Liberal aand revisionist theologians reject the idea of the Bible as the written Word of God. This is a given in modern theological thinking. The Bible represents the religious "God-consciousness" of people down the centuries, but it is not God speaking through their ideas in a real personal revelation.
There is a strange irony here, though - since the same theologians who deny the idea of God putting a book together through inspiring human prophets and apostles, write their own books and get them published. They have ideas, put them in writing, get them published, want them discussed and heeded. Why can't God do the same?
