hm. I *think* that sound like a thought-terminating cliches; which mean he is under mind control and whatever you say will only make it worse. (correct me if i am wrong).
I think the best approach is to wait a day, and then tell him 'Look, the other day when we talked, you said i was not being humble. I have thought a lot about it, and i would like to talk about about what being humble mean so we wont end up in that situation'.
Then make him agree that being humble mean you must be able to get critisism, that you must not submit to dogma, that you must react on the message, not the messenger, that you can be wrong. Tell him you feel now you were not being humble when you were in the truth, because you was not really examining the bible in a humble spirit, ie. accepting you might be wrong and might need to be corrected....
