Benedict XVI: “There can only be responsibility where there is someone to be responsible to”
“Anyone who entrusts himself to a life of faith becomes aware that both exist: the radical character of grace that frees helpless man and,no less, the abiding seriousness of the responsibility that summons man day after day. Both together mean that the Christian enjoys, on the one hand, the liberating, detached tranquility of him who lives on that excess of divine justice known as Jesus Christ. … This is the source of a profound freedom, a knowledge of God’s unrepentant love; he sees through all our errors and remains well disposed to us…
At the same time, the Christian knows, however, that he is not free to do whatever he pleases, that his activity is not a game that God allows him and does not take seriously. He knows that he must answer for his actions, that he owes an account as a steward of what has been entrusted to him. There can only be responsibility where there is someone to be responsible to, someone to put the questions.
Faith in the Last Judgment holds this questioning of our life over our heads so that we cannot forget it for a moment. Nothing and no one empowers us to trivialize the tremendous seriousness involved in such knowledge; it shows our life to be a serious business and precisely by doing so gives it its dignity.”
