Well, one argument of the sellout camp on this topic is that New-Rome would not have to lift the "excommunications" of Archbishop Lefebvre and Bishop Castro de Mayer anyway, because excommunications would cease (expire) with the dead of the excommunicated person.
One reply to that argument was, that when an excommunicated person dies, he would go to hell either way, so...
(I'm not sure however, if this really is the case.)
But since it's never been real excommunications, the best thing is to ignore any so called "excommunication" by the Newchurch (which is excommunicated herself, according to Archbishop Lefebvre), and also ignore any lifting of a so called "excommunication".
Alas, Menzingen forgot that. They forgot a lot of things, isn't it?
For sure I didn't sing an ordered Te Deum for the "lifting" of an non-existing "excommunication" back then. I rather started to smell that... Something is rotten in the state of Denmark.
And today we all smell it. Even across the ocean, isn't it, my US-American brothers in faith?
