Very good. It's about time a highly respected cardinal indirectly casts a doubt about the supposedly "dogmatic" and "infallible" VC II; specifically this:
The Church regards with esteem also the Moslems. They adore the one God, living and subsisting in Himself; merciful and all- powerful, the Creator of heaven and earth,(5) who has spoken to men; they take pains to submit wholeheartedly to even His inscrutable decrees, just as Abraham, with whom the faith of Islam takes pleasure in linking itself, submitted to God. Nostra Aetate
and this:
But the plan of salvation also includes those who acknowledge the Creator. In the first place amongst these there are the Mohamedans, who, professing to hold the faith of Abraham, along with us adore the one and merciful God, who on the last day will judge mankind. Lumen Gentium
I agree. Unfortunately he makes no mention of Vatican II. And he needs to.
