This is new to me. The Devil is still out there freely doing his things. I can’t see this in the references you provided also.
In this area there are many myths from outside of traditional Catholicism that aren’t actually in Scripture or orthodox Tradition. Many of these stories come from Dante’s great poetic work “Inferno” in the late Middle Ages - which in turn is based on ancient cosmology which was assumed as true (but was in fact overturned by Galileo and others).
This is not to say they are incompatible with Catholic Doctrine - its just that they go further than orthodox tradition.
Scripture has little or nothing to say wrt these stories - though some texts are interpreted/tortured (in more “recent” times) to accord with these stories (eg Isaiah and Ezekial).
The Fall of Satan in Catholic Doctrine is purely a moral one and not some sort of spatio-temporal fall from one of the sub-Empyrean “heavens” (there are 6) to the sub-lunar realm (ie “earth”). St Paul, a man of his times, assumes the demons have authority over “the air”. This represents the higher element of the sub-lunar realm (he is a master of the deepest mystical forces of the created order so, by nature, stands well above man but well below the angels and where he dwelt in natural goodness before his ill will caused him to become more “fleshly” and less ethereal … hence the fall to earth).
Dante has him chained beneath the earth (Hell) because it is as far away as is possible from God (who dwells in the most spiritual Emyprean Heaven, beyond the 7th celestial sphere) and therefore the most “material” of habitats. Materiality is degredation for an angel. Even the earth itself abhors Satan - Dante has him chained at the bottom of a crater. Every star is an angel, located like rivets on one of the 7 crystalline spheres that rotate around the earth (hence 7 choirs or grades of angels, those farthrest from earth are closest to God). Why 7 spheres - probably because the ancients knew there were 5-6 celestial bodies apart from the moon that revolved around the earth (including the sun) in differing orbits with some closer and some farther.
These spheres were eternal and perfect and without change (obviously) and moved in circles (as all perfect things do). The earth (ie the sphere beneath the orbit of the moon known as the sub-lunar realm) in contrast was all change and decay. The moon, even though more ethereal than earth (literally made of the spiritual 5th element “aether”), was also subject to some change/decay as its rough surface visible to the human eye demonstrated. But here decay begins to halt and beyond the moon increasing perfection and unchangability takes over as we enter the 1st celestial heaven (the lowest).
This cosmology explains a few theological difficulties we have with Satans alleged “physical” fall from heaven. We hold that once we are in heaven, seeing God face to face we cannot sin any more. So how did Satan, in heaven, sin?
In this ancient schema Satan was, by nature alone, the greatest of the angels and therefore belonged to the outer 7th celestial sphere. But this is not God’s heaven. Gods heaven is unapproachable and lies on the other side of the 7th heaven. It is the Empyrean Heaven. So Satan did not fall from Gods Heaven. He never made it there like the good angels could.
The cosmology goes on and on and is very coherent and beautiful.
However Galileo and the Enlightenment caused it all to fall apart and we longer think of God or angels or devils being scientifically and spatially present in the cosmos (neither literally above or below the earth) like this anymore. Galileo showed the 7 spheres were in fact the orbits of planets (plus the sun) just like the moon. And these planets were not perfect. They had craters, they had their own moons. And they moved in ellipses not circles.
Now we talk like this only as a metaphor to explain the place of angels and demons in the moral order and how they influence us. Heaven is not above us in the physical cosmos as we sense it, Hell is not inside the earth.
We are still trying to re-unite the beautiful unity of material and spiritual creation that seemed so real and obvious to the ancient “scientists.”
But we are still at sea with no clue how that can be anymore.
Hopefully one day we will find the connections again.
Sorry for the ramble, it is a lifelong interest.
