In celebrating the feast of the Transfiguration of the Lord, the Church presents to us the testimony of God the Father who introduces his Son to the world with these words: "This is my beloved Son. Listen to him." These words of the Father are the whole program of the Church and of our Christian lives. In addition, in the Transfiguration, Pope St. Leo the Great tells us that, in witnessing the glory of Christ, the Apostles are fortified for their future experience of seeing him in the humiliation of his Passion and Death. The Transfiguration fortifies us also in our faith in Jesus as the Son of the eternal Father.
