Sorry folks, but I am not at all impressed with the overall result of the discussion on the most recent thread on 'What is evangelical textual criticism'. I think it should be possible to come up with something more constructive. So bear with me.
By means of introduction, evangelicals practising textual criticism (are/should be) aware of human imperfection in history ('many things did go wrong') as in our study of textual history ('we may get things wrong'). This is not a unique point for textual criticism, or even of evangelical scholarship in general, but it is in my view a sine qua non.
I think there are three basic assumptions that characterise evangelical textual criticism (each with their own modifications and refinements, but we are not going to bother with these).
1) There is an 'original text' to aim for in New Testament textual criticism.
2) There is the theological conviction that the preservation of the New Testament is sufficiently reliable.
3) The canon of the New Testament is (in one way or the other) a real and given entity.
Each of these points should be properly expanded and clarified in what they affirm and deny, and can probably be refined in their wording, and perhaps there are even other foundational notions. But I think these three taken together constitute a neat distinctive for evangelical textual criticism.
