Well yes, but if you read the article by James Larrabee referenced in my previous post you will see that Fr Chazal's position has already been refuted.
I read your article. It was as expected, the same old arguments again and again. I did find this part of it to be absurd though:
"Along the same lines, the papacy must be accepted by the elected candidate, even if validly elected. Yet it can be argued that the new "popes" from John Paul I onwards did NOT accept the Roman Pontificate, but a new, conciliarist, "updated" papacy, a consitutional monarchy or figurehead office of some sort, or as De Nantes would put it, the headship of MASDU. Thus, they in no way accepted the papacy, nor have they actually exercised it. This was clearly manifested in their mere "installation" rather than in the traditional coronation, and undoubtedly other ways. As for Paul VI, it could easily be said that, if his heresy was not already manifest, he clearly manifested his rejection of the papacy by very publicly and formally removing (permanently) his tiara in the presence, I believe, of the whole council. Given the importance attached to ceremony and external signs and symbols both by reason itself and by the Church in her whole external life, one could hardly imagine a more certain way of resigning the papacy AS TRADITIONALLY UNDERSTOOD than this act. Certainly from that time, the papal authority as instituted by Christ and exercised by 260 pontiffs has no longer been exercised by these "popes." It is precisely this de facto (at least) vacation of papal authority which has laid the Church open to the revolution of the Modernists. (Thus it is clearly the outcome of the Freemasonic plan exposed over 150 years ago, by the Popes themselves.) "
I am not an R&R supporter or a sedevacantist. I say I have doubts about the Popes since John XXIII and leave it at that. I expect the Church to rule officially on the matter after the crisis is over. One of the problems I see with sedevacantism is that anyone can for any reason declare that a Pope is a heretic and therefore ipso facto lost the papacy whenever they disagree with a Pope's teaching. What is the point of infallibility if it can be sidestepped by declaring the Pope to be a heretic and therefore not a Pope.
