The Society of the Propagation of the Faith has the goal of opening every believer's heart to the vastness of the missionary horizon through spiritual and material support for the proclamation of the Kingdom of God. Through a constant and vigorous commitment to missionary formation and animation it promotes missionary spirituality for evangelization. The Society has the task to urge the local Churches to be open to universal missionary cooperation and to distribute in the Pope's name what is collected around the world during World Mission Day.
The Society of St. Peter the Apostle promotes awareness in the Christian communities regarding the need to develop the local clergy and consecrated life in the recently founded missionary churches. It animates and coordinates missionary collaboration in all the local churches through the offering of prayers, sacrifices and money to support the formation of the future priests and the men and women religious of the young churches, and the necessary preparation of their formators.
