Quick question, if you admired your sponsor for not giving you his opinions and interpretations, why would you admire J&C for selling their opinions and interpretations of the steps and our book? Having your own understanding and experience with our material shouldn't be sacrificed in favor of taking on board that of any false wannabee authorities.
Listen when others tell you what they found to be true for them, but make your own search. What they did, what they came to understand and believe does you not the least bit of good.
