In 2006, Pope Benedict XVI said "The mystery of God's merciful love was at the centre of the pontificate of my venerated predecessor." He recommended that the faithful read his homily dedicating the Shrine of Divine Mercy in Poland. Kraków-Łagiewniki, 17 August 2002. (Found here at Vatican website) Here are some excerpts from that homily, with some passages I have highlighted with underline:
"O inconceivable and unfathomable Mercy of God, Who can worthily adore you and sing your praises? O greatest attribute of God Almighty, You are the sweet hope of sinners" (Diary, 951).
Dear Brothers and Sisters! 1. Today I repeat these simple and straightforward words of Saint Faustina, in order to join her and all of you in adoring the inconceivable and unfathomable mystery of God’s mercy. Like Saint Faustina, we wish to proclaim that apart from the mercy of God there is no other source of hope for mankind. We desire to repeat with faith: Jesus, I trust in you! This proclamation, this confession of trust in the all-powerful love of God, is especially needed in our own time, when mankind is experiencing bewilderment in the face of many manifestations of evil. The invocation of God’s mercy needs to rise up from the depth of hearts filled with suffering, apprehension and uncertainty, and at the same time yearning for an infallible source of hope.
That is why we have come here today, to this Shrine of Łagiewniki, in order to glimpse once more in Christ the face of the Father: "the Father of mercies and the God of all consolation" (2 Cor 1:3). With the eyes of our soul, we long to look into the eyes of the merciful Jesus, in order to find deep within his gaze the reflection of his inner life, as well as the light of grace which we have already received so often, and which God holds out to us anew each day and on the last day. . . .
"But the hour is coming, and now is, when true worshippers will worship the Father in spirit and truth, for such the Father seeks to worship him" (Jn 4:23). When we read these words of the Lord Jesus here in the Shrine of Divine Mercy, we are particularly aware that no one can come here except in Spirit and truth. It is the Holy Spirit, the Comforter and the Spirit of Truth, who guides us along the ways of Divine Mercy. By convincing the world "concerning sin and righteousness and judgement" (Jn 16:8), he also makes known the fullness of salvation in Christ. This "convincing" concerning sin is doubly related to the Cross of Christ. On the one hand, the Holy Spirit enables us, through Christ’s Cross, to acknowledge sin, every sin, in the full dimension of evil which it contains and inwardly conceals. On the other hand, the Holy Spirit permits us, again through the Christ’s Cross, to see sin in the light of the mysterium pietatis, that is, of the merciful and forgiving love of God (cf. Dominum et vivificantem, 32). Consequently, this "convincing concerning sin" also becomes a conviction that sin can be laid aside and that man can be restored to his dignity as a son beloved of God. Indeed, the Cross "is the most profound condescension of God to man [...]. The Cross is like a touch of eternal love upon the most painful wounds of man’s earthly existence" (Dives in misericordia, 8).
The cornerstone of this Shrine will always be a reminder of this truth, for it was brought here from Mount Calvary, as if from beneath the Cross on which Jesus Christ triumphed over sin and death. I firmly believe that this new church will always be a place where people will come before God in Spirit and truth. They will come with the trust which accompanies all those who humbly open their hearts to the working of God’s merciful love, to that love which is stronger than even the greatest sin. Here, in the fire of divine love, human hearts will burn with desire for conversion, and whoever looks for hope will find comfort.
"Eternal Father, I offer to you the Body and Blood, Soul and Divinity of your beloved Son, our Lord Jesus Christ, for our sins and those of the whole world; by the sufferings of his Passion, have mercy upon us and upon the whole world" (Diary, 476). Upon us and upon the whole world ... How greatly today’s world needs God’s mercy! In every continent, from the depth of human suffering, a cry for mercy seems to rise up. Where hatred and the thirst for revenge dominate, where war brings suffering and death to the innocent, there the grace of mercy is needed in order to settle human minds and hearts and to bring about peace. Wherever respect for life and human dignity are lacking, there is need of God’s merciful love, in whose light we see the inexpressible value of every human being. Mercy is needed in order to ensure that every injustice in the world will come to an end in the splendour of truth.
Today, therefore, in this Shine, I wish solemnly to entrust the world to Divine Mercy. I do so with the burning desire that the message of God’s merciful love, proclaimed here through Saint Faustina, may be made known to all the peoples of the earth and fill their hearts with hope. May this message radiate from this place to our beloved homeland and throughout the world. May the binding promise of the Lord Jesus be fulfilled: from here there must go forth "the spark which will prepare the world for his final coming" (cf. Diary, 1732). This spark needs to be lighted by the grace of God. This fire of mercy needs to be passed on to the world. In the mercy of God the world will find peace and mankind will find happiness! I entrust this task to you, dear Brothers and Sisters, to the Church in Kraków and Poland, and to all the votaries of Divine Mercy who will come here from Poland and from throughout the world. May you be witnesses to mercy!
God, merciful Father, in your Son, Jesus Christ, you have revealed your love and poured it out upon us in the Holy Spirit, the Comforter, We entrust to you today the destiny of the world and of every man and woman. Bend down to us sinners, heal our weakness, conquer all evil, and grant that all the peoples of the earth may experience your mercy. In You, the Triune God, may they ever find the source of hope. Eternal Father, by the Passion and Resurrection of your Son, have mercy on us and upon the whole world! Amen.
