the millenial (of one thousand years) reign of Christ, after which the devil
returns and they have it out again. Guess what happened after a thousand years
from when Celestia came to power?
Who is Jesus in your metaphor? Celestia? If so, who is Luna? And who are the mane six? Are they angels? If so, why are there only six of them instead of seven? Why are they defeating Discord instead of raining down plagues upon ponykind? What are the elements of harmony? Is Discord the beast? Why does he have only one head? Why does everything go back to normal after Discord is defeated? Or is Nightmare Moon the beast? If so, why does she also have only one head, why isn't Celestia/Jesus the one defeating her and who is Discord and why is he able to show up an entire season after the final battle?
You've misread Job. It's not Satan proper noun, it's satan as a title. Which was
typical of the time. The term we have today for it? Prosecutor. As for the evil
beings...let's look at both of them.
I specified to begin with that I was working with a protestant interpretation. If you want to use a jewish interpretation, we can try that...but since you've made reference to Revelations, I assume that's not what you had in mind.
Both of them use temptation, telling their foes to just give up and do as they say. Nightmare Moon is probably a replacement for the devil, but what about Discord? Well, that's easy. Mr Snake, what with his way with words, his changing of the very environment, his way of bringing out the worst in people.
1) When does Nightmare Moon tempt anyone?
2) The snake in Eden manifested no "environment changing" powers. He certainly wasn't more powerful than god. Yet Discord was apparently a threat that required both Celestia and Luna working together to defeat.
3) It seems inconsistent to suggest that Nightmare Moon is the devil and Discord is the snake in the garden, when Discord showed up fully a season after Nightmare Moon, and apparently both have the power to overcome Celestia. If your MLP scenario is played out in biblical terms, then man doesn't get expelled from the garden of Eden until after the battle at Armageddon, and the snake in the garden is more powerful then god.
4) While Celestia and Luna together defeated Discord once, when he came back a second time, they were apprarently
unable to defeat him, and the mane six had to defeat him instead. How is this a biblical metaphor? I don't recall the snake in Eden being bansished only to return more powerful than god, thus requiring somebody else to step in to deal with him.
5) If Nightmare Moon is the devil, how do you explain that she was able to banish/dispose of Celestia?
6) Who is Luna in all this? How do you justify the NMM/Luna dynamic? How do you explain her redemption? What biblical parallel exists to explain any of this?
Again, you have to totally ignore
so much for this to even casually resemble the bible, I just don't see this working.
Try starting out even just by identifying who corresponds to whom. Write me out a list of biblical characters and which pony character you think they're supposed to be. Because as it is, your proposals don't appear to even be self consistent.
