The Transfiguration of the Lord, recalled by today’s liturgy casts a dazzling light on our daily lives and makes us turn our minds to the immortal destiny which that event in itself overshadows. On the summit of Tabor, Christ unveils for a few moments the splendor of his divinity, and manifests himself to the chosen witnesses as he really is, the Son of God, “the radiance of the Father's glory and the imprint of his substance” (Cf. Hebr. 1:3);…That body, which is transfigured before the astonished eyes of the apostles, is the body of Christ our brother, but it is also our body called to glory; that light that floods it is and will also be our share of inheritance and splendor. We are called to share in so much glory because we are “partakers of the divine nature” (2 Peter. 1:4). An incomparable lot awaits us, if we have done honor to our Christian vocation: if we have lived …the commitments our our baptism imposes on us.
