Taken from The Liturgical Year by Dom Prosper Guéranger  (1841-1875)

Quote:Francis, fourth Duke of Gandia, was the son of John Borgia and of Joanna of Aragon, grand-daughter of Ferdinand the Catholic. He passed his childhood, in his father’s house, in wonderful innocence and piety; but appeared still more admirable when he showed himself a pattern of Christian virtue and austerity, first at the court of the Emperor, Charles V, and afterwards as viceroy of Catalonia. He was charged to convey the body of the Empress Isabelle to her sepulcher at Granada. Seeing the horrible change in her features, he understood how fleeting are all earthly things, and vowed to renounce every thing as soon as possible, and devote himself to the service of the King of kings. From that day forward he made such progress in virtue that, in the midst of overwhelming occupations, his life was a faithful copy of religious perfection, so that he was called the miracle of princes.

On the death of his wife Eleonora de Castro, he entered the Society of Jesus, that he might therein be more hidden, on account of the vow which closes the door to ecclesiastical preferment. Many princes followed him in embracing a severe manner of life; and Charles V himself did not hesitate to acknowledge that his advice and example had led him to abdicate the throne. Francis devoted himself to the exercises of a penitential life, and macerated his body by fasting, iron chains, a rough hair-shirt, long and bloody disciplines, allowing himself very little sleep; while at the same time he spared no effort to conquer himself and to gain souls. His great virtue caused St. Ignatius to appoint him Commissary general for Spain; and soon afterwards, against his will, he was chosen by the whole Society third General of the Order. In this position his prudence and holiness endeared him both to Popes and to temporal rulers. He founded and enlarged many houses of his Order, and introduced the Society into Poland, the islands of the Atlantic, Mexico, and Peru, and sent apostolic men into other regions who spread the Catholic, Roman faith by their preaching, their labors, and their blood.

He had a most lowly opinion of himself, always calling himself the sinner. This humility led him to persistently refuse the Roman purple, which was more than once offered him by the Pope. Filled with contempt for himself and the world, he delighted in sweeping away dirt, begging alms from door to door, and serving the sick in the hospitals. He devoted many hours every day to heavenly contemplation, spending sometimes eight or even ten hours in prayer, and genuflecting in adoration a hundred times in the day. He never omitted saying Mass. While he was offering the divine Victim, or preaching, the heavenly ardor which consumed him betrayed itself by the radiance of his countenance. He knew by a heavenly instinct where the most holy Body of Christ, hidden in the Eucharist, was kept. Saint Pius V appointed Francis companion to Cardinal Alessandrino, in an embassy for uniting the Christian princes against the Turks. Although his strength was almost exhausted, he undertook this journey in obedience; but on the way he happily closed his life, as he had wished, at Rome, in the sixty-second year of his age, and in the year of salvation 1572. By Saint Teresa, who had often sought his advice, he was called a saint, and by Gregory XIII a faithful servant of God. Finally, after many great miracles, he was canonized by Clement X.
