The thing that I was so interested in - that I wish had been explored further and used in some sort of theme-reinforcing manner - was the disconnect in understanding between the supernatural entities and the humans they sought to influence.
Watching Aziraphale first try the ox rib really emphasized this to me: here he is, living among humans, trying to influence them in a positive manner, and yet he clearly has zero experience with what it feels like to actually be one. Down to the very senses. He nibbles some meat, and he absolutely loses his mind like... have y'all ever read the Animorphs books? Back when y'all where kids. It's like in Animorphs, when Aximilli the Andalite first tries eating while in a human morph. The sensation of taste is utterly alien to him and incredibly overstimulating; it becomes on ongoing joke throughout the series. Ax and eventually other Andalites frequently become overwhelmed by the (to them) intense sensation of taste.
That's the vibe I got: Aziraphale is supposed to manage and influence these humans, but he's not even aware of what sort of sensory experiences they have on a daily basis. And that extends to all of the other angels, as we see with Gabriel refusing to try food in S1 and Muriel anxiously looking at their cup of tea in S2.
And this extends past the physical and into the emotional. The Job plot was so fascinating to me because I got the sense that the angels just legitimately did not understand why replacing Job's children was a problem. Not in a mean way, or a cruel way. They just genuinely did not understand why this would bother someone. It's upsetting to us, but it's also... oddly endearing? Like they're a strange form of children.
But it's also so strange! They're angels, continuously bathed in God's love. Shouldn't they know what love is, how it affects people, the importance of those connections? ...or is their God's love very much different from mortal love? From the love we animals have for one another? And if that's the case, then do they know that? And once they learn it, do they prefer one over the other?
Gabriel abandons his post - and indeed his home in heaven - so that he may enjoy Beelzebub's love. Love that is very much recognizable to us mortals. He learns of it and experiences is and chooses it over being the supreme archangel. That's fascinating, isn't it? Him giving up a position that is relatively close to God and her love to engage in a more mortal love with a demon.
With Job, Aziraphale and Crowley are the only ones who recognize how twisted the divine plan is. They're the only ones who have lived on Earth and experienced relationships outside of the sterile, hierarchical love of heaven and... whatever hell has going on.
I've seen the theory floating around, that the Job incident was a test for the angels. And that only Aziraphale and Crowley (ironically) passed. And that's such an interesting concept to me! God trying to teach her celestial children about an organic sort of love in this strange, eldritch manner. Them not understanding it, save for the one angel who sometimes pals around with a demon.
I just wish it had gone somewhere. I wish that the disconnect between love on Earth and whatever God gives the angels was addressed. I wish the fact that Aziraphale is so much more at ease on Earth and with Crowley - so much happier and more relaxed and very much looking like he's actually loved rather than just saying he is - was addressed. I wish the coldness of the other angels, their unhappiness and anxiety despite living so close to a supposedly loving God, was addressed.
It was just such an interesting concept to me. The notion that God and her angelic children didn't actually experience or understand love nearly as well as they thought they did. While the angel and demon mucking about on Earth with all the mortals understood it just fine.
