On Loving God

Bernard of Clairvaux wrote this treatise on the love of God around 1127 at the request of Haimeric, the papal chancellor, who had asked for guidance on why and how God should be loved. Writing during the height of his influence as abbot of Clairvaux and advisor to popes and kings, Bernard addresses fundamental questions about divine love that were central to twelfth-century monastic spirituality and the broader Christian life.

Bernard argues that love of God progresses through four ascending degrees: loving oneself for one's own sake, loving God for one's own benefit, loving God for God's sake, and finally loving oneself for God's sake alone. He demonstrates that while the initial motivation for loving God may be self-interest or fear, authentic spiritual growth transforms this into pure love that seeks nothing beyond God himself. The treatise carefully distinguishes between different types of love—natural affection, rational choice, and spiritual devotion—while insisting that even imperfect love can serve as a pathway to perfect love. Bernard grounds his analysis in close reading of Scripture, particularly the Song of Songs, and draws on his deep pastoral experience to show how contemplative union with God emerges from disciplined spiritual practice.

De diligendo Deo became one of the most influential works of medieval mystical theology, shaping centuries of Christian reflection on the nature of divine love and spiritual progress. Its psychological insight into the transformation of human motivation and its practical wisdom about spiritual development have made it a cornerstone of monastic formation and contemplative spirituality. The work's integration of rigorous theological analysis with experiential knowledge of prayer and contemplation established Bernard's reputation as both doctor of the church and mystical theologian. Who should read this: those seeking to understand the classical Christian teaching on love of God, students of medieval mystical theology, and anyone interested in how spiritual desire can be purified and directed toward union with God. This is not light devotional reading but requires engagement with Bernard's dense theological vocabulary and medieval mindset.
