Book excerpt: Acclaimed evangelical speaker and writer Tony Campolo teams up with spiritual director and teacher Mary Albert Darling to reveal some gems from the liturgical Christian tradition to Protestants who may be ready for a refreshing change. While steeped in their own evangelical tradition, the authors are not afraid to venture back into Christian history and reclaim practices that have long been considered exclusively Catholic--including Centering Prayer, along with works by Ignatius Loyola and Catherine of Siena--as excellent spiritual tools to help evangelicals grow in faith and love for the poor. A vital theme in Campolo and Darling's work is that spirituality is not solely an individualistic practice but must lead Christians to love and help the oppressed. True Christian mysticism, they posit, is not an either/or proposition. That's because the nexus between evangelism and justice is to be found in Christian mysticism.
