World Mission Sunday
October 21-22, 2023
In 1926 Pope Pius XI instituted Mission Sunday for the whole Church with the first worldwide Mission Sunday collection taking place in October 1927. The Mission Sunday collection is always taken on the next to last Sunday during the month of October. That day is celebrated in all the local Churches as the feast of catholicity and universal solidarity so Christians the world over will recognize their common responsibility with regard to the evangelization of the world.
