International Day of Peace: A Call to Build a More Peaceful World

September 21, 2026: Every year on September 21, the world observes the International Day of Peace, a day dedicated to promoting peace, non-violence, reconciliation and efforts to build a more peaceful world.

At a time when conflicts, social divisions and tensions continue to affect communities across the world, the day draws attention to the importance of peaceful approaches and sustained efforts towards reconciliation.

Why September 21 Matters

The International Day of Peace provides an opportunity to focus on the importance of peace and non-violence. It also highlights the role of reconciliation in building societies where people can live together with dignity and mutual respect.

The observance places peace at the centre of public attention, reminding individuals, communities and institutions of the importance of efforts that contribute to a more peaceful world.

Peace Beyond Words

Building peace involves more than simply speaking about it. It requires efforts towards reconciliation, non-violence, dialogue and the creation of communities where differences can be addressed without resorting to hostility or violence.

The International Day of Peace highlights these efforts and encourages continued attention to the work of building peace at local, national and international levels.

The Contribution of Churches

Churches contribute to peace through prayer, advocacy, dialogue and community action. The World Council of Churches calls upon churches globally to observe September 21 as the International Day of Prayer for Peace, coinciding with the UN International Day of Peace.

Many Christian denominations also observe the Sunday closest to September 21 as Just Peace Sunday, focusing on prayer, theological reflection and community action directed towards non-violence, peacemaking and justice.

Churches contribute through local and global advocacy, organised prayer, community peacebuilding programmes and efforts towards reconciliation.

Peacebuilding in the Indian Context

The Catholic Church in India has also expressed its commitment to peace through concrete initiatives. At the CCBI National Synodal Assembly 2026, held in Bengaluru in May, Interreligious dialogue and peacebuilding was identified as one of four key themes for reflection. The priority recognised the importance of dialogue, mutual understanding and collaboration among people of different faiths in India's religiously diverse society.

The CCBI has also supported communities affected by conflict. During the violence in Manipur, the CCBI Commission for Migrants, in collaboration with the International Catholic Migration Commission, supported people displaced by the conflict through programmes addressing both immediate and longer-term needs.

In 2025, a mental-wellbeing programme was organised for people living in relief camps, with 63 participants taking part. Volunteers were also trained to extend support within their communities. CCBI-supported programmes have included basic-needs assistance, livelihood support, psychosocial care and educational support, helping displaced people work towards rebuilding their lives with greater dignity and self-reliance.

Prayer has also formed part of the Church's response to the conflict. In 2023, the CBCI called for a national day of prayer for peace in Manipur, asking Catholic communities across India to pray for peace and harmony and encouraging Eucharistic Adoration and other prayer initiatives.

These efforts demonstrate that peacebuilding can take different forms—from dialogue and prayer to humanitarian assistance and accompanying communities affected by conflict.

The Catholic Church’s World Day of Peace

The Catholic Church has a dedicated World Day of Peace, observed on January 1. It was instituted by Pope Paul VI in 1967.

Each year, popes issue messages for the World Day of Peace, addressing issues related to human dignity, justice, international relations, disarmament, reconciliation and non-violence.

A Continuing Effort

The International Day of Peace is an opportunity to keep attention focused on peace, non-violence and reconciliation. Peace is not built only through agreements between governments or negotiations during conflicts. It is also built through dialogue between communities, support for those affected by violence, prayer, reconciliation and everyday efforts to uphold human dignity.

For Christians, the pursuit of peace remains both a spiritual commitment and a practical responsibility—one expressed through prayer, dialogue, service and the patient work of rebuilding relationships and communities.
