The World Interfaith Harmony Week (WIHW), proclaimed by the United Nations General Assembly in 2010, provides a global framework to encourage dialogue and cooperation among religious communities around the world. Indonesia, represented by Center for Dialogue and Cooperation among Civilizations (CDCC) and Inter Religious Council (IRC) Indonesia have demonstrated the strong commitment to maintaining national unity and harmony, by consistently participating in the Celebration of the World Interfaith Harmony Week since 2011. The 2018 WIHW Celebration, 450 religious leaders from across Indonesia gathered to deliberate on strategic national issues and adopted a declaration reaffirming their shared commitment to peace, harmony, and national unity. The celebration also involved large public participation, bringing together thousands of people in a national event that highlighted interfaith dialogue, cultural performances, and collective expressions of unity. These experiences demonstrate that interfaith initiatives in Indonesia are not merely symbolic events but meaningful platforms that encourage dialogue, reflection, and collaborative action among religious communities and broader society.

Within this framework, the 2026 commemoration emphasizes three interconnected dimensions. First, environmental stewardship is highlighted through an interfaith environmental initiative involving the planting of trees by communities from the six major religions in Indonesia at houses of worship across various regions of the country. This collective action reflects the shared ethical teachings of religious traditions that emphasize responsibility for protecting the Earth and preserving the natural environment for future generations.

Second, cultural engagement is promoted as a means of strengthening dialogue and mutual understanding. Cultural expressions such as artistic performances, music, and interfaith cultural activities serve as bridges that connect communities while celebrating the diversity that characterizes Indonesian society.

Third, the theme places particular emphasis on peacemaker regeneration, recognizing the importance of nurturing a new generation of leaders who are committed to promoting dialogue, tolerance, and peaceful coexistence. As part of this effort, the program includes an Interfaith Youth Training for Harmony and Collaboration, designed to empower young people from different religious backgrounds with the knowledge, skills, and networks necessary to become agents of peace within their communities.

Through these initiatives, the 2026 commemoration seeks to strengthen the foundations of interfaith harmony by linking environmental responsibility, cultural dialogue, and youth leadership, ensuring that the values of peace and fraternity continue to flourish across generations.
