One of the readers of this blog (a guy named "Dan") alerted me to the fact that he tried to track down "Possum Kill, NC" on the map, and couldn't do it. I tried to do the same, and couldn't do it either. I also didn't find it mentioned on any websites or in any books.
There are two exceptions:
I. The first exception is that Ergun Caner himself uses the place as an illustration in his contribution to the Popular Encyclopedia of Apologetics, p. 327, left hand column, first full paragraph.
With some sad irony, Ergun Caner ends that entry with the following paragraph:
It is essential that the Christian diligently attempt not to use logical fallacies. The Bible implores the Christian to speak truthfully and without deception. Indeed, Jesus said "you will know the truth, and the truth will set you free" (John 8:32).(p. 328)
Dr. Caner is right about that. It is one of many good things that Dr. Caner has to say. People may get the wrong idea from my posting articles that are critical of Dr. Caner, but I do not consider the man's work worthless. I do hope God will bring him to repentance on the issue of autobiographical embellishment.
II. The second exception is another blog also trying to track down the same point (link to blog). As of when I published this, no one had found an answer there either.
I think Caner is just trying to speak generically about a rural town. I've heard others use statements like "Smalltown, USA" or "Podunk, [state]", and things like that. I would interpret Caner's words here the same way. I think his usage of it in the encyclopedia entry backs up my understanding. I don't think Dr. Caner meant for people to take the name of the town of his father-in-law literally as being "Possum Kill." It may technically not be true, but I wouldn't classify it in the arena of a lie or an embellishment.
UPDATE: In the testimony at the following link, Dr. Caner insists that the name of the town is "not a joke" (link). That's slightly disturbing, although arguably it was supposed to be for comedic effect.
FURTHER UPDATE: Caner mentions "Nostril, Texas" and "Earlobe, Arkansas" in this clip (link). "Possum Kill" would just be a similar fake place name.
ADDITIONAL UPDATE: When speaking to the Ohio Free Will Baptists, Caner said "this is not a joke, this is the truth, anybody from North Carolina will know this city, her father is from Possum Kill, NC, right near Smithfield." (link).
