NOTES for Mat 17:1-13
The most important encounters between God and humanity took place on a mountain peak: Moses received the law, and Elijah heard the breath of the Spirit. Now Jesus ascends the mountain in order to begin, in Himself, the transfiguration of humanity: from the sickness of fear and hatred to divine light.
Below, on level ground, disappointment and rejection always awaited the prophets: Moses saw the golden idol, and Elijah saw apostasy and persecution. Jesus comes down in order to go to meet His suffering, death, and resurrection, so that the transfiguration of the beloved Son would not stop with Him, so that everyone could follow His path, become a beloved son or daughter of the Father, and live by His light. On this day we can enter into this bond between God's light and Christ's cross, which opens the way to the universal Resurrection.
