Today the church remembers and celebrates as a Feast Day St. Luke the Evangelist, physician, and traveling companion of the Apostle Paul. Saint Luke, a companion and fellow-worker of Paul, was a Gentile by birth and a physician by vocation (see Col. 4:14). We first meet St. Luke during St. Paul’s second missionary journey. His witness to our Lord Jesus Christ is found in his two books, the Acts of the Apostles and the Third Gospel.
One commentator writes: “In St. Luke’s Gospel our Savior is pictured as the merciful Physician of bodily and spiritual ills. It has, therefore, been called ‘the Gospel of mercy and love.’
