Each year, Catholics around the world unite in prayer and generosity on World Mission Sunday, answering the call to share the Gospel and support the Church’s mission in more than 1,100 mission territories across Asia, Africa, Oceania, the Pacific Islands, and Latin America.
Established by Pope Pius XI in 1926, World Mission Sunday reminds the faithful that we are all missionaries — sent by Christ to bring His light and mercy to every corner of the world. This year, World Mission Sunday will be celebrated on October 19, 2025.
In his special video message for this year’s celebration, Pope Leo XIV urges Catholics everywhere to join him in supporting missionaries who bring the Gospel to those most in need.
“Help me help the missions,” Pope Leo says, inviting all of us to share in the Church’s missionary work through prayer and generosity.
