The Light of Tabor

The Transfiguration of Christ on Mount Tabor (Matthew 17:1-9) is, for St. Gregory Palamas, the disclosure of the uncreated divine energy — the same light the hesychasts claim to behold in prayer. Against Barlaam, who called it a created, transient symbol, Palamas argued from Scripture, the Fathers, and the Church’s hymnography that the light was the natural radiance of the Godhead, seen not by the apostles’ ordinary sight but by senses transformed by grace.

Tradition: Pan-Orthodox (Church Father)

The Heart of the Controversy

The dispute that produced the Triads turned on a single luminous event. The hesychasts of Mount Athos claimed to experience, in the depths of prayer, a real vision of divine light. Barlaam of Calabria mocked this claim and, pressing the point to its scriptural test case, argued that even the light of the Transfiguration — the brightness that shone from Christ on Mount Tabor — was a created phenomenon: “a sensible light, visible through the medium of the air, appearing to the amazement of all and then at once disappearing,” called divine only because it served as “a symbol of divinity” (Palamas, Triads III.i.11, reporting Barlaam; trans. Gendle, CWS, p. 58).

For Palamas, this was intolerable. If the Tabor light was merely a created sign that flashed and vanished “in a single hour,” then Christ in glory was reduced to “those creatures one calls ephemeral,” and the apostles’ vision was an illusion of no lasting reality (Triads III.i.11; Gendle, p. 58). The whole question of whether human beings can truly participate in God hung on the answer.

The Light Was Uncreated

Palamas marshals a chain of patristic authorities to establish that the Tabor light is the very light of the Godhead, not a created emblem of it. He appeals to Pseudo-Dionysius the Areopagite, who said the saints will be illumined hereafter “just as it illuminated the disciples at the time of the most divine Transfiguration,” and to St. Gregory the Theologian: “In my view, he will come as he appeared or was manifested to the disciples on the Mountain, the divine triumphing over the corporeal” (Triads III.i.10; Gendle, p. 59, citing Gregory Nazianzen, Homily 40.6 [PG 36:365A]).

The decisive test, for Palamas, is the word unapproachable. Drawing on St. Basil the Great’s confession of “the God who dwells in light unapproachable” (cf. 1 Timothy 6:16), he reasons:

“This is why the apostles fell to the ground, unable to rest their gaze on the glory of the light of the Son, because it was a ‘light unapproachable.’ … If then the unapproachable is true and this light was unapproachable, the light was not a simulacrum of divinity, but truly the light of the true divinity, not only the divinity of the Son, but that of the Father and the Spirit too.” (Triads III.i.12; Gendle, p. 59)

A created symbol could be approached, measured, and grasped; the very fact that Peter, James, and John were cast down confirms that what shone was nothing less than God. Palamas is careful, however, with the word “symbol”: he concedes it may be used of the Tabor light “wisely and properly understood,” but he notes that “the choir of inspired theologians have almost all been chary of calling the grace of this light simply a symbol,” lest the term mislead people into supposing the light “a created reality, alien to the divinity” (Triads III.i.13; Gendle, pp. 59-60).

Palamas presses Barlaam’s logic to absurdity. Gregory the Theologian had written that the divinity will be revealed “as light,” and Chrysostom, with the definite article, spoke of “the divinity” — “the true Godhead” — manifesting its rays. If the light were only a created symbol of another nature, Palamas argues, “one would have to say, not that the divinity manifested was light, but that light caused the divinity to appear” — which is precisely the reverse of what the Fathers say (Triads III.i.12; Gendle, p. 59). A drawing of a man is not humanity, and the picture of an angel is not the nature of an angel; a created symbol cannot be the divinity it depicts. The Tabor light, by contrast, is the Godhead’s own self-showing, the radiance proper to the divine nature itself.

Not a Display but a Disclosure — and Transformed Eyes

Crucial to the Palamite exegesis is that nothing new was added to Christ on the mountain. Citing St. John of Damascus, Palamas insists:

“Christ is transfigured, not by putting on some quality He did not possess previously, nor by changing into something He never was before, but by revealing to His disciples what He truly was, in opening their eyes and in giving sight to those who were blind.” (Triads III.i.15; Gendle, p. 61, quoting John Damascene)

The change, therefore, was not in Christ but in the apostles. The Transfiguration was not a created light-show projected for ordinary eyes; it was the unveiling of a glory always present, “hidden by the flesh,” now perceived because the disciples’ faculties were elevated to perceive it. Palamas states this with full force:

“Thus He was divine before, but He bestowed at the time of His Transfiguration a divine power upon the eyes of the apostles and enabled them to look up and see for themselves. This light, then, was not a hallucination but will remain for eternity, and has existed from the beginning.” (Triads III.i.15; Gendle, pp. 61-62)

He borrows Basil’s image of “his divine power” appearing “as it were as a light through a screen of glass, that is to say, through the flesh of the Lord,” illuminating “those who have purified the eyes of the heart” (Triads III.i.15; Gendle, p. 61). The vision is supernatural — “visible in this life only to those whose eyes have been transformed by grace” (Gendle’s note to Triads III.i, n. 19, p. 138). The apostles saw, in Andrew of Crete’s paradox, by “the faculty of truly seeing by virtue of seeing nothing,” having “transcended every sensible and intellectual perception” (Triads III.i.22; Gendle, p. 64).

