Evil too, will always be part of the mystery of the Church. And when we see what men, what the clergy have done in the Church, then that is nothing short of proof that he [Christ] founded and upholds the Church. If she were dependent on men, she would long since have perished.

Those who with God's help have welcomed Christ's call and freely responded to it are urged on by love of Christ to proclaim the Good News everywhere in the world.
