Before the info was deleted, Nemmersdorf had posted info from Bishop Williamson denying knowing anything about this. Then PetrusTOP posted correspondence that was supposed to be between Bishop Williamson and the 'seer'.
I don't know "PetrusTOP" but I know that Nemmersdorf is a solid source, for example when it comes to quotes from Bishop Williamson. So when Nemmersdorf quotes Bishop Williamson saying he doesn't know about this private revelation, then the Bishop doesn't know about it.
Dear Nemmersdorf, since you also read Cathinfo and we Cathinfo users didn't see your posts on the liberal Ignis Ardens forum, could you please re-post your information from our good Bishop Williamson about this private revelation here on Cathinfo? Thank you in andvance!
