The Transfiguration is the clearest epiphany recorded in Scripture. Moses and Elijah, representing the Law and the Prophets, appear with Christ, bearing witness to him as Messiah. The light emanating from Christ in this vision has provided a long line of Church fathers with a theme that has become the unifying thread in Byzantine theology — the vision of God as light.
This tradition is founded on St John, one of Christ’s companions on the mountain. He opens his account of the good news by saying, “The Word was the true light that enlightens all people. He lived among us, and we saw his glory!”
In this light, humanity, along with all creation, enjoys this deifying vision. Furthermore, our happiness will increase along with our ability to see the reality of this manifestation.
