George A. Maloney, S.J., provides a great service by bringing to the public the first modern English translation of the spiritual homilies and Great Letter of Pseudo- Macarius, a Syrian monk of the fourth century whose identity is still the subject of scholarly investigation. The Fifty Homilies, in the form of a practical, monastic pedagogy, reveal the typical traits of Eastern Christian asceticism, with particular emphasis on the spiritual combat, the action of the Holy Spirit, and the importance of interior prayer. The Great Letter discusses the purging of the passions to bring the Christian into a state of tranquility and integration, and addresses the monastic community with instructions regarding organization, humility, and prayer.
