Further, can you elaborate on the issue of the relation between the name and meaning of Lucifer and that of Satan in that, if I recall, Judaism asserts that the latter name preceded the former whereas, I believe, Christianity claims the opposite?
You probably know the passage in Isaiah about the fall of the king of Babylon who is likened to the ‘morning star’ (14:12-18), right? Since early Christian days, there was already a tendency to interpret this text typologically as referring to the fall of the Evil One - Satan (though they also recognized the literal reading of the text).
I need to qualify your statement that “Judaism asserts that the latter name preceded the former whereas, I believe, Christianity claims the opposite.” I know me quoting Wikipedia will raise some eyebrows, but I think at least it sums the data well enough (from the article
Lucifer):
Origen (184/185 – 253/254) interpreted such Old Testament passages as being about manifestations of the Devil; but of course, writing in Greek, not Latin, he did not identify the Devil with the name “Lucifer”. Tertullian (c. 160 – c. 225), who wrote in Latin, also understood Isaiah 14:14 (“I will ascend above the tops of the clouds; I will make myself like the Most High”) as spoken by the Devil, but “Lucifer” is not among the numerous names and phrases he used to describe the Devil. Even at the time of the Latin writer Augustine of Hippo (354 – 430), “Lucifer” had not yet become a common name for the Devil.
Some time later, the metaphor of the morning star that Isaiah 14:12 applied to a king of Babylon gave rise to the general use of the Latin word for “morning star”, capitalized, as the original name of the Devil before his fall from grace, linking Isaiah 14:12 with Luke 10:18 (“I saw Satan fall like lightning from heaven”) and interpreting the passage in Isaiah as an allegory of Satan’s fall from heaven.
I’ll let you in on a secret. (Well, maybe it’s not so much a secret.) That popular story among us Christians about Satan/‘Lucifer’'s fall has more to do with John Milton’s
Paradise Lost than it has about the actual Scriptures.
In the Christian Scriptures, what you really have is a brief statement from Jesus about seeing Satan falling from heaven “like lightning” (Luke 10:18), John’s vision of the war in Heaven (Revelation 12:7-9), as well as typological/allegorical interpretations of certain Old Testament passages such as the Isaiah 14 passage or Ezekiel’s prophecy against the king of Tyre (28:11-19), likening him to a ‘covering cherub’ who was “on the holy mountain of God” (at least in the Hebrew text; the Septuagint instead seems to compare the king of Tyre to Adam instead). That’s it. All you can infer from those passages is the idea that Satan was thrown out of Heaven; if you add in the Isaiah passage, you might infer that the cause of the fall was maybe due to pride on Satan’s part.
Everything else you might hear (Satan’s original name being ‘Lucifer’, Michael getting his name because he
literally said, “Who is like God?” Lucifer/Satan’s defiant line: “Better to reign in Hell than serve in Heaven,” etc.) is more the product of centuries of pious Christian imagination and/or John Milton ‘filling in the blanks’. In other words, it’s more in the realm of legend/folklore/poetic license than actual doctrine. Nobody was there to witness the actual event of course, so I guess that can’t be helped.
In fact, the Catechism only lays out the barest essentials as to who and what the Devil is, and does not go into specifics. This pretty much sums up some of what we Catholics believe about Satan.
391 Behind the disobedient choice of our first parents lurks a seductive voice, opposed to God, which makes them fall into death out of envy. Scripture and the Church’s Tradition see in this being a fallen angel, called “Satan” or the “devil”. The Church teaches that Satan was at first a good angel, made by God: “The devil and the other demons were indeed created naturally good by God, but they became evil by their own doing.”
392 Scripture speaks of a sin of these angels. This “fall” consists in the free choice of these created spirits, who radically and irrevocably rejected God and his reign. We find a reflection of that rebellion in the tempter’s words to our first parents: “You will be like God.” The devil “has sinned from the beginning”; he is “a liar and the father of lies”.
