Using Charles Taylor’s magisterial Sources of the Self: The Making of the Modern Identity as a springboard, this interdisciplinary book explores lived Christian identity through the ages. Beginning with Old Testament figures and moving through the New Testament, the early church, the Middle Ages, and onward, the forty-two biographical chapters—from an outstanding ensemble of contributors—illustrate how believers historically have defined their selfhood based on their relation to God/Jesus. Among the many historical subjects are Justin Martyr, Augustine, Aquinas, Julian of Norwich, Dante, John Calvin, Teresa of Ávila, John Bunyan, Christina Rossetti, Blaise Pascal, Søren Kierkegaard, C. S. Lewis, and Flannery O’Connor—all of whom boldly lived out their Christian identities in their varied cultural contexts. In showing how Christian identity has evolved over time, Sources of the Christian Self offers deep insight into our own Christian selves today.
