lit., "a messenger of good" (eu, "well," angelos, "a messenger"), denotes a "preacher of the Gospel," Act 21:8, Eph 4:11, which makes clear the distinctiveness of the function in the churches; 2Ti 4:5. Cp. euangelizo, "to proclaim glad tidings," and euangelion, "good news, gospel." Missionaries are "evangelists," as being essentially preachers of the Gospel.
