THIS WE DO KNOW, DO YOU?
Let us first consider Isaiah 14:4-16, and in so considering note that it is plainly stated that this prophetic proverb, is a proverb. An illustrative story, or maxim used to illustrate something. Proverbs often utilize hyperbole, simile, euphemism, and many other tools of language to embellish and illustrate the matter and purpose of the subject of the proverb. A proverb is not a literal telling of something but rather an illustrative explanation. To appreciate this point allow me to ask; Do yo really believe that fir and cedar trees rejoice and talk as is written in verse eight? Are you really that much of a literalist?
The second thing to note is that the subject of this proverb is the king of Babylon. Emphasized in the sixteenth verse where the question is asked, "Is this the man that made the earth to tremble?" The subject of this proverb was a man, the man was the king of Babylon. The subject was not a heavenly angel inciting rebellion in heaven.
As concerning the Latin or Roman name Lucifer it must be noted that in the Hebrew text and language no such name existed. This naming of the king of Babylon was added centuries after the church fell away. It was initially inserted into the Latin Vulgate. The title "son of the morning" was nothing more than Hebrew satirical sarcasm, scorning the self exalted king of Babylon at his impending downfall.
The idea that this scripture has a duel meaning one being the natural king of Babylon and the other in reference to some contrived fallen arch angel is speculative at best and without evidence.
