The Greek verb apostello means "to send out." The noun form, apostolos, means "one who is sent." The English word apostle is a transliteration, rather than a translation, of the Greek word. The apostles were "sent ones." But they were not mere messengers.The Greek word for "messenger" was angelos, from which we get our word "angel." An apostolos was something more significant than a courier or a herald; apostolos conveyed the idea of an ambassador, a delegate, an official representative.
