I would be interested in hearing what he says on this topic in more detail given I tend to give credence to what our Traditional Catholic clergy teaches on Faith and Morals (although I still think this topic is not settled Church teaching).
It would be interesting to see how he comes to his conclusion. Because even though he does mention "exceptions" the whole phrase he used was "the remaining Jєωs will convert collectively, i.e. as a whole, albeit with exceptions." Yes, that doesn't mean 100% conversion, but it also gives me the impression that he's not talking about a large number of exceptions. If anything, he seems to be suggesting something very close to a mass conversion.
Since you seem to have contact with him, perhaps you could ask him to speak more to this part of his prior EC too (and post it with his permission)? Maybe he could also speak to whether this is settled Church teaching.
Since there were personal identifiers in His Excellency's email, I chose not to quote the entire email verbatim and I did not want to "swiss cheese" the email with ellipses (…). Even though my website is shoahed, I am working to revive it and so still believe preserving anonymity (even after my death) is important for the safety of my family. The vengeance of Satan and his ѕуηαgσgυє is unmatched.
That said,
as long as the exceptions are acknowledged, I have no problem with the unpredictable number of converts now, later, or on The Last Day.
Whether 1 conversion or 14 million conversions, I care not. As I have said, I welcome every
sincere conversion. Equally true,
I oppose every marrano who brings Jєωιѕн conceits, deceits, and heresies (e.g., David Moss's "Hebrew-Catholics" exceptionalism; Schoeman's racialism [see the files attached previously and also below in this post.)
and Judaizers (e.g., MarkM/Nishant and josh987654321)
who all do violence to our Faith.
Understood?
