If this document is written in the same language that has been coming out of the Vatican of late, it will not be long before "loopholes" and exceptions will be found. And of course many bishops will just file this document in the circular file with all the others.
Funny thing... when I read these Vatican documents, in light of Tradition, they seem thoroughly orthodox. Then I run into some raving modernist nutter, who reads them in a spirit of looking for excuses, and she manages to twist them into all manner of heretical distortions. They're written in a bureaucratic gobbledygook style that gives too much room for misinterpretation, to those inclined to misinterpret.
