Celebrated every year on the second-to-last Sunday of October, World Mission Sunday is the day when Catholics around the world unite to support the missionary work of the Church. Established by Pope Pius XI in 1926, it remains the only annual global collection that directly supports mission territories where the Church is young, struggling, or persecuted. On this day, every parish, in every diocese, in every country, joins in prayer and giving to ensure that missionaries can continue their vital work—building churches, forming priests, supporting catechists, and serving communities in need.

This year, World Mission Sunday is October 19, 2025.

This year’s theme reminds us that hope is at the heart of the Christian mission, calling every baptized person to be “Missionaries of Hope Among All Peoples.” Join us in this universal mission to spread the Gospel and invite all to experience the joy of Christ’s message!
