In the late second century, Irenaeus of Lyons, wrote his classic apologetic tome Against Heresies to check, expose and combat the gnostic heresy of the Valentian sect. It is significant to note that the same scripture twisting tactics of the gnostic heretics are still being employed by today's heretics. Said Irenaeus, heretics strive:
"as they do, to adapt the good words of revelation to their own wicked inventions. And it is not only from the writings of the evangelists and the apostles that they endeavour to derive proofs for their opinions by means of perverse interpretations and deceitful expositions: they deal in the same way with the law and the prophets, which contain many parables and allegories that can frequently be drawn into various senses, according to the kind of exegesis to which they are subjected. And others of them, with great craftiness, adapted such parts of Scripture to their own figments, lead away captive from the truth those who do not retain a steadfast faith in one God, the Father Almighty, and in one Lord Jesus Christ, the Son of God.
