“Where diversity of doctrine is found, there, then, must be corruption both of the Scriptures and the explanations of them. . . . One man perverts the Scriptures with his hand, another their meaning by his exposition.  For although Valentinus seems to use the entire volume [of Scripture], he has nonetheless laid violent hands on the truth only with a more cunning mind and skill than Marcion.  Marcion expressly and openly used the knife, not the pen, since he made such an excision of the Scriptures as suited his own subject-matter.  Valentinus, however, abstained from such excision, because he did not invent Scriptures to square with his own subject-matter, but adapted his matter to the Scriptures; and yet he took away more, and added more, by removing the proper meaning of every particular word, and adding fantastic arrangements of things which have no real existence.”
