We had a long, somewhat productive but eventually not so productive discussion about this a while back where people dug up some of the history of calling the canon “God’s Word” or the “Word of God.” It’s a tradition that predates English.
The texts that make up the Christian canon were not “the Bible” when they were written, so of course references to God’s word in Scripture mean something other than “the Bible” and an oblique reference to Scripture that existed at the time as “God-breathed” is not a full-fledged doctrine of inspiration of the canon. Formal theology around the idea that the Bible is the inspired word of God came into Christian tradition much later.
