 Some Christian traditions consider evangelists to be in a leadership position; they may be found preaching to large meetings or in governance roles.Christian groups who encourage evangelism are sometimes known as evangelistic or "evangelist".The word "evangelist" comes from the Koine Greek word (transliterated as "euangelion") via Latinised "evangelium" as used in the canonical titles of the Four Gospels, authored by (or attributed to) Matthew, Mark, Luke, and John (also known as the Four Evangelists).
