Cardinal Robert Sarah brings his vast experience as priest, bishop and cardinal to bear on the subject of sacred music. In dialogue with musician Peter Carter he speaks on the theological issues relevant to music in the liturgy in today’s church, and addresses the many practical questions faced by pastors and musicians around the world. With discussion of how to approach the challenges of supporting beautiful liturgy with sacred music, the importance of communal singing of the Divine Office, and the relationship of liturgical music to holiness, Cardinal Sarah's vigorous teaching, deeply rooted in the tradition of the Church and papal documents, will encourage all to lift their voices with renewed inspiration and join in the song of the Lamb.
