With regard to the manner in which Tertullian performed the work he had undertaken, Hilgenfeld remarks: "As Tertullian, in going through the Marcionitish Gospel, has only the object of refutation in view, he very rarely states explicitly what is missing in it; and as, on the one hand, we can only venture to conclude from the silence of Tertullian that a passage is wanting, when it is altogether inexplicable that he should not have made use of it for the purpose of refutation; so, on the other, we must also know how Marcion used and interpreted the Gospel, and should never lose sight of Tertullian's refutation and defence."(3) Hahn substantially expresses the same opinions. He {95} says: "Inasmuch as Tertullian goes through the Mar-cionitish text with the view of refuting the heretic out of that which he accepts, and not of critically pointing out all variations, falsifications, and passages rejected, he frequently quotes the falsified or altered Marcionitish text without expressly mentioning the variations.(1)... Yet he cannot refrain--although this was not his object--occasionally, from noticing amongst other things any falsifications and omissions which, when he perhaps examined the text of Luke or had a lively recollection of it, struck and too grievously offended him."(2) Volkmar's opinion of the procedure of Epiphanius is still more unfavourable. Contrasting it with that of Tertullian, he characterizes it as "more superficial," and he considers that its only merit is its presenting an independent view of Marcion's Gospel. Further than this, however, he says: "How far we can build upon his statements, whether as regards their completeness or their trustworthiness is not yet made altogether clear."(3) Volk-mar goes on to show how thoroughly Epiphanius intended to do his work, and yet that, although from what he himself leads us to expect, we might hope to find a complete statement of Marcion's sins, the Father himself disappoints such an expectation by his own admission of incompleteness. He complains generally of his free and misleading method of quotation, such, for instance, as his alteration of the text without explanation; alteration of the same passage on different occasions in more than one way; abbreviations, and omissions of parts of quotations; the sudden breaking off of passages just commenced with {96} the indefinite [------], without any indication how much this may include.(1)
