Nope. The same word, μενουνγε, is used also in Romans 9:20 and Romans 10:18; one can argue about the former, but in the latter the meaning is clearly "yes, rather" (KJV translates "yes, verily"). Note that Christ's version of the veneration is still veneration: "blessed are they who hear the word of God, and keep it", just applied more broadly. Negation would be "no, not blessed at all".

Are you looking for truth or desperately trying to inject meaning? The word is used only three times in the New Testament. Each time it is used to correct a previous statement. Let's look at your examples.

In Romans 9 they were questioning why God made men like Pharaoh and then finds fault in them. Paul is correcting their statement.

Again in Romans 10:18 the statement had been made that Israel really hadn't heard the word. Paul corrects them by saying "oh yes they did".

So to in Luke 11:28 Jesus is correcting a prior statement.

I understand that you want to defend the teachings of the Catholic Church but it's clear that in Luke 11:28 Jesus is correcting a statement not verifying it.
