“In the Epistle I read, the building had stone, metal, straw and stubble before, and emerges with stone and metal after. That is a purified building.”
In a sense, the CHURCH is purified - when Jesus separates the wheat from the tares. But the building in the word picture is not a man’s soul. No amount of twisting can turn it into a man’s soul. Nor is the point about purification, but revelation.
But of course, that is allowing the Apostle Paul to give the interpretation:
“But on the judgment day, fire will reveal what kind of work each builder has done. The fire will show if a person’s work has any value.”
And how DARE I quote the Apostle Paul, when we know the Catholic Church disagrees with him! < / sarcasm >
I made this point earlier to you. Purgatory is not only a process of individual purification of the soul but also is thought of as a church.

"You are God's building" is followed by a dozen "every man". Write your own epistle if you don't like this one.
