World Day of Peace (Roman Catholic Church – initiated by Pope Paul VI)

What is World Day of Peace initiated by Pope Paul VI?

The World Day of Peace is an annual observance initiated by the Roman Catholic Church, celebrated on January 1st, coinciding with the Solemnity of Mary, Mother of God. Established by Pope Paul VI in 1967, it is a day dedicated to prayer, reflection, and commitment to peace at personal, national, and global levels. While it originated in the Catholic Church, the message and intent of the day are addressed to all people of goodwill, regardless of faith, and emphasize the Church’s ongoing mission to promote justice, human dignity, and nonviolence in a troubled world.

The World Day of Peace stands as a cornerstone of the Catholic Church’s commitment to peace through justice, truth, and love. In the words of Pope Paul VI, who famously said:

“If you want peace, work for justice.”

This day continues to challenge and inspire individuals, communities, and nations to become active peacemakers in a world still plagued by conflict and division.

The history behind the World Day of Peace celebration

The World Day of Peace was first celebrated on January 1, 1968, in response to the global turbulence of the 1960s—a time marked by the Vietnam War, the Cold War, civil rights struggles, and nuclear tensions. Recognizing the Church’s moral obligation to advocate for peace, Pope Paul VI proposed the day in a letter dated December 8, 1967, encouraging Catholics and all people to reflect on the urgent need for peace.

Pope Paul VI believed that the beginning of the civil year, a time of resolutions and renewal, was the ideal occasion to dedicate a day to the cause of peace. His message became the first in a tradition of annual papal messages for the World Day of Peace, each addressing contemporary issues such as war, poverty, the environment, human rights, migration, and disarmament.

Since then, every pope—from Saint John Paul II to Pope Benedict XVI, and now Pope Francis—has continued the tradition, issuing a World Day of Peace message each year that offers both spiritual guidance and policy reflections on the pursuit of peace in the modern world.
