Since 1926, the Church has traditionally remembered its universal mission during the month of October. This year Mission Sunday will be celebrated globally on the 22nd October 2017. The theme is 'Reach Out, Spread the Joy.' Throughout the world the faithful will reflect on the universal call to Mission of all the baptised. They will be invited to contribute what they can to support the development and growth of young churches internationally. Mission Sunday is celebrated by every Church worldwide, including the poorest.

This special Sunday in October provides Catholics with the opportunity to unite with their missionary sisters and brothers overseas, and to recommit themselves to bringing the Joy of the Gospel to everyone they meet in their daily lives at home and at work.
