Directly from the Vatican
I read the article you linked. I still see problems. The blessings are not for an individual but for a couple (the way I read it). This sets up the very thing it says to avoid: confusion. Overall it seems to be making a distinction without a difference. Further, I think we all know there are more than a few priests who will take this way beyond its intent. Surely the Pope knows this, too, which makes the statement reckless.
