I'm not involved in the works/faith dispute. As Red Sky said, both aspects are part of the journey- simple. You're the one reading too much into chapter 8, or maybe too little. Kind of sad you're choosing to translate Word to "saying". There wasn't a book floating around in the beginning; a way to think of his word is as consciousness or universal intelligence. God's word is more than a saying.
In chapter 8, at the temple, Jesus is preaching forgiveness, God as the true father, his own divinity, works, faith... all together. He's also illuminating the notion of the Word. The central message Jesus conveys is about his connection to God, that he is the son. His way of thinking is of God, not men. He's sparkling with wisdom. He rebukes the Pharisees from different angles. In each section of dialogue he's saying nearly the same thing within different idioms (much like his teaching as a whole). Chapter 8 is about hearing the Word, reminding us that if we can hear "it", God is in us.
37 "I know that you are Abraham's descendants, but you seek to kill Me because My word has no place in you.
43 "Why do you not understand My speech? Because you are not able to listen to My word.
47 "He who is of God hears God's words; therefore you do not hear, because you are not of God."
Returning to the original post: Christians follow God and Christ, all the Fathers, Mothers , saints, judges, prophets, apostles, preachers, etc. Paul and the theologians are only among the witness's... they're not superior to HIM. Faith has made us whole, not the logic of men.
