We don't have any substance in our hands concerning this alleged private-apparition.
If something sounds nice or logical (which isn't the case here) it's still no proof whatsoever for a private-revelation. Most private-revelation are false ones, by the way. So let's be very critical.
Nemmersdorf's report on Ignis Ardens about Bishop Williamson's words (which was posted somewhere here too) underlines that the good Bishop doesn't have or doesn't want to have anything to do with this alleged private-revelation. That'll do me fine.
Well, the front lines inside the SSPX are clear since the three bishops' letter and the reply from Menzingen in April 2012, with or without alleged private-revelation.
Our Lady helps those who stand behind the traditional Catholic Faith anyway. That's why the declaration of the five brave priests mentions in its first line Our Lady.
This excellent declaration of the five priests says what needs to be said. Let us stay on topic, instead of derailing this thread, too. (Those who must discuss the alleged private-revelation could open a new thread, please...!)
