Saint John of San Facundo, Confessor

S. Ioannis a S. Facundo Confessoris

WhiteThird Class12 June

Saint John of San Facundo was a Spanish friar of the Order of Saint Augustine in the fifteenth century, a celebrated preacher and peacemaker, renowned for his tender devotion to the Most Holy Eucharist.

Saint John was born in the town of San Facúndo, now called Sahagún, in the kingdom of León in Spain, about the year 1419, and from his birthplace he takes his name. The prayer of his feast addresses God as the author of peace and the lover of charity, who adorned His confessor John with a wonderful grace for reconciling those at variance.

Priest and Augustinian friar

Educated by the Benedictines and ordained a priest, John for a time held several benefices, but his conscience moved him to give them up and to seek a more perfect life. After studies at the University of Salamanca, and following a serious illness during which he resolved to leave the world, he entered the Order of the Hermits of Saint Augustine at Salamanca. There he embraced the religious life with great fervour, holding various offices in his community and giving himself to prayer, penance, and the care of souls.

Preacher and peacemaker

John became a powerful preacher, fearless in proclaiming the truth and in rebuking vice, yet so filled with charity that his words drew sinners to repentance rather than driving them away. The city of Salamanca in his day was torn by bitter feuds among its noble families. By his preaching and his patient labours, John was able to reconcile many of these warring factions and to restore peace to the city, so that he came to be regarded as its peacemaker. He bore opposition and danger for the sake of justice with great calm, trusting wholly in God.

Devotion to the Eucharist and his witness today

Above all, Saint John was marked by an extraordinary devotion to the Holy Eucharist. He offered the Sacrifice of the Mass with such reverence and recollection that he was sometimes seen rapt in prayer at the altar. He died at Salamanca in 1479 and was canonised in 1690. The Church prays on his feast that, by his merits and intercession and being strengthened in the charity of God, we may be separated from Him by no temptations. In Saint John the gifts of the preacher, the peacemaker, and the lover of the Blessed Sacrament were united in one holy life.

The Collect

O God, author of peace and lover of charity, who didst adorn blessed John, Thy Confessor, with a wonderful grace for reconciling those at variance: grant, by his merits and intercession, that, being strengthened in Thy charity, we may be separated from Thee by no temptations. Through our Lord.

Deus, auctor pacis et amátor caritátis, qui beátum Joánnem Confessórem tuum mirífica dissidéntes componéndi grátia decorásti: ejus méritis et intercessióne concéde; ut, in tua caritáte firmáti, nullis a te tentatiónibus separémur. Per Dóminum.
