Whenever we Christians are enclosed in our groups, our movements, our parishes, in our little worlds, we remain closed, and the same thing happens to us that happens to anything closed: 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 the same thing that can happen to anyone out there: an accident. How often have we 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. And sometimes he or she is not well in the head . . .
But, careful! Jesus does not say, Go off and do things on your own. No! That is not what he is saying. Jesus says, Go, for I am with you! This is what is so beautiful for us; it is what guides us. If we go out to bring his Gospel with love, with a true apostolic spirit, with parrhesia, he walks with us, he goes ahead of us and he gets there first.
