The Greek noun “euangelistes”

Limited to Acts 21:8; Eph. 4:11; 2 Tim. 4:5, the Greek noun “euangelistes” meant “evangelist” or “preacher of the gospel.”

Luke said Philip was an “evangelist” (Acts 21:8).  Timothy was to “preach the gospel” (2 Tim. 4:5).  Evangelists have a work which has been specifically sanctioned by God (Eph. 4:11).
