Fr Weinandy's letter is simple and temperate yet cuts far deeper than the filial correction. Here we get to the heart of the matter; the Pope is vocally hostile to doctrine itself and sets Christian doctrine against Christian practice when it is convenient.

But however temperate his letter is, the need for his resignation was set when he noted that some bishops nominated by Francis are less than faithful. Even without naming names, if one works for a bishops' conference that puts one's employers in a tight spot, unless bishops are to start anaethmatizing other bishops.  Maybe that is what we need, but it won't happen until things get much worse.
