The New Monastic Movement is a vibrant source of renewal for the church’s life and mission. Many involved in this movement have quoted Dietrich Bonhoeffer’s conviction that the church must recover ancient spiritual disciplines if it is to effectively engage the powers that be. Melodies of a New Monasticism adopts a musical metaphor of polyphony (the combination of two or more lines of music) to articulate the way that these early Christian virtues can be woven together in community. Creatively using this imagery, this book draws on the theological vision of Bonhoeffer and the contemporary witness of George MacLeod and the Iona Community to explore the interplay between discipleship, doctrine, and ethics. A recurring theme is the idea of Christ as the cantus firmus (the fixed song) around which people perform the diverse harmonies of God in church and world, including worship, ecumenism, healing, peace, justice, and ecology.
