The fire will assay the quality of everyone’s work; if his work abides which he has built thereon, he will receive reward; if his work burns he will lose his reward, but himself will be saved, yet so as through fire. (I Corinthians 3:13-15)
The works of one’s life are tested by fire. The person is not. If there is a purgatory, this verse doesn’t teach it.
