What was Luke's profession prior to becoming a follower of Christ and a missionary?

Answer: Physician (doctor)

Explanation: According to sacred tradition, St. Luke one was not one of the twelve first apostles of Christ but belonged to the so-called 70 minor apostles. He was a doctor by profession before he became a follower of Christ, therefore a Christian, and it is considered that he was a Gentile before that. The fact that St. Luke was a physician before he became a Christian is found in the letters of the Apostle Paul. Of course, with the acceptance of Christianity and following the path of Christ, he continued to be a physician except that he was a Christian, and he also used it on a missionary path. He wrote one of the four Gospels of the New Testament, the third in a row, and is also thought to have known the Apostle Paul and spread and preached the teaching of Christ with him, thus missionary. He is also thought to have written Acts of the Apostles. He was also an icon painter, according to tradition, and painted the first Christian icon ever to paint the Virgin Mary.
