An evangelist is a specific office that is different from pastors & teachers.
Q: According to Protestantism, how does one know if they have been called to be an evangelist?
“He who descended is Himself also He who ascended far above all the heavens, so that He might fill all things.) And He gave some as apostles, and some as prophets, and some as evangelists, and some as pastors and teachers, for the equipping of the saints for the work of service, to the building up of the body of Christ;” Ephesians 4:10-12
