Transfiguration of our Lord
Commemorated on August 6
The event of the Transfiguration is recorded in three of the four Gospels:Matthew 17:1-9, Mark 9:2-8, and Luke 9:28-36. Jesus took the Apostles Peter, James, and John with Him up upon a mountain, and while they were on the mountain Jesus was transfigured. His face shone like the sun, and His garments became glistening white.
Moses and Elijah appeared with Christ, talking to Him. Peter declared how good it was for them to be there and expressed the desire to build three tents for Moses, Elijah, and Christ. This reference to the tents could imply that this occurred during the time of the Feast of Tabernacles when the Jews would be camping out in the fields for the grape harvest; for this Feast had acquired other associations in the course of its history, including the memory of the wanderings in the wilderness recorded in the Old Testament book of Exodus.
While Peter was speaking, a bright cloud overshadowed them. A voice came from the cloud saying, "This is my beloved Son, with whom I am well pleased; listen to Him." When the disciples heard this they fell on their faces filled with awe. Jesus came to them and told them to not be afraid. When the three looked up they saw only Jesus.
As Jesus and His disciples came down the mountain, He told them not to speak of what they had seen until He had risen from the dead.
Άπολυτίκιον (Ἦχος βαρύς)
Μετεμορφώθης ἐν τῷ ὄρει Χριστὲ ὁ Θεός, δείξας τοῖς Μαθηταῖς σου τὴν δόξαν σου, καθὼς ἠδύναντο. Λάμψον καὶ ἡμῖν τοῖς ἁμαρτωλοῖς, τὸ φῶς σου τὸ ἀΐδιον, πρεσβείαις τῆς Θεοτόκου, φωτοδότα δόξα σοι.
Apolytikion (Grave Tone)
You were transfigured on the Mount, Christ God revealing Your glory to Your disciples, insofar as they could comprehend. Illuminate us sinners also with Your everlasting light, through the intercessions of the Theotokos. Giver of light, glory to You.
Κοντάκιον (Ἦχος βαρύς)
Ἐπὶ τοῦ ὄρους μετεμορφώθης, καὶ ὡς ἐχώρουν οἱ Μαθηταί σου τὴν δόξαν σου, Χριστὲ ὁ Θεὸς ἐθεάσαντο, ἵνα ὅταν σε ἴδωσι σταυρούμενον, τὸ μὲν πάθος νοήσωσιν ἑκούσιον, τῷ δὲ κόσμῳ κηρύξωσιν, ὅτι σὺ ὑπάρχεις ἀληθῶς, τοῦ Πατρὸς τὸ ἀπαύγασμα.
Kontakion (Grave Tone)
You were transfigured upon the mount, O Christ our God, and Your disciples, insofar as they could bear, beheld Your glory. Thus, when they see You crucified, they may understand Your voluntary passion, and proclaim to the world that You are truly the effulgence of the Father.
