I've been told that in the Novus Ordo, being married by an SSPX priest has always been valid grounds for an annulment. How many annulments like this are there in St. Mary's?
It's true, the Novus Ordo does not recognize any marriages of the SSPX (yet they do for Prots???) nor "Resistance" or probably any Sedevecante marriages. I know this first hand and have been told so directly.
As for SSPX divorces (a.k.a. "annulments"), an older cleric told me the rate is around 1 in 5, if memory serves me correctly. I don't know if this is only applicable to the marriages he officiated or just in a particular major northern U.S. State he was in or the whole of the SSPX
