Gregory Palamas

Divine Energies and the Defense of Hesychast Prayer

Life and Context

Early Life and Conversion (1296–1316)

Gregory was born in Constantinople to an aristocratic family with connections to the imperial court. His father, a senator, died when Gregory was young, and Emperor Andronicus II became his guardian. Despite excellent secular education and a promising career in philosophy and government, Gregory felt drawn to the monastic life from an early age.

Around 1316, when he was about twenty, Gregory convinced his mother, two brothers, and two sisters to embrace monasticism. The entire family entered religious life—a remarkable testimony to his spiritual influence. Gregory himself went to Mount Athos, the center of Orthodox monasticism.

Athonite Formation (1316–1331)

On the Holy Mountain, Gregory immersed himself in the hesychast tradition. He studied under experienced elders, practiced the Jesus Prayer with its psychosomatic techniques, and experienced the fruits of deep contemplative practice—including, according to tradition, visions of the uncreated light.

His fifteen years on Athos grounded him thoroughly in both the experiential reality of hesychast prayer and the patristic tradition that supported it. When controversy erupted later, he could speak as both a practitioner and a scholar, combining personal experience with theological precision.

The Hesychast Controversy (1337–1351)

The crisis began with Barlaam of Calabria, a Greek-speaking monk from southern Italy who had absorbed Western scholastic methods. Barlaam attacked the hesychasts on two fronts: he mocked their physical techniques (such as bowing the head toward the heart and regulating breath) as absurd, and he argued that any claim to see divine light was either delusion or merely metaphorical.

Barlaam's critique struck at the heart of Orthodox spirituality. If the light experienced by the hesychasts was not truly God, then the entire tradition of theosis—transformation through genuine encounter with the divine—was illusory. Gregory emerged as the chief defender of hesychasm.

The controversy produced Gregory's major work, the Triads in Defense of the Holy Hesychasts, and culminated in three Church councils that vindicated his position. The councils of Constantinople in 1341 and 1351 affirmed the distinction between essence and energies as Orthodox dogma, and Barlaam was condemned. Gregory himself was later imprisoned during a period of political upheaval but ultimately became Archbishop of Thessaloniki in 1347.

The Essence-Energies Distinction

Gregory's most significant theological contribution addresses a profound dilemma: How can humans have real union with God without dissolving divine transcendence or reducing God to a knowable object?

The Problem

Christian tradition affirms two seemingly contradictory truths:

• Divine transcendence: God in His essence is utterly beyond human comprehension—"dwelling in unapproachable light" (1 Timothy 6:16)
• Real union: Humans can genuinely encounter God and be transformed—becoming "partakers of the divine nature" (2 Peter 1:4)

Barlaam argued that any experience of God must be either symbolic (not really God) or would require comprehending the divine essence (impossible). Therefore, hesychast claims to see uncreated light were either delusion or idolatry.

Gregory's Solution

Gregory drew on the patristic tradition—especially Basil the Great, Gregory of Nyssa, and Maximus the Confessor—to articulate a real distinction within God between essence and energies:

Crucially, the energies are not something less than God or separate from God. They are God Himself in His outward manifestation. When the hesychasts see the uncreated light, they genuinely see God—not God's essence (which remains inaccessible) but God in His self-giving, transforming presence.

"The divine and deifying illumination and grace is not the essence but the energy of God."

Biblical and Patristic Foundations

Gregory demonstrated that this distinction was not a novelty but an articulation of what Scripture and the Fathers had always taught:

• Moses on Sinai: He saw God's "back" (glory, energies) but not His "face" (essence)
• Transfiguration: The disciples saw the uncreated light of Christ's divinity—not a created phenomenon but genuine divine radiance
• Pentecost: The tongues of fire were the Holy Spirit's deifying energy, not merely symbols
• Basil the Great: "We know God from His energies, but we do not claim to approach His essence"
• Maximus the Confessor: Extensive teaching on participation in divine energies through theosis

Theosis and the Uncreated Light

For Gregory, the essence-energies distinction is not abstract philosophy but the theological foundation for theosis—the transformation of human beings through participation in divine life. This is the goal of the entire Christian life and the purpose of hesychast practice.

The Taboric Light

Central to Gregory's teaching is the light of the Transfiguration on Mount Tabor. When Christ was transfigured before Peter, James, and John, He did not acquire something new—rather, He revealed the glory that was always His. This light was not created, not symbolic, not merely moral or intellectual illumination. It was the uncreated divine energy, the same light that the hesychasts experience in deep prayer.

The disciples' eyes were transformed to see what had always been there. Similarly, hesychast practice purifies the nous (spiritual intellect) to perceive the divine light that pervades all creation but remains hidden to unpurified perception.

"The light of the Transfiguration is neither sensory nor intellectual, but spiritual—beyond both sense and mind, visible to those whose eyes of the soul have been purified."

The Human Body in Theosis

Against Barlaam's mockery of physical prayer techniques, Gregory offered a robust theology of the body. Because Christ assumed human nature in the Incarnation—including a body—the body is capable of participating in divine life. The physical techniques of hesychasm (posture, breathing, directing attention to the heart) are not magical rituals but appropriate uses of the body in prayer.

Gregory argued that just as the body will be glorified in the resurrection, so even now it can participate in theosis. The light experienced by hesychasts is not merely spiritual but can overflow into bodily experience—as happened to Moses (whose face shone), Stephen (whose face appeared angelic), and many saints throughout history.

Defense of Hesychast Practice

Gregory defended the specific practices of hesychasm that Barlaam had ridiculed:

Reception and Significance

In Eastern Orthodoxy

The councils of 1341 and 1351 canonized Gregory's teaching as Orthodox dogma. The essence-energies distinction became the theological foundation for understanding theosis, sacramental grace, the spiritual life, and indeed the entire relationship between God and creation. Gregory was canonized in 1368, and the second Sunday of Lent is celebrated as the Feast of St. Gregory Palamas.

His influence on subsequent Orthodox spirituality is immense. The Philokalia contains his writings, and the hesychast tradition he defended continues to flourish on Mount Athos and throughout the Orthodox world.

Ecumenical Dialogue

Relations with Western Christianity have been more complex. Some Western theologians viewed the essence-energies distinction as a novelty or as introducing division into the divine simplicity. However, modern scholarship has found significant parallels in Western mystical theology (Meister Eckhart, Thomas Aquinas's distinction between God's essence and His operations ad extra).

Contemporary ecumenical dialogue often finds Palamite theology a resource for understanding mystical experience and the possibility of authentic encounter with God. Catholic theologians like Hans Urs von Balthasar have engaged sympathetically with Gregory's thought.

Reading Gregory Palamas Today

Gregory's writings can be challenging—polemical in context, philosophically sophisticated, and addressed to controversies long past. Yet his core insights remain vital:

• God is truly accessible: We can genuinely encounter God, not just ideas about God
• Experience matters: Theology must honor the actual experience of the saints, not merely abstract speculation
• The body is included: Salvation encompasses the whole person, body and soul
• Theosis is real: We are called not merely to moral improvement but to transformation by divine grace
• Tradition guides experience: Mystical experience must be tested by apostolic tradition and ecclesiastical discernment
