of Bede, which keeps recurring in subsequent writers and preachers. Unlike the East, where the Transfiguration became a major festival on 6 August from the seventh century onwards, the Latin West was slow to absorb it; but it was given particular impetus by Peter the Venerable, Abbot of Cluny, in the twelfth century. Whether read as narrative in connection with Lent (‘glory before cross’), or as a festival in its own right, the Transfiguration emerges as an unusually rich source of biblical interpretation that poses real challenges to the use of the religious imagination today. And it provides a significant contribution to the development of a balanced view of reception-history in our own time.
