This episode of the Vortex claims that McCarrick at least had a hand in its drafting. While this is news to me, it certainly is no surprise. He is a signer.
Word is afoot that the Vatican will soon be deciding whether or not McCarrick will be laicized. For the sake of all concerned, including McCarrick himself, I pray that he is laicized and that he take honest looks at the state of his soul, for he hasn't many years left in which to repent and do some reparation.
