So eating a vegetable because someone says it’s good for you is the same as heeding what God says about His Word. Gotcha! If you have an allergy to that vegetable, it is still good for you? Some Catholics must have an allergy to God’s Word.
Now you're just trying to mangle the analogy.
You already admitted it "might" (weasel wording) be valid if it weren't God's Word under consideration. Of course you allude to NOTHING else that might make it invalid EXCEPT that it's God's Word, so that must be your reasoning.
