The passage has nothing to do with “Purgatory”
You omitted the caveat, "in my unlearned opinion"
"And account the longsuffering of our Lord, salvation; as also our most dear brother Paul, according to the wisdom given him, hath written to you: As also in all his epistles, speaking in them of these things; in which are certain things hard to be understood, which the unlearned and unstable wrest, as they do also the other scriptures, to their own destruction." 2 Peter 3:15-16
This smells like a disinformation campaign intended to discredit Pope Francis and make all us Catholics out here look like raving nutballs.
It has to do with a man whose "works" were kind of a mixed bag, but who - in the Day of the Lord -- is purified of the worthless stuff, which is burnt; he himself is saved, but only as through fire.
There is reference to judgment, and purification, and fire, and the soul being saved, but only after going through this purifying fire.
Am I understanding you correctly?
