The Feast of the Transfiguration of Our Lord appears in the Christian Calendar at a strange time. In fact, my understanding is that it was fairly arbitrarily placed on 6th August some centuries ago. The more reasonable date is in the Springtime, as the Church is following the path of Jesus from Galilee to the Cross, and it seems to have found a second home on the Sunday before Lent each year. A sensible place to put it, when considered from the perspective of what the Transfiguration meant to Jesus himself in the context of his coming Passion.
Nevertheless, the Summertime celebration of this important event in our Lord’s life - and in that of his most intimate band of disciples - is a reminder of its broader significance in demonstrating the breaking through of the heavenly, and the fact that faith can take us to places that we neither expect nor necessarily understand.
As the lazy days of Summer give most of us some extra time to think and pray and ponder, as we relax and enjoy holiday and rest, the spiritual intensity of the Transfiguration account is a reminder that there is colour and contrast in what is life-giving and refreshing. Our Lord may have been transfigured as his appearance changed and he became white, but the experience brought depth and meaning, and in that sense produced what I might describe as a spiritual rainbow in the hearts of those who looked on. So, rain or shine today, there is joy in the hearts of Christians in celebrating this festival.
