"And he was transfigured before them ..."
15. And after six days Jesus took with him Peter and James and John his brother, and led them up a high mountain apart. And he was transfigured before them, and his face shone like the sun, and his garments became white as light. And behold, there appeared to them Moses and Elijah, talking with him. And Peter said to Jesus, "Lord, it is well that we are here; if you wish, I will make three booths here, one for you and one for Moses and one for Elijah". He was still speaking, when lo, a bright cloud overshadowed them, and a voice from the cloud said, "This is my beloved Son, with whom I am well pleased; listen to him". When the disciples heard this, they fell on their faces, and were filled with fear. But Jesus came and touched them, saying, "Rise, and have no fear". And when they lifted up their eyes, they saw no one but Jesus only.
And as they were coming down the mountain, Jesus commanded them, "Tell no one the vision, until the Son of man is raised from the dead" (Mt 17:1-9).The event of the Transfiguration marks a decisive moment in the ministry of Jesus. It is a revelatory event which strengthens the faith in the disciples' hearts, prepares them for the tragedy of the Cross and prefigures the glory of the Resurrection. This mystery is constantly relived by the Church, the people on its way to the eschatological encounter with its Lord. Like the three chosen disciples, the Church contemplates the transfigured face of Christ in order to be confirmed in faith and to avoid being dismayed at his disfigured face on the Cross. In both cases, she is the Bride before her Spouse, sharing in his mystery and surrounded by his light.This light shines on all the Church's children. All are equally called to follow Christ, to discover in him the ultimate meaning of their lives, until they are able to say with the Apostle: "For to me to live is Christ" (Phil 1:21). But those who are called to the consecrated life have a special experience of the light which shines forth from the Incarnate Word. For the profession of the evangelical counsels makes them a kind of sign and prophetic statement for the community of the brethren and for the world; consequently they can echo in a particular way the ecstatic words spoken by Peter: "Lord, it is well that we are here" (Mt 17:4). These words bespeak the Christocentric orientation of the whole Christian life. But they also eloquently express the radical nature of the vocation to the consecrated life: how good it is for us to be with you, to devote ourselves to you, to make you the one focus of our lives! Truly those who have been given the grace of this special communion of love with Christ feel as it were caught up in his splendour: he is "the fairest of the sons of men" (Ps 45:2), the One beyond compare.
"This is my beloved Son": listen to him!
16. The three disciples caught up in ecstasy hear the Father's call to listen to Christ, to place all their trust in him, to make him the centre of their lives. The words from on high give new depth to the invitation by which Jesus himself, at the beginning of his public life, called them to follow him, to leave their ordinary lives behind and to enter into a close relationship to him. It is precisely this special grace of intimacy which, in the consecrated life, makes possible and even demands the total gift of self in the profession of the evangelical counsels. The counsels, more than a simple renunciation, are a specific acceptance of the mystery of Christ, lived within the Church.
In the unity of the Christian life, the various vocations are like so many rays of the one light of Christ, whose radiance "brightens the countenance of the Church." The laity, by virtue of the secular character of their vocation, reflect the mystery of the Incarnate Word particularly insofar as he is the Alpha and the Omega of the world, the foundation and measure of the value of all created things. Sacred ministers, for their part, are living images of Christ the Head and Shepherd who guides his people during this time of "already and not yet", as they await his coming in glory. It is the duty of the consecrated life to show that the Incarnate Son of God is the eschatological goal towards which all things tend, the splendour before which every other light pales, and the infinite beauty which alone can fully satisfy the human heart. In the consecrated life, then, it is not only a matter of following Christ with one's whole heart, of loving him "more than father or mother, more than son or daughter" (cf. Mt 10:37) --- for this is required of every disciple --- but of living and expressing this by conforming one's whole existence to Christ in an all-encompassing commitment which foreshadows the eschatological perfection, to the extent that this is possible in time and in accordance with the different charisms. By professing the evangelical counsels, consecrated persons not only make Christ the whole meaning of their lives but strive to reproduce in themselves, as far as possible, "that form of life which he, as the Son of God, accepted in entering this world." By embracing chastity, they make their own the pure love of Christ and proclaim to the world that he is the Only-Begotten Son who is one with the Father (cf. Jn 10:30, 14:11). By imitating Christ's poverty, they profess that he is the Son who receives everything from the Father, and gives everything back to the Father in love (cf. Jn 17:7, 10). By accepting, through the sacrifice of their own freedom, the mystery of Christ's filial obedience, they profess that he is infinitely beloved and loving, as the One who delights only in the will of the Father (cf. Jn 4:34), to whom he is perfectly united and on whom he depends for everything.By this profound "configuration" to the mystery of Christ, the consecrated life brings about in a special way that confessio Trinitatis which is the mark of all Christian life; it acknowledges with wonder the sublime beauty of God, Father, Son and Holy Spirit, and bears joyful witness to his loving concern for every human being.
