Whenever we Christians are enclosed in our groups, our movements, our parishes, and the same thing happens to us that happens to anything close: when a room is closed, it begins to get dank. If a person is closed up in that room, he or she becomes ill! Whenever Christians are enclosed in their groups, parishes, and movements, they take ill. If a Christian goes to the streets, or to the outskirts, he or she may risk an accident.
– Pope Francis, The Church of Mercy
