A messenger from God, of a nature different from mankind. Angels can be seen and speak, but they can also appear and vanish at will. There was much angelic activity associated with Jesus: The announcements to Zechariah, Mary, and the shepherds; angelic ministry to Jesus in the wilderness and in the garden of Gethsemane; and the announcements to the women and the disciples at the empty tomb and the Mount of Olives. Evil spirits were sometimes called "Satan's angels," suggesting that some angels chose to disobey God and fell from his grace.
