Apostle Philip is one of the Twelve Apostles, he was from Bethsaida of Galilee and was a compatriot of Andrew and Peter. He was instructed in the teachings of the Law and devoted himself to the study of the prophetic books.
Therefore, when the Lord Jesus called him to the dignity of apostleship, he immediately sought out and found Nathanael and said to him, "We have found Him of Whom Moses in the Law and the Prophets did write, Jesus of Nazareth, the son of Joseph" (John 1.45).
Having preached Jesus the God-man throughout many parts of Asia Minor, and having suffered many things for His Name's sake, he was finally crucified upside down in Hierapolis of Phrygia.
There were actually two Saint Philips in the Orthodox Christian Church history. This particular Saint Philip was one of the Twelve Apostles and he is referred to as Philip the Apostle. He is one of the Apostles who was martyred while preaching about Jesus Christ.
His memory is commemorated by the Greek Orthodox Church on 14 November.
Today is also the name day of Philipos and Philipia.
