this article. Relevant extract below:
"The Home-aloner group has gone through an extraordinary (and very bad) transition from trying to create popes to giving up and declaring that Jesus Christ is shutting down His Church. For a number of years, prominent Home-aloner and Conclavist Ken Mock had travelled the countryside seeking some sufficiently untainted clergyman to be made into a pope. After one failure with Michael Bawden ("Pope" Michael 1), he had moved on to making another with Fr. Lucien Pulvermacher (a brother of Fr. Carl Pulvermacher and other priests), who declared himself to be "Pope" Pius XIII. Since he was not a bishop, rather than await the arrival of some bishop (somehow), he invented a way (so he thought) to make himself a bishop, so that he could then be a "Bishop of Rome." He had found some rare case when a mere priest had successfully ordained another man to the priesthood, and somehow thought that perhaps under such extraordinary circuмstances a priest might already therefore have the episcopal mark on his soul. Apparently, a priest could make another priest, but for a priest to make a bishop means that he is attempting to give that which he does not himself possess, something which is theologically impossible.
After this failure, Ken Mock began scouring Europe and the rest of the world seeking his "untainted" bishop, and as it has become clear to the Home-aloner community that there remains none such to be found who would also be willing to reconstitute the Church, this is why Home-aloners now claim that the Priesthood and the Sacraments (other than Baptism and Marriage which can be done by laypeople) are simply scheduled to disappear. They have closed in on themselves and vanished into heresy. As for the new "popes" themselves, their universal failure to provide credible alternatives to John Paul II has quite well demonstrated that the Conclavist approach will not work. But of course that stands to reason. With Vatican II on the books, it is impossible for any bishop to possess universal jurisdiction and with that the Papal charism of Infallibility. Some of them might possibly have made good popes had the office really been attained by them, but lacking Infallibility they have vanished into errors themselves, albeit far less serious ones than those held at the Vatican.
Ironically, though the home-aloner position is most often associated with sedevacantism, one of the main, if unacknowledged, intellects behind the home-aloner group is neither a sedevacantist, nor (strictly speaking) a home-aloner himself. This would be the Abbé de Nantes. Despite the value of some of his works in demonstrating the heretical nature of the new religion and its main proponents, the man himself has inexcusably become critical of Abp. Lefebvre and all other bishops and clerics who have heroically sustained the valid and lawful apostolic succession. Taking a grotesquely overscrupulous and pharisaical stance against performing any clerical function without Modernist Vatican approval, a number of young men in his group, though eminently qualified to serve as priests, go unordained. Thus his followers have been effectively neutralized against taking any positive constructive action in this crisis. If it were up to him, the very future of the Church itself would be held hostage by the Modernist heretics."
I want to clarify that I'm not a Conclavist and I recognise Archbishop Lefebvre as a true Bishop that the Catholic Church was lucky to have in these times. It's just that there are no traditional priests or bishops in Malta. All are ordained according to the post-Vatican II rite.
