they were originally Vatican 2 Catholics and they still attend Byzantine Catholic Masses for Sacraments. So your assertion that they've never received the Sacraments is blatantly false.
And using Feeneyite as a pejorative is a bit odd when there are absolutely no ex cathedra statements in favour of BOD but dozens against.
Sorry for the above incorrect statement. However, the fact that the Dimond Brothers (who possess a "holier than thou" attitude towards all non-Feeneyite Catholics) still attend Byzantine Catholic Masses for Sacraments
makes them hypocrites, plain and simple.
They are receiving sacraments from Novus Ordo clergy in Novus Ordo churches, then have they audacity to continuously and publicly say that all
non-Sedevacantists are damned to Hell. Thus, they are receiving sacraments from NO priests who are damned to hell. You would think that they would at least
go to a Sedevacantist mass to receive Sacraments (since they make a living trash-talking the NO Church). Since they keep going to NO Churches to receive sacraments, why
should anyone take those 2 seriously??
Pope Pius IX spoke on BOD (check Denzinger). I suppose the Dimond Brothers, as well as other Feeneyites, thereby consider Pope Pius IX to be a "false pope."
Also, Fr. Feeney was excommunicated "for disobedience and not
for his position"-- that is true. However, that's only half of the story. Feeneyites usually fail to mention the other half of the story: Fr. Feeney disobeyed an order to come to Rome and defend his position
(because even he knew
that he had no theological leg to stand on and that he would be vigorously questioned on his untenable position by theologians much more learned than he).
