DEAR brothers and sisters, for World Mission Day 2026, which marks the centenary of a celebration established by Pope Pius XI that is very dear to the Church, I have chosen the theme 'One in Christ, united in mission.'

TO MARK World Mission Day on Sunday October 19, the Holy Father, Pope Leo XIV, is asking every single parish in the world to help support missionaries who are working and serving in the remotest corners of the earth.

For World Mission Day 2025, I have chosen the motto: "Missionaries of Hope Among all Peoples."
