On Prayer

The spiritual traditions of Cassian had an immeasurable effect on Western Europe. Many different western spiritualities, from that of Saint Benedict to that of Saint Ignatius of Loyola, owe their basic ideas to Cassian. In particular, the Institutes had a direct influence on organization of monasteries described in the Rule of St. Benedict; Benedict also recommended that ordered selections of the Conferences be read to monks under his Rule. Moreover, the monastic institutions Cassian inspired kept learning and culture alive during the Early Middle Ages, and were often the only institutions that cared for the sick and poor. His works are excerpted in the Philokalia (Greek for "love of the beautiful"), the Eastern Orthodox compendium on mystical Christian prayer.
