Fr Z has a translation of an article from Il Tempo Motu Proprio next Monday. In addition to Fr Z, this story has already been published by the New Liturgical Movement and Mulier Fortis. So remember - you read it here fourth! In fact, the article says that it will be after next Monday which doesn't really help as much as it might.
But hey! Let's not let that get in the way of another Irresponsible Motu Proprio Speculation Alert. I'm waiting for the brickbat to fly from somewhere in Canada but I think the time difference means that I'm going to get whacked on the back of the head sometime yesterday afternoon.
(Seriously though, Fr Z. makes some important points in his post - as ever, well worth reading.)
