Everyday worship practices—from praying the rosary to moments of recognizing the beauty of God's creation, from being moved by the power of music to praying Vespers on an iPad—not only take place at different locations and during different days of the week but also dynamically interact with one another. The Liturgy of Life examines the interrelationship between the practice of Sunday Eucharist and the many nonofficial worship practices that mark the everyday lives of Christians who continually negotiate the boundaries of official teaching on liturgy. Drawing on the writings of theologians and sociologists of lived religion and data from an ethnographic research project, this timely work stretches the contextual horizon of liturgical scholarship and presents a provocative and dynamic paradigm of Christian worship for the twenty-first century.
