Philip the Apostle () was one of the Twelve Apostles of Jesus. Later Christian traditions describe Philip as the apostle who preached in Greece, Syria, and Phrygia. In the Roman Catholic Church, the feast day of Philip, along with that of James the Just, 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). The Eastern Orthodox Church celebrates Philip’s feast day on 14 November. One of the Gnostic codices discovered in the Nag Hammadi library in 1945 bears Philip’s name in its title, on the bottom line.
