The debate is interesting and instructive. The moderator, a gracious man, seems stylistically to be on a radio show from the 40s (the crackling sound quality heightens this effect as he speaks); his is an oddly florid tone. But Camping and Walvoord are both straightforward and to the point.
I could do a fairly accurate job of summarizing the six hours like this: for the most part...
- Walvoord keeps reading Scripture and saying "I think it means what it says"
- Camping keeps working his decoder-ring hermeneutics to make Scripture not mean what it says
For instance, here's a big clue: Listen for Camping repeatedly cautioning that we must read a passage "very carefully," or admonishing that we must "let the Bible interpret itself" rather than being devoted to a particularly school "or consensus." Sounds good? How can you argue against either?
Figures; Camping also says that the whole Bible is in parables, and he says that it is is very difficult to understand. Perhaps his version of Hebrews 1:1 reads that God "spoke in incomprehensible code to the fathers by the prophets"?
Also interesting: a caller asks about not knowing the day or the hour, and Walvoord answers. Camping simply declines to answer, which is an exception. It looms large in light of his recent deadly error.
Now, this may sound as if I'm writing the next bit for effect, but it is literally true: around the third and start of the fourth hour, I was thinking very appreciatively about what gentlemen both Camping and Walvoord were, and I was anticipating praising both for their behavior — and then the fourth hour started. Camping became completely unhinged. He launched an absurd attack on premillennialism, listing off a dozen dire accusations, including that premillennialism distorts the Gospel, denies Christ's kingship, denies Christ's lordship, denies the Bible's authority to explain itself, and a veritable pile of verbal manure.
Walvoord remained a gentleman in his response, more so than I would have. He said something like this: "My, that is a very impressive list of accusations. The only problem is that every one of them is false." No kidding.
Ominous note. There was a very poignant moment at about five hours and thirteen minutes. In the course of his answer, John Walvoord warned against the slippery slope that is spiritualization. He observed that many heresies and much liberalism involved the spiritualization of the Bible. And then he said this: "Once you start spiritualizing, there is no telling where you are going to stop."
He said this in front of Harold Camping who, decades later, after assuring people that the Bible guaranteed that Jesus would return to rapture His own on May 21, 2011, then said, "Oh yeah, about that — oops, sorry, it was actually a spiritual event."
A second poignant note is that in his attempt at a response, Camping actually — I kid you not — alluded to the Biblical admonition against many people becoming teachers (James 3:1f.)! You can't make this stuff up. If only Camping had heeded his own words.
Or listened to John Walvoord.
