"One of the cornerstone messages of the Gospel is the preaching of joy. Having met the myrrh-bearing women after the resurrection, the Lord says to them: Rejoice! And now, on the path toward His suffering on the Cross, He gives His disciples a foretaste of the future of the time of the resurrection."
Troparion, tone 7: Thou wast transfigured on the mountain, O Christ our God, showing to Thy disciples Thy glory as each one could endure; shine forth Thou on us, who are sinners all, Thy light ever-unending. Through the prayers of the Theotokos. O Light-giver, glory to Thee.
