[Kreuz.net]The Society of Pius X is to blame: had they been a ɧoɱosɛҳųαƖ friendly group of protestants, they would have been invited into the chapel to the fanfare of trumpets.

[kath.net]Prelate Ludwig Limbrunner forbid pilgrims of the Society of St. Pius X into the Grace Chapel of Altötting to venerate. Indeed, they were informed by Prelate Ludwig Limbrunner, that they would only be allowed to pray silently in the Grace Chapel and otherwise must leave their banners outside. Thereupon the Pius Pilgrims said their prayers, despite pouring rain, in the courtyard of the Grace Chapel. For a short time there were some tumultuous disagreements in front of the Grace Chapel, according to the Neue Passauer Presse.