This is the precise pivot of Palamas’s argument, and it distinguishes his position from two errors at once. Against Barlaam, the light is not a created phenomenon registered by ordinary eyesight — for ordinary eyesight perceives only created things, and the apostles were cast to the ground precisely because what they saw exceeded the created order. But neither was the vision a purely mental act, an idea formed by the intellect: Palamas notes that “the untransformed mind cannot” attain such a vision (cf. Gendle’s note on Stephen’s vision, Triads III, n. 88, p. 158). The Transfiguration was a real seeing of a real light, but by a faculty raised above its natural power. The senses themselves are deified; “the whole man, body as well as soul, must be transformed” (Gendle’s note, p. 156). This is why Palamas can affirm that the light was both objective — eternally Christ’s own glory — and perceptible only to the purified: the light does not change, but the seer must be changed to bear it. The Transfiguration is thus the model of all genuine vision of God, in which God gives not only Himself to be seen but the very power to see Him.

The Hesychasts See the Same Light

This is the hinge on which Palamas’s whole defense of the monks turns. The light the hesychast beholds in pure prayer is not a different light, lower or imaginary, but the identical uncreated radiance of Tabor. Citing Symeon Metaphrastes’ redaction of Macarius the Great, Palamas teaches that the glory that “shone on Moses’ face” and blazed on the mountain is “received now in part” by “the faithful souls of the saints … even now in the inner man,” who are thereby “transfigured from glory to glory according to the same image” (Triads III.i.10; Gendle, pp. 58-59, quoting 2 Corinthians 3:18). What the disciples saw on Tabor is the firstfruits and pledge of what the deified will see eternally, and what the saints already taste in this life. To call the Tabor light created was, for Palamas, therefore to deny the reality of deification itself.

The Patristic and Liturgical Witness

Palamas does not argue as an innovator but as a witness gathering the tradition. His Transfiguration dossier draws on Dionysius the Areopagite, Gregory the Theologian, Basil the Great, John Chrysostom, Maximus the Confessor, Macarius/Symeon Metaphrastes, John of Damascus, and Andrew of Crete (Triads III.i.10-20; Gendle, pp. 58-64). For the broader patristic and feast-day setting, see The Great Feasts.

Tellingly, Palamas appeals repeatedly to the Church’s own hymns as the lived dogmatic memory of the faithful. He quotes the Transfiguration hymnography directly:

“This is why we sing together to the Lord when we celebrate the annual Feast of the Transfiguration: ‘In Your light which appeared today on Thabor, we have seen the Father as light and also the Spirit as light,’ for ‘You have unveiled an indistinct ray of Your divinity.’” (Triads III.i.12; Gendle, p. 59, quoting the feast’s hymnody)

And again: “On the holy Mountain, O Christ, You showed the splendour of Your divine and essential beauty, hidden under the flesh, and enlightened, O Benefactor, the disciples who accompanied You” (Triads III.i.20; Gendle, p. 64).

The Theology of the Feast in Orthodox Worship

The Feast of the Transfiguration (August 6 / August 19) carries in its services precisely the theology Palamas defended. The Kontakion sings that Christ was transfigured “as far as they could bear it” (hos echoroun) — the phrase that captures the Palamite point that the limiting factor was the disciples’ capacity, not the light’s reality. The Troparion (Tone 7) prays: “Thou wast transfigured on the mountain, O Christ God, revealing Thy glory to Thy disciples as far as they could bear it. Let Thine everlasting Light also shine upon us sinners, through the prayers of the Theotokos. O Giver of Light, glory to Thee!” (see The Great Feasts). The petition that the “everlasting Light” shine “upon us sinners” is itself a prayer for the hesychast vision — that the same uncreated light disclosed on Tabor would illumine the worshipper.

It is no accident that the Orthodox Church commemorates St. Gregory Palamas on the Second Sunday of Great Lent, immediately after the Sunday of Orthodoxy. His vindication of the uncreated light is treated not as a peripheral mystical opinion but as a second triumph of Orthodoxy, securing the dogmatic ground of theosis (see The Jesus Prayer).
