Melvyn Bragg and guests discuss the form of Christianity adopted by Ostrogoths in the 4th century AD, which they learned from Roman missionaries and from their own contact with the imperial court at Constantinople. This form spread to the Vandals and the Visigoths, who took it into Roman Spain and North Africa, and the Ostrogoths brought it deeper into Italy after the fall of the western Roman empire. Meanwhile, with the Roman empire in the east now firmly committed to the Nicene Creed not the Arian, the Goths and Vandals faced conflict or conversion, as Arianism moved from an orthodox view to being a heresy that would keep followers from heaven and delay the Second Coming for all.

Melvyn Bragg and guests discuss the idea and experience of Christian pilgrimage in Europe from the 12th to the 15th centuries, which figured so strongly in the imagination of the age. For those able and willing to travel, there were countless destinations from Jerusalem, Rome and Santiago de Compostela to the smaller local shrines associated with miracles and relics of the saints. Meanwhile, for those unable or not allowed to travel there were journeys of the mind, inspired by guidebooks that would tell the faithful how many steps they could take around their homes to replicate the walk to the main destinations in Rome and the Holy Land, passing paintings of the places on their route. The image above is of a badge of St Thomas of Canterbury, worn by pilgrims who had journeyed to his shrine.

Melvyn Bragg and guests discuss the Northumbrian man who, for 500 years, was the pre-eminent English saint, to be matched only by Thomas Becket after his martyrdom in 1170. Now at Durham, Cuthbert was buried first on Lindisfarne in 687AD, where monks shared vivid stories of his sanctifying miracles, his healing, and his power over nature, and his final tomb became a major site of pilgrimage. In his lifetime he was both hermit and kingmaker, bishop and travelling priest, and the many accounts we have of him, including two by Bede, tell us much of the values of those who venerated him so soon after his death. The image above is from a stained glass window in the south aisle of the nave in Durham Cathedral: 'St Cuthbert praying before his cell in the Farne Island' With Jane Hawkes Professor of Medieval Art History at the University of York Sarah Foot The Regius Professor of Ecclesiastical History at the University of Oxford and Canon of Christ Church Cathedral And John Hines Professor of Archaeology at Cardiff University Producer: Simon Tillotson

Melvyn Bragg and guests discuss John Wesley (1703 - 1791) and the movement he was to lead and inspire. As a student, he was mocked for approaching religion too methodically and this jibe gave a name to the movement: Methodism. Wesley took his ideas out across Britain wherever there was an appetite for Christian revival, preaching in the open, especially the new industrial areas. Others spread Methodism too, such as George Whitefield, and the sheer energy of the movement led to splits within it, but it soon became a major force. With Stephen Plant Dean and Runcie Fellow at Trinity Hall at the University of Cambridge Eryn White Reader in Early Modern History at Aberystwyth University And William Gibson Professor of Ecclesiastical History at Oxford Brookes University and Director of the Oxford Centre for Methodism and Church History Produced by Simon Tillotson and Julia Johnson

Melvyn Bragg and guests discuss the idea that God created the universe and then left it for humans to understand by reason not revelation. Edward Herbert, 1583-1648 (pictured above) held that there were five religious truths: belief in a Supreme Being, the need to worship him, the pursuit of a virtuous life as the best form of worship, repentance, and reward or punishment after death. Others developed these ideas in different ways, yet their opponents in England's established Church collected them under the label of Deists, called Herbert the Father of Deism and attacked them as a movement, and Deist books were burned. Over time, reason and revelation found a new balance in the Church in England, while Voltaire and Thomas Paine explored the ideas further, leading to their re-emergence in the French and American Revolutions.
