Matthew 24:11

And many false prophets shall rise
Out of, from among the churches of Christ; at least under the name of Christians; for false teachers are here meant, men of heretical principles, pretending to a spirit of prophecy, and to new revelations, and a better understanding of the Scriptures; such as Simon Magus, Ebion, and Cerinthus, who denied the proper deity, and real humanity of Christ; Carpocrates, and the Gnostics his followers, the Nicolaitans, Hymcneus, Philetus, and others:

and shall deceive many:
as they all of them had their followers, and large numbers of them, whose faith was subverted by them; and who followed their pernicious ways, being imposed upon and seduced by their fair words, specious pretences, and licentious practices.
