I have explained this multiple times already. I will explain yet again.
The issue is not that it is absolutely a positive doubt, but it is the step before that, which leads to a positive doubt. Which cannot be dismissed.
You're an idiot and uneducated. There are only 2 types of doubt, in regards to sacraments. Negative and Positive.
Negative is based on feelings or imagination or facts which don't apply or heresay.
"Oh, I don't think Fr X is a priest because I heard that 20 years ago, he skipped a year of seminary."
"Did you check to see if this accusation of missing a year is true?"
"No." or "I don't know."
Conclusion -- this "doubt" is not based on reality. Negative doubts are not factual.
Positive doubt is based on factual events, or evidence, which
according to canon law, would make a rational person question validity.
The areas of positive doubt involve the sacraments themselves.
-- Was +Thuc a valid bishop? Yes. No one denies this.
-- Did +Thuc perform valid ordinations? This is what everyone questions, but you have to look at the details.
-- Did +Thuc perform the ordination ceremonies validity and completely? No one denies this.
-- Were the proper matter/form used? Yes.
-- Did +Thuc know who he was, where he was, what he was doing, etc? (i.e. was he sane?) Yes, everyone says he was sane.
+Thuc's PERSONAL/INTERNAL intention (which he allegedly made public, though this has never been confirmed) does not affect the sacraments. The Church's intention is all that matters. And the Church's intention = the form of the sacrament (i.e. the prayers which the bishop says).
The PERSONAL/INTERNAL intention does not affect sacraments, or else an atheist could not validly baptize. An atheist surely doesn't have ANY intention towards the sacraments, but he can still baptize. Why? Because the CHURCH'S INTENTION IS ALL THAT MATTERS.
There is no positive doubt in regards to +Thuc ordinations...the only *possible* exception being the Palmaranians in Spain... Outside of this, all of his Traditional rites were witnessed, and were involving other priests who were there. They had no positive doubts. They are eye witnesses.
