Saint Luke the Evangelist was one of the Four Evangelists—the four traditionally ascribed authors of the canonical Gospels. The early church fathers ascribed to him authorship of both the Gospel according to Luke and the book of Acts of the Apostles, which would mean Luke contributed over a quarter of the text of the New Testament, more than any other author. The Roman Catholic Church and other major denominations venerate him as Saint Luke the Evangelist and as a patron saint of artists, physicians, surgeons, students and butchers; his feast day takes place on 18 October.
