Jehanne said:I agree with him, that recent Popes have been material heretics, just not formal ones, as only the Church can make formal judgments with respect to the latter.
It isn't an official decision by the Church that makes someone a formal heretic. I think you're confusing a Romish declaration that someone is a heretic with their status as a material or formal heretic.
A formal heretic is made formal by knowing the difference between orthodoxy and what he preaches, and continuing to tenaciously preach it anyway. That would mean that all the Popes since at least Paul VI are formal heretics, since they went against the fundaments of the Catholic religion. PERHAPS Pius XII was a material heretic who thought NFP was a legitimate development of doctrine. It seems that no one, no "bishops" anyway, questioned him on it.
A material heretic only has to be obstinate in his heresy after a couple of reminders to become formal. That means that not only the VII and SSPX clergy but the sedevacantist clergy are formal heretics. The VII clergy have been accused of heresies on a daily basis and don't respond, showing they are tenacious in their error.
The sedevacantist clergy have been shown by the likes of the Dimonds and Ibranyi and others to be holding heresies as well ( salvation in other religions i.e. the Baltimore Catechism heresy and NFP ). Since they defend both errors, I don't see how they can escape being formal heretics. It doesn't matter if the Feeneyites are accusing them of certain errors that aren't really errors; because they are also accused of errors that really are errors, which honest, good-willed men of the cloth should concern themselves with.

What you are saying, Jehanne, is that you are waiting for an official decision about whether these "Popes" are heretics at all, and you are assuming that can only come from Rome, i.e. from a true Pope and re-established Church. But a bishop or group of bishops can declare a Pope to be a heretic. And the sedevacantist bishops, despite all of them that I know of perhaps being heretics themselves, have done so. I know it's not very encouraging, but it's all we've got.
Laymen also can recognize the heresy of a "Pope" without being able to make it a matter of law that he is officially outside the Church. As you know, sedevacantists will tell you that heretics excommunicate themselves. That means the majority of the Church must have defected before Vatican II. Very few people are excommunicated by name.
