Torrance finds crucial hermeneutical implications in such a view of Scripture. The real text of which we are to be concerned with, according to Torrance, is not the letter of Scripture but the humanity of Christ "as the actual objectification of the Word of God for us within our human mode of existence in space and time. It is to this which the Scriptures refer." The "this-worldly reality," the human aspect of hermeneutics is inherent in the genre of Scripture itself. This is best seen in the parables of Jesus. As they relate their humanness to the humanity of Christ, they point to Christ as the real text of Scripture. "He is God's exclusive language to us and He alone must be our language to God." It is a mark of the New Testament authors, according to Torrance, that
Far from obtruding themselves and their own spirituality upon us, the New Testament writers serve the gospel by directing us back to the representative and vicarious humanity of Christ as the creative ground and normative pattern for actualization of every response to God on our part. It is in fact the humanity of Jesus Christ himself which is the real text underlying the New Testament Scriptures; it is his humanity to which they refer and in terms of which they are to be interpreted.

By the way, I have taken this quote from the above bibliographic information; and this is a review copy sent to me by James Stock (of Wipf and Stock), of which I am rereading (currently)---since I failed to do the review after I finished reading it the last time, and thus need to refresh myself in order to do a proper review---anyway, you can purchase this book (and you should) by clicking here.
So, there is a lot in this quote. And I would imagine for the typical Evangelical or Reformed person that what is communicated about Torrance's approach on all of this won't go down too smoothly. But, understand that Torrance's view is not "amening" the higher critical method which seeks to undercut the "authority" and centrality of Scripture as God's Word to humanity. Just the opposite! Torrance (and Barth) are seeking to articulate a doctrine and ontology for scripture that sees it in its rightful dogmatic place relative to Jesus Christ's Self-revelation as God's first and last Word for us. We, in America, especially, are obsessed (still!) with scripture meeting some kind of external and public mode of criteria for verifying whether or not it can be trusted or not (as God's Word). But rest assured, scripture is God's Word not because we say so, but because God has said so through his Self-revelation in Jesus Christ. God's Word, as it finds its groove and grip in its rootedness in God's triune speech to us, has the capacity to contradict all of our thoughts (including verification models for adjudicating whether or not scripture can be trusted), 'all the way down'.
In effect, when we ask whether or not Barth, Torrance & co. believed that the Bible was "errant," we need to ask these questions cognizant that Barth, Torrance & co. were not antagonistic toward scripture (as is the case of most of the critics who are usually, and modernistically, trying to punch holes in scripture); instead they were highly driven by their devotion to the God of scripture's giving. Just bear this in mind.
