In reality, St. Paul's conversion was not a passage from immorality to morality, from a mistaken faith to a right faith, but it was a being conquered by Christ: the renunciation of his own perfection; it was the humility of one who puts himself without reserve in the service of Christ for the brethren. And only in this renunciation of ourselves, in this conforming to Christ, are we also united among ourselves; we become "one" in Christ. It is communion with the risen Christ that gives us unity.
--Pope Benedict XVI, June 25, 2009
