St. James the Less is one of the Twelve apostles chosen by Jesus. He is also called “the Minor”, “the Little”, “the Lesser”, or “the Younger”, according to translation. He is not to be confused with James the Great (also called “James the Elder”). He is identified by some as James, son of Alphaeus and as James, brother of Jesus, thought of by Jerome and others as really the cousin of Jesus.
St. Philip the Apostle was also chosen by Jesus. Christian tradition describes Philip as the apostle who preached in Greece, Syria, and Phrygia.
In the Roman Rite, the feast day of Philip, along with that of James the Less, was traditionally observed on 1 May, the anniversary of the dedication of the church dedicated to them in Rome (now called the Church of the Twelve Apostles). In 1955, their feast day was moved to May 11 to accommodate the Feast of St Joseph the Worker on May 1. A later revision of the calendar moved the feast back to May 3.
