Saint Apostle Luke 3d printable model relief for cnc Luke the Evangelist[a] is 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 of Luke and the Acts of the Apostles. Prominent figures in early Christianity such as Jerome and Eusebius later reaffirmed his authorship, although a lack of conclusive evidence as to the identity of the author of the works has led to discussion in scholarly circles, both secular and religious.

The New Testament mentions Luke briefly a few times, and the Epistle to the Colossians[3] refers to him as a physician (from Greek for 'one who heals'); thus he is thought to have been both a physician and a disciple of Paul.
