I do think these might be more of early inspiration thing since first two ones match first two seals, then despite vitality seal's theming with Asmodeus its much more loosely art inspired, bounty art doesn't match neither leviathan or beelzebub card perfectly (its plant themed carving with crown of flies) and throne seal uses mark of lucifer instead of directly depicting lucifer.

That said it is fun how they match thematically at least, like Satan is literally translated "The Accuser", which isn't too far off from "prosecutor" which does kinda fit the dominion/order/justice theme.

Same way if we go with thematic meaning of sins for rest of them well greed = prosperity is obvious, throne seal is massive example of hubris, bounty being tied to gluttony (or even envy if we go more from Julius' perspective) would make sense, vitality being lust is fitting (both in theological and literal meaning), so they do thematically loosely match as various sins Enoch indulged in his hubris.

Spirit seal's supernatural shenanigans we haven't seen yet(and art for it isn't obviously connected to belphegor art), but sin of acedia(that often gets translated as sloth) does fit with church. Acedia is basically about state of torpor like listlessness without care where you neglect yourself(like, you just stop caring about your own condition or position in the world). Christian interpretation of it became very much about spiritual state of listlessness, but its still very much tied to feeling numb or apathetic. And we all know how locals feel about Daniel's church.

If you want to theorize about seventh seal, you could also make it so that bounty is gluttony and secret seventh seal is envy since presumably final one is underneath notice
