Dear brothers and sisters, Happy Sunday!

Today's Gospel speaks to us of forgiveness, which is a fundamental feature of the Christian life. Jesus taught and exemplified forgiveness even on the cross, where he prayed to the Father for his persecutors with the familiar words: "Forgive them, for they do not know what they are doing" (Lk 23:34).

In today's passage, Peter asks the Master precisely about this question: "Lord, how often shall my brother sin against me, and I forgive him? As many as seven times?" (Mt 18:21). His words reveal a generous heart, for the number seven symbolizes fullness in the Bible, and "forgiving seven times" means forgiving abundantly. Jesus' response, however, goes even further: "I do not say to you seven times, but seventy times seven" (v. 22); in other words, beyond all limits, without measure.

To clarify his point further, the Savior tells the parable of a servant who owed his master a large debt that was practically impossible to pay. Although his own debt was forgiven out of pure mercy, he did not extend the same mercy toward one of his fellow servants, and for this he was rebuked and severely punished (vv. 23-30).

With these words, Jesus reminds us that gift and forgiveness are the foundation of our existence. All things are given to us by God out of pure love, and none of us can claim to be perfect in responding to such goodness. For this reason, gratuitousness — which is the source of our existence — is also the best rule for our life together. We experience this every day. Forgiveness is indispensable, and without it, we cannot live in peace. Sooner or later conflicts, accusations, grudges and acts of vengeance emerge in our hearts and among people, and these acts destroy relationships, divide families and unleash wars.

Only forgiveness sets us free and restores the light, even where human material and moral poverty has darkened the horizon and made the path uncertain. Forgiveness, like a gentle breeze, sweeps away even the thickest clouds until the sun shines once more. Saint Peter himself experienced this many times in his life; in particular, when — after denying and abandoning Jesus during the Passion — he encountered the risen Lord on the shore of the lake and heard him ask just one question: "Simon … do you love me?" (Jn 21:15). This was accompanied by an invitation, "follow me!" (v. 19), which was the same invitation given on the occasion of their first encounter. It was as if nothing had happened. This love, which forgives and heals, would mark for the first of the Apostles, the confirmation of his mission.

Let us therefore ask the Virgin Mary, Mother of Mercy, to help us forgive — always, even when it is difficult to take the first step — and to spread, with courage and perseverance, the serene and healing light of love that overcomes hatred and disarms all resentment.

Dear brothers and sisters!

Two days ago marked the twenty-fifth anniversary of the September 11th terrorist attacks in the United States of America. I renew my prayers for those who lost their lives and for those who continue to bear the wounds of that tragic day. At a time when conflict and violence afflict so many of our brothers and sisters, I invite everyone to pray that the Lord will bestow his gift of peace upon the world.

The memory of the tragic event that took place twenty-five years ago prompts us to renew our commitment to peace, first and foremost through prayer, which we entrust to the intercession of the Virgin Mary.

Now I warmly greet all of you, Romans and pilgrims!

I welcome the groups from São Paulo, Brazil, and those from various other countries.

I greet the members of the Jesus Nazareno Cautivo Religious Association living in Rome, the group from the Salesian Oratory in Chieri, the faithful from Dolianova, Sardinia, and the pilgrims who have come from Assisi along the Way of Saint Francis.

I greet the "Bellunese Family" along with the Erechim School in Brazil, as well as the motorcyclists who have gathered to show their support for peace and life.

I wish everyone a happy Sunday.
