From Fr. Boyer’s homily on Sunday on the Transfiguration of Jesus (Mark 9:2-10):
If Peter, James, and John no longer saw a man from Nazareth but the glory of his exaltation, then we no longer see bread on this altar; but what it becomes for us.
If Peter, James and John no longer saw the man they followed up that mountain
but saw the glory of divine life in him, then we no longer see each other just a neighbor or a stranger for by grace that same glory shines in each of us.
If Peter, James, and John heard a voice that said: “Listen to him.” So have we.
If Peter, James, and John can take the risk of following Jesus even when they did not understand where he would lead them and what it would mean, so can we.
