Saint Andrew Avellino (1521-1608) was an Italian lawyer, writer, theologian, Catholic priest, and religious leader of the Theatine order. Recognized for his eloquent preaching, care for the sick, and extensive correspondence and other writings, he was canonized as a saint in 1712 by Pope Clement XI.

Born in Castronuovo, Sicily, and named Lancelotto, he went to elementary school in his hometown before going on to Venice to study philosophy and humanities. He continued his education in Naples, focusing on ecclesiastical and civil law and receiving a doctorate degree in law. He was ordained as a priest at the age of 26.

Avellino worked for a time as a lawyer at an ecclesiastical court in Naples. While arguing a case one day, he lied and felt such remorse that he quit his work to focus on spirituality. After being commissioned in 1556 to reform a local convent, he was attacked by those who opposed the reforms, and he went to recuperate at a monastery of Theatines, an order of clerics founded in 1524 that focused on reforming Catholic morality. While there, he entered the order at the age of 35 and took the name of Andrew, becoming a leader of the movement and helping to form additional Theatine monasteries in Milan, Piacenza, and elsewhere.

Avellino’s religious zeal and eloquent preaching attracted many disciples and new adherents to the Catholic Church, and his many letters and other theological works were published over several volumes beginning in 1731. On November 10, 1608, he died of a stroke while celebrating a mass, and his remains are located at the Church of St. Paul in Naples. He is a patron saint of Naples and Sicily and is often invoked against sudden death.

Saint Andrew Avellino Catholic Academy is located at 35-50 158th Street in Flushing. The school first opened on September 25, 1925, however, the parish church was founded in 1914. When selecting a patron saint for the parish, the bishop at the time was concerned about the number of priests who had suffered heart attacks and thus chose Saint Andrew Avellino.
