Hearts on Fire compiles 117 prayers, written by some 40 Jesuits from the time of the foundation of the Society through today. Some are paraphrases of material in the Spiritual Exercises; others are practical applications that grew out of retreat meditations. The prayers are organized within four “weeks” of the Exercises, but each group of selections is eclectic and diverse. The prayer of a Jesuit steeped in the piety of the 17th century may appear next to that of a modern social reformer, for example; a theologian’s reflections may follow thoughts of a parish priest. This product is also available in Spanish.
