Dr. Tom Catena, a Catholic lay missionary from the United States, examines a patient during rounds at the Mother of Mercy Hospital in Gidel, a village in the Nuba Mountains of Sudan, April 26, 2018. Pope Francis told the pontifical mission societies in a message May 21, 2020, that those involved with the church's missionary activity "should never justify their lack of concern for the poor with the excuse, widely used in particular ecclesiastical circles, of having to concentrate their energies on certain priorities for the mission."
