In the Greek world a person who acted as an official representative or emissary would be called a “herald” (κῆρυξ, kēryx; 1 Tim 2:7; 2 Tim 1:11), “ambassador” (πρεσβευτής, presbeutēs; cf. Eph 6:20; 2 Cor 5:20), or “messenger” (ἄγγελος, angelos; cf. Gal 4:14), but not an “apostle” (ἀπόστολος, apostolos).
