World Mission Sunday is the second to last Sunday of October and celebrates the deepest identity of the Church in mission, according to the bulletin from Saints Joseph, Peter, Boniface, and Assumption of the Blessed Virgin Mary Parish Cluster.

This day is set aside by Catholics around the world to reflect on the day they received the gift of faith – their baptism – and to recommit themselves to the Catholic Church and its mission. 

"It 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 the all the missions of the world.' Pope John Paul II has also spoken of the Propagation of the Faith's General Fund of support, calling this a 'central fund of solidarity,'" the church said in the bulletin. "In a message delivered on a recent World Mission Sunday, the Pope said: 'The offerings that will be collected [on World Mission Sunday] are destined for a common fund of solidarity distributed, in the Pope's name, by the Society for the Propagation of the Faith among the missions and missionaries of the entire world.'"

Each year, the mission of the church grows as new dioceses and churches are formed and more priests join the church. 

"That is why the involvement and commitment of Catholics from around the world is so urgently needed. Offerings from Catholics in the United States, on World Mission Sunday and throughout the year, are combined with offerings to the Propagation of the Faith worldwide," the church said in the bulletin.
