Dcn. Seraphim begins The Great Rood Screen Podcast with the legend of Joseph of Arimathea's arrival at Glastonbury, the miraculous Holy Thorn, and the founding of the first Christian church in Britain. He then discusses the podcast's mission and its name, drawn from Tolkien's vision of medieval literature as a "great rood screen" revealing the Holy of Holies. Finally, Dcn. Seraphim concludes with the story of Saint Alban, Protomartyr of Britain, and the earliest historical evidence for Christianity in the British Isles.
