The Hobbit does have Christian themes.
Tolkien was a philologist and a linguist much like myself. He was in fact so Christian that he converted C. S. Lewis to Christianity who had overt Christian themes in his literature. In school they had a creative writing group known as “The Inklings”. He did not overtly put Christian themes in his book but upon later inspection as he was editing it, he had to admit that the patterns were there.
People say, “Look, God’s not mentioned in The Hobbit or Lord of the Rings. There’s no churches, no priest, no Bible. There’s no Jesus. How can you say it’s Christian?” And I said, “Here’s the deal. You can’t see that it’s Christian because you live in the Christian world where there is right and wrong and there is truth. I don’t know if you know any friends who don’t believe that there’s right or wrong and don’t believe there’s such a thing as truth. That’s the non-Christian world.” I mean, that’s the world without God. J. R. R. Tolkien SOURCE HERE
Something that C. S. Lewis said actually helped me when I was psychologically profiling Richard Dawkins. It helped me understand the environment that he grew up in and the impact that environment had on him. At that point I understood what it was that he was concealing about himself based on his rhetoric. Dawkins grew up in the same Atheist environment that Tolkien and Lewis grew up in but instead of rebelling against it his weaker mind bowed to it.
…If you have not been at such a school as Wyvern, you may ask what a Blood is. He is a member of the school aristocracy. Foreign readers must clearly understand that this aristocracy has nothing whatever to do with the social position of the boys in the outer world. Boys of good, or wealthy, family are no more likely to be in it than anyone else; the only nobleman in my House at Wyvern never became a Blood. Shortly before my time there the son of a very queer customer had been at least on the fringe of Bloodery. The qualifying condition for Bloodery is that one should have been at the school for a considerable time….
…At some schools, I am told, there is a sort of dyarchy. An aristocracy of Bloods, supported or at least tolerated by popular sentiment, stands over against an official ruling class of prefects appointed by the Masters. I believe they usually appoint it from the highest form, so that it has some claim to be an intelligentsia… Their position was emphasized by special liberties, clothes, priorities, and dignities which affected every side of school life…. …At the Coll the lowest social class of all were too young, therefore too weak, to dream of revolt. In the middle class—boys who were no longer fags but not yet Bloods—those who alone had physical strength and popularity enough to qualify them as leaders of a revolution were already beginning to hope for Bloodery themselves. It suited them better to accelerate their social progress by courting the existing Bloods than to risk a revolt …
It is possible that some readers will not know what a House Tart was. First, as to the adjective. All life at Wyvern was lived, so to speak, in the two concentric circles of Coll and House. You could be a Coll pre or merely a House pre. You could be a Coll Blood or merely a House Blood, a Coll Punt (i. e., a pariah, an unpopular person) or merely a House Punt; and of course a Coll Tart or merely a House Tart. A Tart is a pretty and effeminate-looking small boy who acts as a catamite to one or more of his seniors, usually Bloods. Usually, not always. Though our oligarchy kept most of the amenities of life to themselves, they were, on this point, liberal; they did not impose chastity on the middle-class boy in addition to all his other disabilities. Pederasty among the lower classes was not “side,” or at least not serious side; not like putting one’s hands in one’s pockets or wearing one’s coat unbuttoned. The gods had a sense of proportion.
The Tarts had an important function to play in making school (what it was advertised to be) a preparation for public life. They were not like slaves, for their favors were (nearly always) solicited, not compelled. Nor were they exactly like prostitutes, for the liaison often had some permanence and, far from being merely sensual, was highly sentimentalized. Nor were they paid (in hard cash, I mean) for their services; though of course they had all the flattery, unofficial influence, favor, and privileges which the mistresses of the great have always enjoyed in adult society. That was where the Preparation for Public Life came in. It would appear from Mr. Arnold Lunn’s Harrovians that the Tarts at his school acted as informers.
As I have hinted before, the fagging system is the chief medium by which the Bloods, without breaking any rule, can make a junior boy’s life a weariness to him. Different schools have different kinds of fagging. At some of them, individual Bloods have individual fags… …Fagging with us was as impersonal as the labor market in Victorian England; in that way, too, the Coll was a preparation for public life. All boys under a certain seniority constituted a labor pool, the common property of all the Bloods. When a Blood wanted his O.T.C, kit brushed and polished, or his boots cleaned, or his study “done out,” or his tea made, he shouted. SURPRISED BY JOY, C. S. LEWIS AUTOBIOGRAPHY
