St. Gregory of Nyssa (335-394 CE), who came from an illustrious Christian family of Capadocia, became bishop of the small town of Nyssa in 371 and is known as one of the founders of mystical theology in the Church. In
The Life of Moses
, one of the most important books in the study of Christian mysticism, Gregory retells the story of Moses's life from the biblical account in Exodus and Numbers and then refers back to these stories as the basis for profound spiritual lessons. The ultimate goal of Gregory's spirituality is to strive for infinite progress in the never-completed journey to God. His exhortations to lead a life of virtue will inspire all who hope to increase their knowledge and love of God.
