Few Christians are comfortable uttering the terms “passion” and “spirituality” in the same breath. But Dreyer shows how diverse passion is and how it can be a part of every Christian life -- from cries of love to virtuous action. To illustrate her point, she examines the work of two medieval women mystics – one who writes in a very symbolic, analytic style (Hildegard), and one whose expression competes with the world’s most intense love poetry (Hadewijch).
