Bit of a side note but Lucifer/Morning Star/Light Bringer wasn’t associated with Satan/ha satan/the prosecutor until at least Tertullian, if not Origen, and wasn’t much of a thing until much much later. In fact Lucifer was as likely to refer to Jesus up until at least the 4th Century, as in Hilary of Poitiers (“Tu verus mundi lucifer”) and the Exsultet (“May this flame be found still burning by the Morning Star: the one Morning Star who never sets, Christ your Son”).
As such I feel like there should be a little room for your Asmodeuses and your Beelzebubs and the like as they have about as good a claim to being Satan as Lucifer does, or heck, even as much as Satan himself does.
This has been your tangentially relevant Satan update. Thank you.
