This testimony is highly valued by first-day writers, and is often and prominently set forth in their publications. Sir Wm. Domville, whose elaborate treatise on the Sabbath has been several times quoted, states the following important fact relative to this quotation:— “I have carefully searched through all the extant works of Irenæus and can with certainty state that no such passage, or any one at all resembling it, is there to be found. The edition I consulted was that by Massuet (Paris, 1710); but to assure myself still further, I have since looked to the editions by Erasmus (Paris, 1563), and Grabe (Oxford, 1702), and in neither do I find the passage in question.”[561] It is a remarkable fact that those who quote this as the language of Irenæus, if they give any reference, cite their readers to Dwight’s Theology instead of referring them to the place in the works of Irenæus where it is to be found. It was Dr. Dwight who first enriched the theological world with this invaluable quotation. Where, then, did Dwight obtain this testimony which has so many times been given as that of Irenæus? On this point Domville remarks:— “He had the misfortune to be afflicted with a disease in his eyes from the early age of twenty-three, a calamity (says his biographer) by which he was deprived of the capacity for reading and study.... The knowledge which he gained from books after the period above mentioned [by which the editor must mean his age of twenty-three] was almost exclusively at second hand, by the aid of others.”[562] Domville states another fact which gives us unquestionably the origin of this quotation:— “But although not to be found in Irenæus, there are in the writings ascribed to another father, namely, in the interpolated epistle of Ignatius to the Magnesians, and in one of its interpolated passages, expressions so clearly resembling those of Dr. Dwight’s quotation as to leave no doubt of the source from which he quoted.”[563] Such, then, is the end of this famous testimony of Irenæus, who had it from Polycarp, who had it from the apostles! It was furnished the world by a man whose eyesight was impaired; who in consequence of this infirmity took at second hand an interpolated passage from an epistle falsely ascribed to Ignatius, and published it to the world as the genuine testimony of Irenæus. Loss of eyesight, as we may charitably believe, led Dr. Dwight into the serious error which he has committed; but by the publication of this spurious testimony, which seemed to come in a direct line from the apostles, he has rendered multitudes as incapable of reading aright the fourth commandment, as he, by loss of natural eyesight, was of reading Irenæus for himself. This case admirably illustrates tradition as a religious guide; it is the blind leading the blind until both fall into the ditch.
