there is no title. there is no lucifer. it is simply a hebrew word translated into a latin word and given life only in the imaginings of those who have fallen prey to deception. now in roman times, lucifer was the name of the planet venus and all the attendant mythology that goes with that. again, no bearing on this passage of scripture in isaiah. why the translators of the king james version chose to use this latin word is probably due to the vulgate tradition. it should read from the hebrew to english 'bright star, son of the morning'. make of that what you will.
