Selected Mass Reading

Responsorial Psalm — Psalm 37:3-4, 18 and 23, 27 and 29

Trust in the Lord, and do good, and dwell in the land, and thou shalt be fed with its riches. Delight in the Lord, and he will give thee the requests of thy heart. The Lord knoweth the days of the undefiled; and their inheritance shall be for ever. With the Lord shall the steps of a man be directed, and he shall like well his way. Decline from evil and do good, and dwell for ever and ever. But the just shall inherit the land, and shall dwell therein for evermore.

Saints Memorialized Today

Leo I
Leo I Pope, Bishop of Rome, Theologian, Writer, Doctor of the Church 390–461

Saint Leo I, born around 391, was a Roman aristocrat, likely a native of Tuscany. As a deacon he was already trusted for his wisdom and steadiness, and in 440 he was unanimously chosen as Bishop of Rome, guiding the Church through years of doctrinal conflict and social upheaval. Leo defended the faith with clarity and courage, confronting errors that threatened Christian unity and strengthening pastoral discipline across Italy, Gaul, Spain, and North Africa. In a Rome strained by famine, refugees, and poverty, he urged believers to join fasting with generous almsgiving, making charity a hallmark of true repentance. He is especially venerated as a Doctor of the Church for the Tome of Leo, which helped the Council of Chalcedon proclaim that Christ is one Person in two natures, divine and human, without confusion or division. Tradition also remembers his meeting with Attila the Hun in 452, when his presence helped turn the invader back from Italy. He is patron of places including Cairano and Sperlonga. His feast day is November 10.

Feast Days

Andrew Avellino
Andrew Avellino Catholic priest, Theatine 1521–1608

Saint Andrew Avellino was born in 1521 at Castronuovo in Basilicata (today Castronuovo di Sant’Andrea), Italy, and was baptized Lancelotto. Gifted in mind and presence, he studied in Venice and later in Naples, where he earned a doctorate in civil and canon law and was ordained a priest at twenty-six. Serving for a time in the ecclesiastical courts, he was soon entrusted with reforming a scandal-ridden convent. His courageous work restored discipline but provoked violent opposition, and he was badly wounded in an assault. During his recovery among the Theatines, he resolved to belong wholly to God and entered their young order, taking the name Andrew. As master of novices, superior, and founder of new Theatine houses, he labored for the renewal of clergy and people through preaching, confession, spiritual direction, and care for the sick, supporting the reforms of the Council of Trent. He died on November 10, 1608, struck by apoplexy as he began Mass, and is invoked especially against sudden death and for those suffering stroke. He is patron of Naples and Sicily, and also of Badolato, Castronuovo di Sant’Andrea, and Monasterace. His feast day is November 10.

Saint Ninfa
Saint Ninfa Virgin, Martyr 300–316

Saint Ninfa, born in Palermo around the year 300, is honored as one of the four patron saints of Palermo, Sicily. Though few details of her life have come down to us, her enduring place in the faith of her city speaks of a witness that generations have cherished. Living in the early centuries of the Church, she is remembered with special devotion by the people of Palermo, who continue to call upon her intercession under the title Santa Ninfa. Saint Ninfa died in 316, and her memory remains woven into the spiritual identity of her homeland. Each year her feast is kept on November 10, inviting the faithful to renew their trust in God and to seek the prayers of this beloved patroness.
