You yourself must agree that St. Paul is speaking in hyperbole since, in quoting Isaiah, he makes no exception -- not even for the Sacred Human Nature of Christ. Since he did not make exception for Our Lord's sinless human nature, the statement cannot be taken literally. The reason that St. Paul is quoting Old Testament references here (which of course pre-dated both Christ and His mother) was to stir the consciences of his fellow Jews. He wants to show them that they are no superior to the Gentiles by reminding them of the repeated Old Testament apostacies of the Jewish people.
You really do a disservice to your own religion by playing these games of ripping Scriptural passages from their contexts and offering them up as proof of some separate theological point. This silliness demonstrates intellectual laziness and a simplistic approach to things of God.
Furthermore, sir, your posts suggest that your ignorance of Catholic doctrine and practice is of monumental proportions -- certainly greater than that of even the typical FR Catholic baiter. Before uttering any more outrageous misstatements of our faith, please consult a catechism to ensure that your sure-to-be-erroneous post is at least minimally based on actual Catholic teaching.
I was addressing certain obvious errors that stand against God's Holy Word, the only irrefutable standard that we all have. - How those errors may, or may not relate to such doctrines is not for the outsider to address, since erroneous doctrine affects only the individual(s) holding said doctrine.
