This topic doesn't make any sense. Bishop Williamson, in fact, no bishop, is going to just show up somewhere and confer confirmations or ordinations. At the very least, someone has to ask the bishop to confer the sacraments. So, it would seem that the ball is in Fr. Pfeiffer's court. He is going to have to find a bishop willing to ordain his candidates and he is going to have to make the first move and ask that bishop.
Are there any anti-sedevacantist bishops that Fr. Pfeiffer hasn't condemned as dangerous to the faith? I say "anti-sedevacantist bishops" because everything I've heard from Fr. Pfeiffer is that he first condemns sedevacantists before condemning Bishop Williamson. When this "Resistance" first started, I thought Fr. Pfeiffer was its leader based on what I initially read here on CathInfo. It wasn't until a few months had passed that some of the members of CathInfo explained that this was not the case and that Fr. Pfeiffer really wasn't leading all or even most of the the "Resistance".
Whether Fr. Pfeiffer's seminarians ever receive ordination will completely depend, I think, upon whether or not Fr. Pfeiffer can swallow his own pride. From his conferences I've seen on Youtube, I'm not so sure that he can or will.
