For those who insist that Benedict XVI was never a modernist, it seems useful to bring to their attention an article that was recently published by the progressivist weekly The Tablet (September 12, 2009, p. 30). Indeed, as the photocopy below reports, Prof. Michael Schmaus - to whom Fr. Ratzinger submitted his post-doctoral thesis - rejected it as being "dangerously modernist."
It is also worthwhile keeping in mind that Card. Joseph Ratzinger affirmed many times that he never changed the convictions he had when he was young.
