There are so many excellent portions of the book, CoC.
I like Ray's point on p.41 (fourth edition) where he asks, "do scriptural examples themselves urge against disclosure of wrongs where these involve those in high places of authority? It does not seem so, since the work of the Hebrew prophets frequently focused on such ones, those prophets making known the ways in which Israel's leaders and men in authority, even high priests, had strayed from God's standards with resulting problems. Jehovah's witnesses have often pointed to such candor and openness as one of the evidences that the Bible is truthful, genuinely God's book."
I also like the ending of chapter 10' where he quotes from an apology given by Herbert Armstrong's Worldwide Church of God, where they mentioned their flawed doctrinal understandings and unscriptural practices. If you read this letter without the background information, it sounds exactly like the sort of apology the WTS could and should have written, but probably never will.
