This book discusses the teachings of the Doctor of Prayer, Saint Alphonsus Liguori, on prayer, which speaks to today's believing community. Father Dennis Billy presents useful parallels between the spiritual teachings of Saint Alphonsus Liguori and the ministry of spiritual direction. With Open Heart serves as a practical foundation for those practicing spiritual direction. At the end of each chapter, Fr. Billy provides a series of reflection questions to help spiritual directors relate Saint Alphonsus' spiritual doctrine to current practices in spiritual direction.
