"If science does not devote itself to understanding and teaching life, it will lose the most decisive battles on the fascinating and mysterious ground of genetic engineering". This is one of the lessons of card. Trujillo, mentioned by the Pope during the homily for the funeral rites celebrated today in Saint Peter’s Basilica. "The late lamented cardinal said Benedict XVI drew his love for the truth of man and for the Gospel of the family from the thought that every human being and every family reflect the mystery of God who is Love. Everyone will still remember recalled the Pontiff his moving speech at the Assembly of the Synod of the Bishops in 1997: it was a veritable song to life". If card. López Trujillo "has made the defence of and love for the family the distinctive commitment of his service", according to the Pope, "it is to the statement of the truth that he has devoted his entire life", both in Colombia and in Rome, when he devoted himself to "exploring, proclaiming and spreading the Gospel of life and the Gospel of the family", convinced as he was of the "value of this decisive fight for the Church and for mankind". His "generosity", especially "for children in many parts of the world", must drive us "to spend every physical and spiritual resource of ours for the Gospel" and to "work for the defence of human life", concluded Benedict XVI.
