"At the beginning of the new millennium, and at the close of the Great Jubilee during which we celebrated the two thousandth anniversary of the birth of Jesus and a new stage of the Church's journey begins, our hearts ring out with the words of Jesus when one day, after speaking to the crowds from Simon's boat, he invited the Apostle to "put out into the deep" for a catch: "Duc in altum" (Lk 5:4). Peter and his first companions trusted Christ's words, and cast the nets. "When they had done this, they caught a great number of fish" (Lk 5:6). Duc in altum! These words ring out for us today, and they invite us to remember the past with gratitude, to live the present with enthusiasm and to look forward to the future with confidence: "Jesus Christ is the same yesterday and today and for ever" (Heb 13:8)."
