The Stages of Spiritual Progress

Updated: Mar 18

Since February 23, Fr Maximos Constas, Director of the Pappas Patristic Institute, has been leading a seminar entitled Solomon's Trilogy: The Stages of Spiritual Progress at the Abigail Adams Institute in Cambridge, MA, exploring the tradition of the threefold ascent to God through purification, illumination, and mystical union.

Solomon's Trilogy: The Three Stages of Spiritual Progress

Christian thinkers from antiquity through the medieval period and beyond have traditionally understood the Christian life as an ascent to God through three stages: (1) purification, (2) illumination, and (3) union with God. These stages were often seen to correspond to the three Solomonic books of the Old Testament: Proverbs, Ecclesiastes, and Song of Songs.

Solomon's Trilogy explores the patristic understandin of spiritual progress and the different stages of the spiritual life by looking at the role of asceticism, allegory, the nature of knowledge, the structure of the world, mystical union with God, and other themes in the writings of Origen, Evagrios, St Gregory of Nyssa, and St Maximos the Confessor
