1. Jesus Christ is the face of the Father's mercy. These words might well sum up the mystery of the Christian faith. Mercy has become living and visible in Jesus of Nazareth, reaching its culmination in him. The Father, "rich in mercy" (Eph 2:4), after having revealed his name to Moses as "a God merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness" (Ex 34:6), has never ceased to show, in various ways throughout history, his divine nature. In the "fullness of time" (Gal 4:4), when everything had been arranged according to his plan of salvation, he sent his only Son into the world, born of the Virgin Mary, to reveal his love for us in a definitive way. Whoever sees Jesus sees the Father (cf. Jn 14:9). Jesus of Nazareth, by his words, his actions, and his entire person[1] reveals the mercy of God.
2. We need constantly to contemplate the mystery of mercy. It is a wellspring of joy, serenity, and peace. Our salvation depends on it. Mercy: the word reveals the very mystery of the Most Holy Trinity. Mercy: the ultimate and supreme act by which God comes to meet us. Mercy: the fundamental law that dwells in the heart of every person who looks sincerely into the eyes of his brothers and sisters on the path of life. Mercy: the bridge that connects God and man, opening our hearts to the hope of being loved forever despite our sinfulness.
3. At times we are called to gaze even more attentively on mercy so that we may become a more effective sign of the Father's action in our lives. For this reason I have proclaimed an Extraordinary Jubilee of Mercy as a special time for the Church, a time when the witness of believers might grow stronger and more effective.
The Holy Year will open on 8 December 2015, the Solemnity of the Immaculate Conception. This liturgical feast day recalls God's action from the very beginning of the history of mankind. After the sin of Adam and Eve, God did not wish to leave humanity alone in the throes of evil. And so he turned his gaze to Mary, holy and immaculate in love (cf. Eph 1:4), choosing her to be the Mother of man's Redeemer. When faced with the gravity of sin, God responds with the fullness of mercy. Mercy will always be greater than any sin, and no one can place limits on the love of God who is ever ready to forgive. I will have the joy of opening the Holy Door on the Solemnity of the Immaculate Conception. On that day, the Holy Door will become a Door of Mercy through which anyone who enters will experience the love of God who consoles, pardons, and instils hope.
On the following Sunday, the Third Sunday of Advent, the Holy Door of the Cathedral of Rome - that is, the Basilica of Saint John Lateran - will be opened. In the following weeks, the Holy Doors of the other Papal Basilicas will be opened. On the same Sunday, I will announce that in every local church, at the cathedral - the mother church of the faithful in any particular area - or, alternatively, at the co-cathedral or another church of special significance, a Door of Mercy will be opened for the duration of the Holy Year. At the discretion of the local ordinary, a similar door may be opened at any shrine frequented by large groups of pilgrims, since visits to these holy sites are so often grace-filled moments, as people discover a path to conversion. Every Particular Church, therefore, will be directly involved in living out this Holy Year as an extraordinary moment of grace and spiritual renewal. Thus the Jubilee will be celebrated both in Rome and in the Particular Churches as a visible sign of the Church's universal communion.
