(a privative, and λογος), in Church History, a sect of ancient heretics, towards the close of the second century, so called because they denied that Jesus Christ was the Logos. They likewise denied the continuance of the charismata, or special spiritual gifts, in the Christian church, and accordingly rejected the prophetical portions of the New Testament, besides the Gospel of John. They were particularly opposed to the Montanists; but our information regarding them is very scanty. They are first mentioned by Epiphanius.
