“According to the teaching of many Church Fathers, particularly those of the East, Christian life consists not so much in being good as in becoming God.” So begins Michael Casey in this bold and important book which explores the lost doctrine of deification or divinization while reflecting on the Gospel of Mark. If his works strike you as scandalous, hold them alongside this gem of a quotation from the twelfth century Cistercian mystic and theologian, William of St Thierry: “When the soul reaches out in love to anything, a certain change takes place in it by which it is transmuted into the object loved.” (Meditations 3.8). Deification is not about assuming the nature of God, but through love we are invited into a type of mystical conformity with Christ. And by exploring this theme in a book about the Gospel of Mark, Casey illustrates how it has been a part of Christian identity from the very beginning.
