This is exactly my point about sitting in judgment over someone’s eternal salvation. I my view, that is stretching the text to say something the author did not intend. Of course, you are allowed to have a private interpretation of Isaiah 22 and the unpardonable sin, but I think you’ll find that your perception of the unpardonable sin is mistaken and misapplied, and I doubt you are going to find any prophetic support for that interpretation.
I think you have made your objections and points clear here, as have I in response to them, so I won’t continue to repeat what I’ve already written.
Another point you mention:
Ellen White warned us against taking expressions in the Testimonies beyond the application they were intended to occupy, such as taking counsel given for particular cases and circumstances and turning it into a universal rule.
In 1863, some ministers were making her visions “a rule by which to measure all”, a course she said she and her husband “have never pursued”. The result was that “some honest souls have been driven to take positions against the visions and against the body which they never would have taken had their cases been managed with discretion and mercy” (1T 382).
Twenty years later she republished that counsel under the heading “Wrong Use of the Testimonies”, opening with this: “Some who believe the Testimonies have erred by urging them unduly upon others” (5T 668.1). In 1906 she was still pointing people to the same chapter as her answer on “the proper use of the testimonies” (Ms 113, 1906).
She said the same specifically about health reform:
“We see those who will select from the testimonies the strongest expressions and, without bringing in or making any account of the circumstances under which the cautions and warnings are given, make them of force in every case.” (Ms 5, 1881)
That is precisely where we need to be careful when creating blanket church rules. A principle may certainly have a wider application, but that does not mean every strong statement from the Testimonies should be used as we sit fit to drive church legislated tests, especially in the absence of the living prophet.

That, Ariadne, is simply an impossible standard. Paul writes in 1 Corinthians 13:12, “For now we see through a glass, darkly.” None of us possesses a perfect understanding of truth. We can think we do, but at best, we can know just some truth, grow in the truth, and be led by the Spirit “into all truth,”. Our understanding remains incomplete, and while we still have self and the enemy to contend with, it is very much in our interest to remain teachable and capable of correction.
That is especially important where people have been exposed to confused, distorted, or erroneous teaching - where truth itself has been presented within a framework of error. A sincere person may fully accept the authority of Scripture while still misunderstanding particular doctrines, struggling to separate truth from error, or needing time to unlearn ideas they have been taught for years. That does not mean they are rejecting truth, much less that they have committed the unpardonable sin.
Ellen White herself warned against exactly the danger of treating our own understanding as though it were infallible:
“As a people we are certainly in great danger, if we are not constantly guarded, of considering our ideas, because long cherished, to be Bible doctrines and on every point infallible, and measuring everyone by the rule of our interpretation of Bible truth. This is our danger, and this would be the greatest evil that could ever come to us as a people.” 1888 830.1
We cannot completely separate truth from our perception of it. If we could do that perfectly, none of us would ever misunderstand Scripture and we would have no need to remain open to correction. We are not inspired prophets.
There is therefore an important difference between requiring a baptismal candidate to understand and sincerely accept the foundational teachings of the gospel, and requiring them to possess a “perfect understanding” of every doctrine, principle, and point of present truth as interpreted by the church - or, in this case, according to John Thiel’s interpretation of those things.
