Irenaeus
In the context of describing the erroneous beliefs and practices of heretics, Irenaeus disapprovingly mentions that they venerate images "after the same manner of the Gentiles". The way in which they venerate images is no different from what Roman Catholics do. No Roman Catholic would disapprove of venerating an image of Jesus this way, but Irenaeus does disapprove of it:
"Others of them employ outward marks, branding their disciples inside the lobe of the right ear. From among these also arose Marcellina, who came to Rome under the episcopate of Anicetus, and, holding these doctrines, she led multitudes astray. They style themselves Gnostics. They also possess images, some of them painted, and others formed from different kinds of material; while they maintain that a likeness of Christ was made by Pilate at that time when Jesus lived among them. They crown these images, and set them up along with the images of the philosophers of the world that is to say, with the images of Pythagoras, and Plato, and Aristotle, and the rest. They have also other modes of honouring these images, after the same manner of the Gentiles." (Against Heresies, 1:25:6)
"These men [heretics], moreover, practise magic; and use images, incantations, invocations, and every other kind of curious art." (Against Heresies, 1:24:5)
