World Mission Sunday is the Holy Father’s annual appeal for spiritual and financial support so that the life-giving work of overseas mission and missionaries can continue. It always falls on the second last Sunday in October, and like the Good Friday collection for the Holy Land and Peter’s Pence, it is one of three yearly universal Church collections. It will replace the usual Share Collection next Sunday.
World Mission Sunday collections take place in every single parish where the Church is present. This includes not only Ireland and Europe, but also in poorer parishes in developing countries. It is a moment of universal solidarity when each member of the Church family, regardless of location or background, play their part in supporting each other. This is what makes it such a special celebration.
