This special issue focuses on art’s role in liturgy and worship. In his elegant book Testimony, Thomas G. Long speaks of public worship as a “soundtrack for the rest of life,” in which “the words and music and actions of worship inside the sanctuary play in the background as we live our lives outside, in the world.” In this issue’s symposium, leading Christian writers and artists address questions provoked by Long’s metaphor: How can we, the church, discover a soundtrack with the maturity and richness we need to sustain us through times of joy and sorrow? And what role does liturgical art—the sounds, objects, motions, and matter we use to worship—have to play as we seek that richness and maturity?
