Today’s saint is inspired by the letter “L.” He also happens to be one of the earliest saints of the Church, and one of the most important, Saint Luke:
Luke the Evangelist (Ancient Greek: Λουκᾶς, Loukás) is one of the Four Evangelists—the four authors of canonical Gospels of Jesus Christ. Luke was a native of the Hellenistic city of Antioch in Syria. The early church fathers ascribed to him authorship of both the Gospel according to Luke and the book of Acts of the Apostles, which originally formed a single literary work, referred to as Luke-Acts. Prominent figures in early Christianity such as Jerome and Eusebius later reaffirmed his authorship, although within scholarly circles, both secular and religious, discussions have taken place due to the lack of evidence as to the identity of the author of the works.
The New Testament mentions Luke briefly a few times, and the Pauline epistle to the Colossians refers to him as a doctor; thus he is thought to have been both a physician and a disciple of Paul. Christians since the faith’s early years have regarded him as a saint. He is believed to have died a martyr, although accounts of the events do vary.
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.
