An apostle, from Classical Greek ἀπόστολος (apóstolos), meaning "one who is sent away", is a messenger and ambassador. The purpose of such "sending away" is to convey messages, and thus "" is a common alternative translation. The term may be used metaphorically in various contexts, but is mostly found used specifically for early associates of the founder of a religion, who were important in spreading his teachings. The word in this sense derives from New Testament Greek and was used for the original Twelve Apostles of Jesus, as well as a wider group of Early Christian figures including Paul. Some other religions use the term for comparable figures in their history. The adjective "apostolic" is claimed as a continuing characteristic by many Christian churches, and so used far more widely, as in the Apostolic See as the official name for the Roman Catholic Papacy.
