The St. Michael's parents are good traditional Catholics trying to do their best for their children. But under Fellay and Pagliarani, the Neo-SSPX is being run by the "thought police." Pagliarani, in fact, interrogated all the nuns together and individually to make sure that their allegiance is to the Newchurch of the New Order. The history of the Neo-SSPX is that it treats its priests, religious, and laypeople like trash. If they overstep Bernie Fellay's dictatorial edits, they are almost literally thrown out on the street. They are not given time to wrap up their affairs and some funds in light of their previous service to find new lodgings. This is not Catholic; this is not even Christian. But this is the ilk that took over the SSPX and turned it into the Neo-SSPX after the death of Archbishop Lefebvre in 1991.
If this information is true (and it looks to be), then Fr. Pagliarani is using the same bully tactics that Bp. Fellay used against those who would not submit to the new agenda of collaborating with the conciliar church. It is very telling that Fr. Pagliarani interrogated the nuns in order to make sure of their allegiance to the SSPX agenda with the conciliar church.
It looks like Traditio has contacts in the SSPX (at least in the UK), since Traditio reported on this important development before Cath Info, Non Possumus, or the Resistance website in France. Though Traditio keeps saying that the nuns were against the "unconsecrated" and "invalid" Novus Ordo priests and bishops, I think it more likely that they just didn't want to compromise or have anything to do with the modernist conciliar church and clergy. Hopefully we'll get more info on the matter in the near future.
Maybe a prayer thread should be started for the nuns?
