Well, not only did they do it, but they are doubling down with a sledgehammer. The Dicastery for the Doctrine of the Faith has released another document describing how the priests and lay faithful can reconcile with the Church now that we're excommunicated. [See document]
I hate to say it, but I'm beginning to find the entire thing ridiculous and it smacks of Kabuki Theater or perhaps a story from Mad Magazine. Sad, yes, incredibly sad, but ridiculous as well.
Cardinal Fernandez has stated publicly in his writings that no one goes to hell. And then he threatens with hell fire anyone who remains with the SSPX. So you can be an active sodomite, perform abortions with impunity and still be praised at the Vatican, enjoy an adulterous union, etc. Does anyone in the magisterium even mention contraception these days? But if you belong to the SSPX you are destined for hell. Don't pass go; don't collect $200.
