or gospel of St. Luke, a canonical book of the New Testament.

Some think it was properly St. Paul's gospel, and that when that apostle speaks of his gospel, he means what is called St. Luke's. Irenaeus says, that St. Luke digested into writing what St. Paul preached to the Gentiles; and Gregory Nazianzen tells us, that St. Luke wrote with the assistance of St. Paul.

St. Luke the evangelist's day, a festival in the Christian church, observed on the 18th of October.
