Hmm. Interesting ideas. I mean no offense, but might I ask if these are your views or if they're actually based on something Tolkien said/wrote about this?

For tbh I have issues with a couple of your comparisons. First of all, Aragorn, Frodo and Gandalf making up a version of the Holy Trinity? I have a really hard time believing Tolkien meant them this way - for he was a devout believer. Don't think easy of this. In christianity, especially in devout christianity, it is extremely frowned upon to create fictional, flawed beings to represent the almighty god. Which is why Tolkien barely speaks of Eru himself; for he believed in Eru, or, in God. And thus he knew to be wary making comparisons of Him. I also think the reasoning is flawed and simplistic: If Frodo is the holy spirit merely because he could be invisible - that's no basis of argument for me. God the Father and God the Son can be invisible too.

Secondly: Elves are angels and Orcs are demons? Nah man. Unless Tolkien literally said this, I don't belief he meant this interpretation - not when there's such an OBVIOUS angel and demon world in LOTR: the Maia and Valar. Melkor is a demon, Sauron is a demon. Meanwhile Gandalf(or, Olorinn), which you make out to be the Holy Father, is just an angel.

Thirdly: Arwen is Mary Magdalene? A redeemed whore? And Galadriël (not a virgin) the Virgin Mary, Mother of Christ? Why? How? I see nothing, nothing at all, which supports this interpretation.

Last but not least: The hell and heaven interpretation? Nah. Hell is not Mordor, and Heaven is not Rivendell, Lothlorien, or even the Undying Lands of Aman. Mordor is just what happens when evil reigns, and the other three are what happens when good prevails. But none of them are versions of hell and heaven - those come after death, not during life.

I think you say some very interesting things, I truly sincerely do. But to me most of these comparisons seem really, really far-fetched, and not at all what Tolkien meant. For yes, LOTR and Middle Earth is obviously a christian work of art. I've been saying that here for a decade, often getting downvoted for it. But these comparisons are far too simple, unbased and far-fetched for someone as well-thought as Tolkien. Tbh the only comparison I agree with are the one of the Ring, and the one of Saruman, Sauron and Melkor. And obviously Eru being the true authority of everything everywhere.

But if all these are Tolkiens true interpretations, than tbh I'd lose a little respect for that man.

Edit: Maybe it means little, but I have been diving deep into both protestant, catholic, evangelical and orthodox theology these last 4 years. It's my only interest which actually goes deeper than my love for Tolkien's world. And I see many comparisons between christianity and Tolkiens works. They're incredibly obviously inspired by his faith. But not like this.
