1. The World Day of Peace this year is being celebrated in the shadow of the dramatic events of 11 September last. On that day, a terrible crime was committed: in a few brief hours thousands of innocent people of many ethnic backgrounds were slaughtered. Since then, people throughout the world have felt a profound personal vulnerability and a new fear for the future. Addressing this state of mind, the Church testifies to her hope, based on the conviction that evil, the mysterium iniquitatis, does not have the final word in human affairs. The history of salvation, narrated in Sacred Scripture, sheds clear light on the entire history of the world and shows us that human events are always accompanied by the merciful Providence of God, who knows how to touch even the most hardened of hearts and bring good fruits even from what seems utterly barren soil.
This is the hope which sustains the Church at the beginning of 2002: that, by the grace of God, a world in which the power of evil seems once again to have taken the upper hand will in fact be transformed into a world in which the noblest aspirations of the human heart will triumph, a world in which true peace will prevail.
Peace: the work of justice and love
2. Recent events, including the terrible killings just mentioned, move me to return to a theme which often stirs in the depths of my heart when I remember the events of history which have marked my life, especially my youth.
The enormous suffering of peoples and individuals, even among my own friends and acquaintances, caused by Nazi and Communist totalitarianism, has never been far from my thoughts and prayers. I have often paused to reflect on the persistent question: how do we restore the moral and social order subjected to such horrific violence? My reasoned conviction, confirmed in turn by biblical revelation, is that the shattered order cannot be fully restored except by a response that combines justice with forgiveness. The pillars of true peace are justice and that form of love which is forgiveness.
[Pope John Paul II, Message for the xxxv World Day of Peace]
