This saint was like a white and fragrant lily in his virgin purity, transplanted by God from the luxurious and sensual Court of Madrid to the chosen garden of St. Ignatius of Loyola at Rome.

The whole life of Aloysius breathes forth sanctity and purity; his Baptism, which was administered at the vary moment of his birth, his first communion at the hands of St. Charles Borromeo; his reception into the Society of Jesus by Claudio Acquaviva, the spiritual direction given to him at the College Romano by St. Robert Bellarmine; his severe penances, and lastly, his holy death as a victim of charity in the service of the plague-stricken sufferers in the Hospital of Consolazione at Rome.

He died on the octave-day of Corpus Christi, 1591, at the age of twenty-three years. Benedict XIII declared him the patron of young people.
