What I object to is luciferian doctrine being unknowingly fed to kids. As a youngster, I chose to read both LOTR and "The Lion, the Witch and the Wardrobe(LWW)". Both Lewis and Tolkien were recommended to me in school. Some of my English assignments even involved reading anti-Christian novels.
I was searching for answers in my spirit and would much rather have been able to talk about the big questions of life with a Holy-Spirit filled person than get lost in fantasy.
This is what the Jesus says about those who say they follow him:
For the gate is wide and the way is easy that leads to destruction, and those who enter by it are many. (Matthew 7:13)
Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. (Matthew 7:21)
Another instance:
then said one unto him, Lord, are there few that be saved? And he said unto them, Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able. (Luke 13:23-24)
I knew Tolkien was Catholic. I make no assumptions about Lewis. They were also both part of the same writing club and were friends.
The mythos for Middle Earth is definitely pagan-ish but, if memory is not mistaken, pagan spirituality is not promoted as Lewis does in LWW. Tolkien does use real runes for dwarvish language though. He had a love of languages/poetry and felt England should have its own Kalevala, the Finnish epic poem. A love for pagan myth is kinda concerning and could indicate something ...
However, "The Lion, the Witch and the Wardrobe" gives away Lewis' love of the occult.
CS Lewis does the more spiritually dangerous thing -- he promotes luciferian themes and witchraft within a Christian wrapping. The major one being the messiah-like character in Aslan, who is a spiritual adept. Aslan and the whole plot erroneously cements LWW as a Christian book for many people.
By presenting luciferian ideologies that could be mistaken as Christian (by unassuming kids or adults with no discernment), Lewis is creating spiritual confusion. Even if it is unintentional, there is spiritual deception involved which leaves door open.
Further research reveals Lewis' ongoing interest in the occult.
I would not read either to kids.
