Saint Andrew Avellino († 1608) was an Italian Theatine priest who led a life busy in preaching, hearing confessions, visiting the sick, and writing. Born at Castronuovo, a small town in the province of Potenza Basilicata, his baptismal name was Lancelotto, which out of love for the Cross he changed into Andrew when he entered the Order of Theatines. He was so successful in converting sinners and heretics by his prudence in the direction of souls and by his eloquent preaching, that numerous disciples thronged around him, eager to be under his spiritual guidance. He is a patron of Naples, Sicily, and invoked against sudden death.
