Personally, I do ... it's interesting to note, though, that Emeth was not already dead when Aslan extended this opportunity to worship Aslan in truth to him -- so whether Lewis meant to imply that if you died in a state of sincere service to another god you could still be saved by Jesus is not clear.
...I think it is. The point in the book where Aslan talks about "believing" in him was very troubling to me, which is one of the primary reasons I didn't enjoy The Last Battle as a reader. Here's the passage that I think'd be helpful if we're going to continue talking about this subject
(If this is getting too off-topic you (mods) can move this to the books forum.)
(Talking to Emeth)
"The Lion growled so that the earth shook (but his wrath was not against me) and said, It is false. Not because he and I are one, but because we are opposites, I take to me the services which thou hast done to him. For I and he are of such different kinds that no service which is vile can be done to me, and none which is not vile can be done to him. Therefore if any man swear by Tash and keep his oath for the oath's sake, it is by me that he has truly sworn, though he know it not, and it is I who reward him..."
To be quite frank, this is outright
blasphemy. That's like saying in the real world, "If you swear by Allah while doing what Jesus asks, you're really worshipping Jesus."
No, if you swear by Allah you're worshipping Allah. If you ask forgiveness from Jesus and swear by Him you're worshipping Him. Plus, there's no such thing as "totally doing what another religion commands." Everyone has their quirks and superstitions. There are many Muslims who
aren't extremist, and are peaceful people who do things that Jesus would approve of. Are they really worshipping Jesus? No, they're worshipping
Allah.
This Lewisian teaching is not new; Billy Graham is sold to it (God help him), as he said something similar to that passage in an interview with a Catholic priest who agreed whole-heartedly about how there are many people out there who worship Jesus,
"...whether they know it or not."
This makes me seriously doubt whether Lewis was really a Bible-believing Christian, because if he believed the Bible he would have read and believed such passages as John 3:3,
"Except a man be born again, he cannot see the kingdom of God."
There's also a problem with people thinking, "Oh, I can just believe in Jesus and I'll be saved!" Really? Ever heard of James 2:19?
"Thou believest that there is one God; thou doest well: the devils also believe, and tremble."
It's not enough to just "believe." Satan believes in Jesus as the Savior of the world. He isn't an idiot, he knows this. The difference between that and getting to heaven is the fact that you must be
born again in Jesus' name, then believe and
follow Him as well as His teachings given to us in the Bible.
Lewis took this extreme of "knowing not" into his Mere Christianity (which I advise a few people to thoroughly read if they wish to know his true thoughts on conversion).
"There are people in other religions who are being led by God's secret influence to concentrate on those parts of their religion which are in agreement with Christianity, and who thus belong to Christ without knowing it. For example a Buddhist of good will may be led to concentrate more and more on the Buddhist teaching about mercy and to leave in the background (though he might still say he believed) the Buddhist teaching on certain points. Many of the good Pagans long before Christ's birth may have been in this position."
--Mere Christianity, p. 176, 177
What about the smoking gun passage totally against this in Acts 4:12?
"Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved."
I'm sorry, but Lewis was wrong.
Very wrong.
