Red-Letter Day
August 6
also known as The Transfiguration, Feast of Tabor
The Transfiguration celebrates the moment when Jesus, on a high mountain with Peter, James, and John, was revealed in divine glory — his face shining like the sun, his clothes dazzling white — while Moses and Elijah appeared with him and the Father's voice declared: 'This is my beloved Son; listen to him.' The feast proclaims the mystery of Christ's two natures: the divine glory that his human flesh ordinarily veiled was momentarily made visible, confirming the disciples' faith before the approaching Passion.
The identification of the Transfiguration mountain with Mount Tabor in Galilee is traditional rather than scriptural — the Gospels do not name the mountain. Tabor was the established identification by the fourth century, though Hermon has also been proposed on geographical grounds. The Eastern theological tradition, especially through Palamas, sees the Transfiguration as revealing the potential of human nature transfigured by divine grace — a vision of theosis (2 Peter 1:4, 'partakers of the divine nature'). The uncreated light seen by the apostles is the same light accessible to purified souls in contemplative prayer. This is the theological backbone of Hesychasm.
The Transfiguration is recorded in all three Synoptic Gospels (Matthew 17:1-8, Mark 9:2-8, Luke 9:28-36) and confirmed by apostolic testimony in 2 Peter 1:16-18. The event is placed immediately after Peter's confession at Caesarea Philippi and Jesus' first Passion prediction, creating a deliberate narrative arc: recognition of Jesus as Messiah, prediction of suffering, and revelation of glory.
The feast's liturgical history is marked by a significant East-West gap. In the East, the Transfiguration was celebrated from at least the ninth century, possibly earlier — its origins may be connected to the dedication of basilicas on Mount Tabor. There is evidence it was originally a pre-Easter (Lenten) observance, fitting the narrative context of the approaching Passion. In the West, the feast was observed locally but was not made universal until Pope Callixtus III extended it to the entire Western church in 1457, commemorating the Christian victory at the siege of Belgrade (1456). News of the victory reached Rome on August 6, and the pope elevated the feast in thanksgiving. (Callixtus III himself died on August 6, 1458.)
The Transfiguration holds unique theological significance in Eastern Orthodoxy through Gregory Palamas (14th century), who taught that the light of Tabor was the uncreated divine energies — God's own light, not a created glow. This became the theological foundation of Hesychasm, the tradition of contemplative prayer seeking direct experience of divine radiance. The Hesychast controversy (1341-1351) was resolved in Palamas's favor, and his teaching became Orthodox dogma.

O God, who on the holy mount revealed to chosen witnesses your well-beloved Son, wonderfully transfigured, in raiment white and glistening: Mercifully grant that we, being delivered from the disquietude of this world, may by faith behold the King in his beauty; who with you and the Holy Spirit lives and reigns, one God, for ever and ever. Amen.
