Then there are the dogmatic Sedevacantists --
Those who believe that if you set foot in a non-sedevacantist chapel, you might as well be attending a protestant service. You are a sellout and possibly a heretic.
They think that attending a Mass where the 1962 Missal is used --or Benedict XVI's name is uttered -- makes you odious to God.
They believe that "the See is vacant" is another dogma of the Catholic Faith -- just like the Incarnation, perpetual virginity of Mary, or the Particular Judgment.
Such people are NOT sanguine about people making other choices in this Crisis -- in fact, they often condemn fellow Sedevacantists who are not "dogmatic" about it as they are.
Needless to say, such people are not welcome on CathInfo.
