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 so this year it will be celebrated over the weekend of Sunday 23rd.

The theme for this year’s celebration of Mission Sunday is: “You Shall Be My Witnesses” (Acts 1:8).

On World Mission Sunday, collections will take place at Masses throughout the universal Church so that Catholics might give what they can to help support struggling dioceses in the developing world. The Mission Sunday collection promotes the work of missionaries in poor and remote communities. The funds raised will help build vital infrastructure, including churches, medical clinics, nurseries and schools.

At 11:00am on 23 October, RTÉ will televise the celebration of Mass from its Donnybrook studio, Dublin, for World Mission Sunday.
