Fr Matthew Roche-Saunders, a Catholic priest from the parish of Aberystwyth is in Rome, following in the footsteps of faithful pilgrims across the centuries. 900 years ago this year, as recorded by the English historian William of Malmesbury, Pope Callixtus II granted a privilege to St Davids to be of significant spiritual importance for pilgrims. As part of our 'In The Footsteps of David' series of programmes celebrating our patron saint, Fr Matthew explores the act of pilgrimage, hearing from others visiting places around the globe linked to Saint David, to understand more about this journey of faith.
