rc1953 - I think you have contributed enough.
Ladislaus and prayerful - yes, these are examples of how john xxiii was in some ways torn between two sides.
I bring all of this up, because of the prospect this act presents to us traditionalists. +Williamson last year celebrated the pre 54 holy week within the context of his normal 1962 liturgy. And, I think there is something to this if john xxiii did somewhat the same. Because, we could argue that by the authority of john xxiii(his actions pre v2) we keep the practice of the pre 54 holy week. And, I am absolutely sure that I read that in one year of johnxxii's pontificate he celebrated the pre 54 holy week.
So, this could be somewhat of a unifying trad position. You appease those(nearly all of tradition) that either is attached to or prefers the pre 54 holy week. And, I think the R&R camp would be willing to give up st josephs name in the canon for the sake of drawing sedevacantists from their reclusive(I mean that respectfully) liturgical position. And, we could do this all in the name of john xxiii. Because, he did the exact same thing immediately before the council. And, keeping with tradition of before the council is really traditions argument. +Lefebvre's looked at it in terms of "the last acceptable liturgy". R&R needs to listen to the cries of the sedevacantists. And, I think +Williamson is doing that by celebrating the pre 54 holy week and not damning sedevacantists to hell. It is one thing to think about how to heal all of the divides in the church at large. But, I think it is probably best to start with tradition. I think those of good will in tradition would rally around such a liturgy/position.
The next hurdle is what to do about the una cuм(passionate subject). And, I think that for starters the solution is to leave out the local bishops name from the canon. Because, bishops can lose their office due to heresy. However, that is not the case when it comes to the pope. And, almost all of tradition believes that if the current pope were to renounce the heresies and undue the damage, he would be true pope. So, what better place to pray for such a person than in the canon of the mass. I think these are unifying positions. So, this is my thinking behind all of this. And, it gives incentive to do some digging. Because, believe me folks, I read this from a credible source. I did not dream it.
