As part of our series of programmes making the 900th anniversary of St David's international recognition, presenter and pastor Jonathan Thomas tries out a day in the life of St David. Jonathan's own contemporary religious traditions are quite different from the ancient practices of a Celtic saint. As he visits key locations in West Wales connected with David, and follows in his footsteps and practices (or their present-day equivalents) - what will he make of life lived in the style of a 6th century monk? And what will today's West Walians make of him? In this programme, Jonathan tries cold water immersion, street preaching, contemplative practices and more. Helping him along the way are St Davids' Cathedral librarian Mari James; Archdeacon of Ceredigion and dairy farmer Eileen Davis; and chaplain at the University of Wales Trinity St David, Emma Whittick. No day in the life of a saint is complete without a trusty band of followers: Jonathan is joined for part of the programme by students from Trinity St David's Lampeter Campus, and conducts some of his saintly duties in the contemplative environment of the campus' chapel, refectory and library.
