Whenever Christians are enclosed in their groups, parishes, and movements. If a Christian goes to the streets, or to the outskirts, he or she may risk the same thing that can happen to anyone out there: an accident. How often we have seen accidents on the road! But I am telling you: I would prefer a thousand times over a bruised Church to an ill Church! A Church, a catechist, with the courage to risk going out, and not a catechist who is studious, who knows everything but is always closed—such a person is not well.
--Pope Francis, Address to the Participants at the International Congress on Catechesis, September 27, 2013.
