History of World Mission Sunday
World Mission Sunday was established by Pope Pius XI in 1926 as a day of prayer and support for the global missionary activity of the Church. Over the decades, the observance has grown to include solidarity collections, missionary awareness campaigns, prayer, and formation materials promoted by the Pontifical Mission Societies (also known as Missio).
The Pontifical Mission Societies coordinate much of the promotion, resources, and pastoral outreach related to World Mission Sunday, offering parishes support in liturgy, catechesis, and fundraising to aid mission territories.
Why World Mission Sunday is important
World Mission Sunday underscores that the Church is by nature missionary: it looks outward, beyond its own borders, to share the Gospel, serve communities, and support fledgling or underprivileged churches. On this day, Catholics around the world pause to remember that mission is not merely a function of some, but a shared responsibility of all the baptized.
World Communion Sunday
In addition, the day raises awareness of communities in mission territories—places where the Church is young, poor, struggling, or facing persecution—and invites not just prayer, but material support for pastoral, educational, health, and social initiatives. The offerings collected on World Mission Sunday often fund schools, health care, church buildings, formation of clergy and laity, and essential services in mission dioceses.

How to Observe World Mission Sunday
Make it yours
How would you like to spend World Mission Sunday?
Tick what fits you, and we will put together ideas made for this day — not for any day.
Parishes typically integrate the day into the liturgical celebration: the Masses may include a special collection (the Mission Sunday Collection), prayers of the faithful for missions, and a homily highlighting missionary themes. Many dioceses provide posters, bulletin inserts, missionary stories, and educational materials.
Individuals can observe by praying for missionaries and mission territories, reading the Pope’s message for the year, sharing stories or testimonies from mission contexts, and contributing financially or in other ways (e.g. supporting missionary societies, volunteering, or promoting mission awareness in one’s community). In 2025, the theme chosen by Pope Francis for World Mission Sunday is “Missionaries of Hope Among all Peoples”.
- Participate in or support the Mission Sunday collection
- Read or reflect on the Pope’s annual mission message
