"The four cardinals haven't actually raised any objections to Amoris Laetitia per se."

Really, Marty?  In your previous posts you defended this gang of four as the only thing standing between the RCC and false teaching.  In their letter, Burke and his henchmen said AL cause "grave confusion."  

Also, Hans Kung was a single theologian.  He wasn't a group of sour faced Cardinals upset that he didn't win the last conclave.
