(2.) It is true that some doctrines are affected by the variant readings in Sinaiticus and other mss. If not the doctrine itself, then at least the degree of certainty with which it can be held or proved, or the place it should hold in the theological system, comes under question. But the reality is that false doctrines are only proved by bringing some foreign presupposition to the text, and this is more likely to the degree that an individual regards the Bible as a collection of human writings and rejects its divine inspiration and infallibility. (3.) The liberal use which is being made of ms. evidence and variant readings with respect to doctrine and history demonstrates that text-critical work is not neutral. The old idea that text-critical theories do not affect the canon of Scripture or the substance of the faith cannot be upheld. The acceptance of certain text-critical theories go hand hand with specific attitudes to history and doctrine which have serious consequences for the canon of Scripture and the substance of the faith. The idea of an "eclectic" method, in particular, presupposes a developmental theory of text and canon which immediately conflicts with traditional conservative views. (4.) The degree to which Sinaiticus is accepted as being a text-critical document instead of an ecclesiastical text in current use should affect the value one places in its variant readings. The idea of a neutral text (which still continues to predominate modern critical texts even though the theory itself has been replaced) should be well and truly rejected. (5.) The whole issue demonstrates that one must presuppose not only the inspiration and infallibility of Scripture, but the integrity of its preservation, in order to be able to stand upon the Word of God and declare, Thus saith the Lord. Much of the criticial methodology has proven destructive to conservative Christianity in general and to reformed theology in particular. As we are bound to accept the Bible on the basis of its own witness, we are shut up to the conclusion that it has been preserved pure and entire, and is readily accessible as a final court of appeal (WCF 1.8). This means there is an historical and doctrinal presupposition which strongly favours the ecclesiastical text on which the reformers and their successors based the Protestant witness and tradition.
