He was born in northern Spain, in the town of Saint Facundo. He was a brilliant and attractive young boy, educated in the household of a bishop. He became one of the Hermits of Saint Augustine. His devotion to the Blessed Sacrament was so great that he spent every night, from the hour of Matins at midnight, to the hour of Mass in the morning, in adoration of Our Lord in the Blessed Eucharist. He was often privileged in the saying of Mass to see Our Lord visibly in the Blessed Eucharist. Saint John of Saint Facundo is the patron saint of Salamanca in Spain. He died when he was sixty years old.
