There has been a revival of all things Celtic in recent decades, producing everything from Irish folk music to a rise in pagan mysticism. By contrast, Tracy Balzer's book, Thin Places: An Evangelical Journey into Celtic Christianity is written to introduce contemporary Christians to the great spiritual legacy of the early Celts, a legacy that has remained undiscovered or inaccessible for many in the evangelical tradition. Thin Places not only reveals the deeply scriptural, sacramental faith of the Celts, but also provides ways for us to learn from this ancient faith expression, applying fresh and lively spiritual disciplines to our lives today.
