This website (link) catalogues 101 alleged heresies of Benedict XVI. Now, obviously, the RCC does not teach that popes are perfect. I wonder, though, whether any supporter of Ben16 has taken the time to debunk the list above, which - at first glance - appears to be documented with evidence from various sources.
The list is something of a catch 22.
-If the list is true and accurate, Ben16 is more of a liberal protestant than one might think.
-If the list is accurate as the left column (Ben16's views) but inaccurate as to the right column (RCC dogma) and if Ben16's views are the view of the RCC, then all sorts of new issues are raised.
-If the list is accurate as to the right column but not the left column, and if Ben16's views are the view of the RCC, then a different set of new issues are raised.
In any event, regardless of the answers, it would handy to have a continuationalist (as opposed to a sedavacantist) RCer "debunk" or confirm the list. I don't think it's been done, but I admit my fallibility.
