Angel (malach) is a Hebrew word meaning messenger. It means the same in Arabic and Greek. The tradition of angels begins with an encounter of an angel as a messenger. Augustine sees the word angel as a role rather than a nature. An angel could be a human being. There is some confusion in Judaism, Christianity, and Islam, as to where the voices of angels come from and ambivalence about what angels actually are. If there is so much debate about the existence of angels why is it that so many people claim to have had an encounter with an angel?
