Eric Metaxas, the author, gives it the old college try. But he isn't Jack Lewis. For instance Lewis would never have written:
And don't get me started on Out on a Limb! Oh, but Wormwood.I am ashamed to admit that when he did sidetrack me with this one though:
One must ever endeavor to capitalize upon ignorance, Wormwood. This is one of the chiefest weapons in our arsenal, and let me observe—and not without some glee—that the ignorance of contemporary Western Society in matters of history and theology both, is of an absolutely unprecedented greatness. Ask your average fellow in the street the slightest detail of a daft sitcom of forty years ago and he will move heaven and earth to supply you with the answer, and then will likely prate on with other similarly inane details—as if knowing who lived at 1313 Mockingbird Lane was his very passport to the Elysian Fields. Ha! But ask him to tell you about the Nicean Council, or ask him what are the Synoptic Gospels and you will suddenly find yourself in the presence of a weatherbeaten cigar store Injun! But then go ahead and ask him who played drums for The Monkees, or the name of that blasted itinerant peddlar on Green Acres and you will think yourself in the presence of a very Voltaire!1313 Mockingbird Lane is what? The home of the Munsters. The drummer for the Monkees? George Michael "Mickey" Dolenz, Jr. The peddler on Green Acres was Mr. Haney (first name varies). Thankfully I divined these things through Wikipedia, I didn't know them off the top of my head. Honest.
MINOR NOTE: C.S. Lewis's nickname was Jack. He didn't like either "Clive" or "Staples" for some obvious reason.
