'Evangelist' in the Bible

On the next day we left and came to Caesarea, and we went to the house of Philip the evangelist, who was one of the seven [deacons], and stayed with him.

But as for you, be clear-headed in every situation [stay calm and cool and steady], endure every hardship [without flinching], do the work of an evangelist, fulfill [the duties of] your ministry.
