VATICAN CITY — Pope Leo XIV remembered the victims of the Sept. 11, 2001, terrorist attacks on Sunday and renewed his appeal for peace amid conflicts and violence around the world.

Speaking in English after praying the Angelus with the faithful gathered in St. Peter’s Square on Sept. 13, the pope recalled the 25th anniversary of the attacks, which was observed two days earlier.

“Two days ago marked the 25th anniversary of the Sept. 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,” he said.

Continuing in Italian, Leo said the memory of the tragedy should prompt a renewed commitment to peace, above all through prayer entrusted to the intercession of the Virgin Mary.

The pope then greeted the Romans and pilgrims gathered in the square, including groups from Brazil and other countries, pilgrims who had traveled from Assisi along the Way of St. Francis, and motorcyclists gathered in support of peace and life.

Earlier, in his reflection before the Angelus, Leo focused on the Sunday Gospel and the Christian meaning of forgiveness, recalling that Christ taught forgiveness and bore witness to it even on the cross, when he prayed to the Father for his persecutors.

Reflecting on Peter’s question to Jesus about how many times he should forgive someone who sins against him, the pope noted that Peter’s suggestion of seven times already indicated abundance, since the number seven symbolizes fullness in Scripture. Jesus, however, went further, telling him to forgive “70 times seven” — without limit or measure.

Leo then recalled the parable of the servant whose enormous debt was forgiven by his master but who refused to show the same mercy to a fellow servant who owed him far less.

“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,” the pope said.

“We experience this every day. Forgiveness is indispensable, and without it, we cannot live in peace.”

Without forgiveness, Leo warned, conflicts, accusations, grudges and acts of vengeance eventually arise, destroying relationships, dividing families and unleashing 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,” he said.

The pope also pointed to St. Peter’s own experience of forgiveness after denying and abandoning Jesus during the Passion. When Peter encountered the risen Christ on the shore of the Sea of Galilee, Jesus asked him only whether he loved him and once again called him to follow.

Leo said that forgiving and healing love confirmed Peter in his mission as the first of the apostles.

Concluding his reflection, the pope asked the Virgin Mary, Mother of Mercy, to help Christians forgive even when taking the first step is difficult, and to spread the healing light of a love that overcomes hatred and disarms resentment.
