During the Arian Crisis around 98% of the Western bishops apostatized.
We know that at least on one occasion around 4 thousand faithful Catholics followed St. Athanasius out into the desert to die miserable deaths rather than stay in communion with heretic bishops.
But surely millions of "Christians" were quite satisfied to stay comfortably where they were with their families, jobs, homes, etc. So, it can easily be surmised that 98% of the Western "Catholics" of that time apostatized too.
St. Hermengild's feast was just on April 13th. Here is what Dom Gueranger in "The Liturgical Year" has to say about him:
"It is through a Martyr’s palm-branch that we must to-day see the Paschal Mystery. Hermenegild, a young Visigoth Prince, is put to death by his heretical father, because he courageously refused to receive his Easter Communion from an Arian Bishop. The Martyr knew that the Eucharist is the sacred symbol of Catholic unity; and that we are not allowed to approach the Holy Table in company with them that are not in the true Church. A sacrilegious consecration gives heretics the real possession of the Divine Mystery, if the priestly character be in him who dares to offer Sacrifice to the God whom he blasphemes; but the Catholic, who knows that he may not so much as pray with ‘heretics, shudders at the sight of the profanation, and would rather die than share, by his presence, in insulting our Redeemer in that very Sacrifice and Sacrament, which were instituted that we might all be made one in God."

In summary, to partake of the Eucharist with heretics, or to receive it from the hands of one who is a heretic is a "sacrilegious profanation".
So, is the current Crisis worse than the Arian one, or not? If it is not, then it is very probable that most everyone on CathInfo is outside the Church and making a HUGE fuss about nothing.
