World Mission Sunday, organized by the Propagation of the Faith, is a day set aside for Catholics worldwide to recommit themselves to the Church’s missionary activity through prayer and sacrifice. In 2010, World Mission Sunday is celebrated on October 24.
Annually, World Mission Sunday is celebrated on the next-to-last Sunday in October. As described by Pope John Paul II, World Mission Sunday is “an important day in the life of the Church because it teaches how to give: as an offering made to God, in the Eucharistic celebration and for all the missions of the world” (see Redemptoris Missio 81).
