Although able critics have for a century sought to edit the Greek Testament on documentary evidence of Greek manuscripts, ancient versions, and early citations, none as yet have succeeded in commanding more than partial confidence. Hence it has been a necessity for any careful and conscientious scholar who would really know the sources to compare several of these editions, and search into the grounds on which their differences depend, so as to have anything like a correct and enlarged view of the text, and to judge fairly of the claims of conflicting readings.... Mature spiritual judgment, with continual dependence on the Lord, is just as essential as a sound and thorough familiarity with the ancient witnesses of all kinds.
Lachmann published a manual edition of the New Testament professedly based on Bentley’s idea of exhibiting the text as read in the fourth century... at one fell swoop sentenced the mass of the surviving witnesses to an ignominious death, and presented us with a text formed on absolute principles of singular narrowness....14 The neglect of internal evidence is a fatal objection. But the grand fallacy involved is that a manuscript of the fourth or fifth century must give better readings than one of the seventh or eighth. Now this is in no way certain. There is a presumption in favor of the more ancient manuscript, because each successive transcription tends to introduce new errors in addition to those it repeats. On the other hand, a copy of the ninth century may have been made from one older than any now extant, and certainly some old documents are more corrupt than many of the more recent witnesses. Every ingenuous scholar must own, to say the least, that the oldest manuscripts have some bad readings, and that the modern manuscripts have some that are good.15 Hence the distinction is not between the united evidence of the most ancient documents (Manuscripts, Versions, Fathers), and the common herd of those more recent; for rarely, if ever, is there such unanimous ancient testimony without considerable support from witnesses of a later day. The truth is that almost always, where the old documents really agree, there is large confirmation elsewhere, and where the ancients differ, so do the moderns. It is quite unfounded, therefore, to treat it as a question pure and simple between old and new. Nor is it the important point of research what particular readings existed in the days of Jerome. For notoriously errors of various kinds had then crept into both Greek and Latin copies, and no antiquity can sanctify an error. The true question is: using every available means to form a judgment, was the primitive text? It is often forgotten that our oldest documents are but copies. Several centuries elapsed between the original issue of the New Testament Scriptures and any manuscripts now existing. All, therefore, are on the ground of copyists differing only in degree. It is not, then, a comparison between a single eyewitness and many hearsay reporters, unless we have the original autographs. And, in fact, we know that an historian’s account, three centuries after alleged facts, may be, and often is, corrected, five hundred or a thousand years after, by recurrence to sources more trustworthy, or by a more patient, comprehensive, and skillful sifting of neglected evidence.
My own conviction is that in certain cases, especially in single words, the most ancient copy that exists may be corrected by another generally inferior, not only in age, but in almost every respect besides, and that internal evidence ought to be used, in dependence upon the Spirit of God,16 where the external authorities are conflicting.
