The American resistance seems to have aligned itself with at least one heretical Feenyite chapel. The CMRI chapels I’ve been to have signs posted advising that they will not allow non-Catholic Feenyites to receive the sacraments. So the CMRI is a much safer course in the U.S. if you wish to remain Catholic.
Who in particular has aligned with which "Feeneyite" chapel? You toss the term heretical around too freely. Father Feeney's distinction between justification and salvation has never been condemned. And at best one could argue that BoD is theologically certain but not
de fide. I don't agree it's even that ... but the bar for heresy is very high. Yet Father Feeney does not reject BoD per se but states that it suffices for justification but not salvation. Disagree if you will, but that position has never been condemned.
