At first, the readings of the text for the Transfiguration seem a strange choice for a Sunday in Epiphany. Yet Epiphany means the manifestation or the showing of God. The verb for the Transfiguration is like our, word metamorphose - to be changed. It is like the caterpillar that is changed into a beautiful monarch butterfly. It is like the Hans Christian Andersen story where the ugly duckling, grown up, is revealed as a beautiful swan.
Transfiguration is an upside down turning, somersault flipping, darkness into Light experience.
And the Light of Christ, the Light of the Epiphany star that the wise ones followed, can indeed change and transform our very ordinary lives into the Glory of God. In our Old Testament reading with Moses upon the mountain of God, this manifestation of God in the Shekinah of God's Glory is seen as thunder rumbling, smoke erupting, cataclysmic, foundation shaking, all encompassing flaming power. It was a heart stopping, knee trembling, breath grasping experience. To see God is to die. And in the end of this revelation, they saw only Jesus.
