Well, my friends, it has been released. Although I haven't read a translation of the document itself, the Vatican website does have a translation of the letter that accompanies it. There is one sentence I would like to highlight.
"I would like to draw attention to the fact that this Missal was never juridically abrogated and, consequently, in principle, was always permitted."
From the mouth (or should I say pen) of the Holy Father himself. The old Mass was never abrogated and, well, I guess I can't put it better myself. My initial reaction to this document is very good, however, I'm waiting on an official translation to read because, as I have said, I only have a translation of the accompanying letter.
