From the talk given by Pope Benedict XVI before the Regina Caeli prayer at Castel Gandolfo on Sunday, March 30th 2012:
'During the Jubilee of the Year 2000 the beloved Servant of God John Paul II established that throughout the Church the Sunday after Easter should be called Domenica in Albis and Divine Mercy Sunday. This occurred contemporaneously with the canonization of Faustina Kowalska, a humble Polish Sister who was born in 1905 and died in 1938, a zealous messenger of the Merciful Jesus. Indeed, mercy is the central nucleus of the Gospel message; it is the very name of God, the Face with which he revealed himself in the Old Covenant and fully in Jesus Christ, the incarnation of creative and redemptive Love. May this merciful love also shine on the face of the Church and show itself through the sacraments, in particular that of Reconciliation, and in works of charity, both communitarian and individual. May all that the Church says and does manifest the mercy God feels for man, and therefore for us. When the Church has to recall an unrecognized truth or a betrayed good, she always does so impelled by merciful love, so that men and women may have life and have it abundantly (cf. Jn 10: 10). From divine mercy, which brings peace to hearts, genuine peace flows into the world, peace between different peoples, cultures and religions.
Like Sr Faustina, John Paul II in his turn made himself an apostle of Divine Mercy. In the evening of the unforgettable Saturday, 2 April 2005, when he closed his eyes on this world, it was precisely the eve of the Second Sunday of Easter and many people noted the rare coincidence that combined the Marian dimension - the first Saturday of the month - and the dimension of Divine Mercy. This was in fact the core of John Paul II's long and multi-faceted Pontificate. The whole of his mission at the service of the truth about God and man and of peace in the world is summed up in this declaration, as he himself said in Krakow-Łagiewniki in 2002 when he inaugurated the large Shrine of Divine Mercy: "Apart from the mercy of God there is no other source of hope for mankind". John Paul II's message, like St Faustina's, thus leads back to the Face of Christ, a supreme revelation of God's mercy. Constant contemplation of this Face is the legacy he bequeathed to us which we joyfully welcome and make our own.'
