Overall, I don't even want to get caught up in the discussion haha.
But mainly, I just wanted to say that The Aetherlight, as a game, is already keeping pretty close to the Biblical narrative in terms of what it chooses to portray? I mean, as a game, it can't play each story word for word, and that really goes for everything else.
I don't have much of an opinion on whether or not Aether actually portrays the Holy Spirit in The Aetherlight. But if it is, I wouldn't have much of a hard time believing it if there's evidence. Not that it rightfully portrays each and every aspect perfectly, but if there's a good chunk of evidence to support that the Devs patterned Aether after The Holy Spirit, then yeah.
Now I'm just saying things in different ways over and over again haha. That's just my two cents.
