Mimara seeing herself as holy was probably done intentionally to combat this very argument. Without that piece of information, there's not much to defend the idea that TJE is objective in some way.
But given her self loathing, self hatred, upbringing, and teaching of the church, she is literally the last person who would see herself as Holy. She is even disgusted, or at least concerned, when she sees her image.
What's all this talk about normal people thinking Chorae being holy? They were derived from the Aporos, which is not just sorcery but Nonmen exclusive, and produced by the Inchoroi. They don't exactly have a lineage for holiness.
The thousand temples uses them to kill sorcerers, so they are a useful tool. 'Tears of God' , yeah, but they are still blasphemous objects. If people in the three seas think they are holy objects, I've definetly forgotten any references to that effect.
Objects of enourmous importance, vastly expensive to obtain, and extremely useful to killing schoolmen, but holy?
