Denis Lamoreaux liberal, sure. Peter Enns, maybe.
But
N.T. Wright?
Unconventional he may be, and disagreed with by many, but calling him a liberal is just about as credible as calling Stephen Gould a Christian or Kevin Rudd a Chinese.
A five-minute Google search reveals that the man is deeply interested in the question of how the Bible is authoritative:
[FONT="]So, secondly within the first half of this lecture, I want to suggest that scripture’s own view of authority focuses on the authority of God himself. (I recall a well-known lecturer once insisting that ‘there can be no authority other than scripture’, and thumping the tub so completely that I wanted to ask ‘but what about God?’

If we think for a moment what we are actually saying when we use the phrase ‘authority of scripture’, we must surely acknowledge that this is a shorthand way of saying that, though authority belongs to God, God has somehow invested this authority in scripture. And that is a complex claim. It is not straightforward. When people use the phrase ‘authority of scripture’ they very often do not realize this. Worse, they often treat the word ‘authority’ as the absolute, the fixed point, and make the word ‘scripture’ the thing which is moving around trying to find a home against it. In other words, they think they know what authority is and then they say that scripture is that thing.[/FONT]
[FONT="]I want to suggest that we should try it the other way around. Supposing we said that we know what scripture is (we have it here, after all), and that we should try and discover what authority might be in the light of that. Granted that this is the book that we actually have, and that we want to find out what its ‘authority’ might mean, we need perhaps to forswear our too-ready ideas about ‘authority’ and let them be remolded in the light of scripture itself—not just in the light of the biblical
statements about authority but in the light of the whole Bible, or the whole New Testament, itself. What are we saying about the concept of ‘authority’ itself if we assert that this book—not the book we are so good at turning this book into—is ‘authoritative’?[/FONT]
[FONT="][/FONT]
[FONT="]Beginning, though, with explicit scriptural evidence about authority itself, we find soon enough—this is obvious but is often ignored—that all authority does indeed belong to God.
‘In the beginning, God created the heavens and the earth’. God says this, God says that, and it is done. Now if that is not authoritative, I don’t know what is. God calls Abraham; he speaks authoritatively. God exercises authority in great dynamic events (in Exodus, the Exile and Return). In the New Testament, we discover that authority is ultimately invested in Christ: ‘all authority has been given to me in heaven and on earth’. Then, perhaps to our surprise, authority is invested in the apostles: Paul wrote whole letters in order to make this point crystal clear (in a manner of speaking). This authority, we discover, has to do with the Holy Spirit. And the whole church is then, and thereby, given authority to work within God’s world as his accredited agent(s). From an exceedingly quick survey, we are forced to say: authority, according to the Bible itself, is vested in God himself, Father, Son and Spirit.

How Can The Bible Be Authoritative? by N.T. Wright[FONT="][/FONT] (emphasis added)
Wow! That feels a little bit too conservative for me! Who knows, you might have actually liked the guy. Newsflash mark: not everybody who disagrees with you is a liberal heretic. Evangelicalism doesn't have popes, remember?
