So, you are arguing that there is zero, zilch, nada Christian narrative interloping within LOTR? My first instinct is to naysay, but I shall google first, then naysay.
Google results for: Lord of the Rings christian symbolism: 88 million results. The first few seem compelling to me. I’m going to go ahead and declare victory and await your official protest.
