LUCIFER Traditionally, Lucifer (English pronunciation: /ˈluËsɪfÉ™r, ljuËsɪfÉ™r/) is a name that in English generally refers to the devil before being cast from heaven, although this is not the original meaning of the term. In Latin, from which the English word is derived, Lucifer means "light-bearer" (from the words lucem ferre). It was the name given to the dawn appearance of the planet Venus, which heralds daylight. For this meaning, English generally uses the names "Morning Star" or "Day Star", and rarely "Lucifer".
Use of the name "Lucifer" for the devil stems from a particular interpretation of Isaiah 14:3-20, a passage that does not speak of any fallen angel but of the defeat of a particular Babylonian King, to whom it gives a title that refers to what in English is called the Day Star or Morning Star (in Latin, lucifer).[2] In 2 Peter 1:19 and elsewhere, the same Latin word lucifer is used to refer to the Morning Star, with no relation to the devil. It is only in post-New Testament times that the Latin word Lucifer was used as a name for the devil, both in religious writing and in fiction, especially when referring to him prior to his fall from Heaven.
