“Today the Church lays great stress on this truth, confirmed by the history of every man. Remember that “to dust you shall return”. Remember that your life on earth has a limit!… Therefore the message of Ash Wednesday is expressed with the words of St. Paul: “We are ambassadors for Christ, God making his appeal through us. We beseech you on behalf of Christ, be reconciled to God. For our sake, he made him to be sin who knew no sin, so that in him we might become the righteousness of God” (2 Cor 5:20-21). Collaborate with him!” St. John Paul II
