World Mission Day 2026

ONE IN CHRIST, UNITED IN MISSION

Sunday, October 18, 2026

World Mission Day was first established by Pope Pius XI, beginning in October 1927. This year the Church celebrates the 100th World Mission Day on Sunday, October 18, 2026. As the Church prepares to celebrate this day, Pope Leo XIV calls us to unity in Christ, love, and renewed missionary commitment "with joy and zeal in the Holy Spirit" in his first World Mission Sunday Message: “One in Christ, united in mission."

Following the Jubilee Year, I wish to encourage the whole Church to continue its missionary journey with joy and zeal in the Holy Spirit. This requires hearts united in Christ, reconciled communities and, in everyone, a willingness to cooperate with generosity and trust.

Pope Leo XIV, Message for the 100th World Mission SUnDay (October 2026)

[Christ] was known before the foundation of the world but revealed in the final time for you, who through him believe in God who raised him from the dead and gave him glory, so that your faith and hope are in God.

1 Peter 1:20-21

On World Mission Sunday, we join our Holy Father in supporting his missions. As we pray and respond here at home, we share in those celebrations taking place in every parish and diocese throughout the world. Together, through our prayers and financial support, we bring the Lord’s mercy and concrete help to the most vulnerable communities in the Pope’s missions.

World Mission Sunday rejoices in our unity as missionaries by our Baptism, as it offers each one of us an opportunity to support the life-giving presence of the Church among the poor and marginalized in more than 1,150 mission dioceses. WITH GRATEFUL HEARTS FOR YOUR MISSION SOLIDARITY!
