The Focus on the Family organization has a similar background, but I don’t think they would have allowed their their personal differences in beliefs to enter into a radio drama based on a book by C. S. Lewis.
Fair enough, although Col Klink in his earlier post said he'd noticed some other Radio Theatre adaptations that he'd "definitely describe as reflecting Focus on the Family's worldview rather than that of the original author", so I assume they sometimes do make changes on theological grounds. But I haven't heard any of their other productions, so I can't compare (and I wouldn't want to take this thread too far off topic anyway).
Also, I don’t think the Narnia books have any ideas from doctrines specifically of the Anglican Church other than those that are generally endorsed by all Christians.
They do have a very broad appeal — coming, as they do, from the basis of what Lewis himself famously called "Mere Christianity" — but I have encountered Christians who object to certain theological implications in them. I know I've mentioned elsewhere before that in one Narnia commentary book I once read, the author (who was otherwise highly complimentary of everything else about the books) was openly very disturbed by the fact that Emeth was allowed into Aslan's country in The Last Battle, when he had spent his whole life worshipping a false god and had never professed faith in Aslan during his earthly life. That's one point on which different denominations disagree — do those who haven't accepted Christ in this world get a second chance to do so after death? — and that particular commentator clearly considered Lewis's stance to be wrong.
Or for another example, a few years ago I had a back-and-forth exchange on another website with a reader of the Chronicles who insisted that Susan must have gone to hell at the end of The Last Battle, because she wasn't among those who were allowed into Aslan's country, and (this commentator kept saying) "it's the end of the world and everybody is supposed to be there." It became apparent she was coming from a tradition that teaches that those who have died are asleep until the final judgment, at which everyone who ever existed will be sent to either heaven or hell, all at once. That, however, as I explained to her, isn't the Anglican teaching and it isn't what Lewis was trying to portray in the book, if you read it carefully. (And for those who wrote to him wondering about this point, he explained that Susan is still alive in our world at the end of the story, and maybe she will get to Aslan's country in her own way.)
Now this is going off topic, so I'll shush up and get back to listening to the radio adaptations shortly!
"Now you are a lioness," said Aslan. "And now all Narnia will be renewed."
