It is a unknown bystander who praises Mary.
So if the same woman praised Judas Iscariot, do we claim the Bible praises Judas Iscariot?
It is who is talking that is important, not something that is said by someone of 'unknown stature'.
So if Judas Iscariot said something in the Gospel, then we should heed it? Obviously not.
The woman speaking is not known who she is. That makes the passage 'dubious'.
The words of Jesus are eternal, which is why we must heed them.
I consider that Jesus is re-directing this woman with his response.
Clearly, person who is addressed by an angel (Gabriel) to be the mother of God is a very special person. In my opinion, that is the important scripture.
Yes, so this is exactly the pattern of veneration of saints today. It is not a requirement, but a spontaneous expression of faith in life eternal granted to Catholic and Orthodox Christians by Jesus Christ. It is also significant that Jesus augments and corrects the manner of veneration, but does not stop the veneration itself.
We can speculate whether He would have stopped a spontaneous veneration of Judas, but the Holy Scripture does not record such an incident, but instead records this one, for our instruction. Let us learn.
