All Christian spirituality is rooted in one central fact: that God became man in Jesus of Nazareth, dwelt among us, suffered, died, and rose again, and remains with the Church according to his promise (Matthew 28:20). It is the encounter with Christ, through the Holy Spirit, uniting the believer with the Father, that defines Christian, Trinitarian spirituality as distinct among world religions. In this class, we will be examining in particular those approaches to and understandings of this encounter which have emerged from the traditions of the Christian East, concentrating upon those texts and authors who have been most formative for the world of Eastern Christianity today.
