Douglas Wilson tells a story that sounds like a joke, but the punchline is eternally true.
Once there was a Presbyterian minister who had made the whole topic of sola fide his special field of study. He had mastered the subject, as far as any mortal man can be said to have mastered anything. After a long and fruitful ministry, he eventually did what all Presbyterian ministers do, which is to say, he died.
As he approached the pearly gates, he was mildly surprised to see that St. Peter was there, just like in all the jokes. But he was, he thought, prepared to roll with it because, after all, he was going to Heaven.
Right next to St. Peter was a long wooden table, of the kind you see in examination rooms. A chair was pulled out for him, and on the table was a thick test, and a pencil next to it. As he walked up to St. Peter, he was greeted warmly and the set-up was explained to him.
“We have prepared a small fifty-page test for you,” Peter said. “Because we believe in grace, we decided to prepare a test for you that is right in your wheelhouse. This entire test is dedicated to the subject of sola fide, a subject you have been studying for forty years, I understand. If you get a perfect score, you may enter into joy.” With that pronouncement, Peter handed the pencil to the minister, and gestured to the waiting chair.
The minister held the pencil for a moment, thinking about it, and then quietly, without a word, he handed the pencil back.
A smile played around the corner of St. Peter’s mouth. “You pass,” he said.
