This feast day has been celebrated in the Eastern Churches since the latter part of the fourth century and in the West since the 9th century.
While praying with Peter, James and John on a mountain, the Lord Jesus was transfigured, showing forth His divine glory and majesty.
A cloud descended and out of the cloud came a voice saying, “This is my beloved Son: hear him” (St. Luke 9:34) This occurred towards the end of our Lord’s ministry, and soon before His crucifixion.
Although by the world’s standards our Lord’s earthly ministry would seem to be a complete failure – as He was crucified, dead and buried – God the Father revealed to these three witnesses that Jesus’ complete gift of selfless love would bring victory and triumph in the end.
May we all be delivered from the disquietude of this world and be permitted to behold the King in all His transfigured glory and beauty. (The day’s collect, page E 98, The People’s Anglican Missal)
