Lucifer:

(Latin: lux, lucis, luce, luci, and lucu: “light”; fer, fero: “to bear, carry, support, lift, hold, take up”; these synthesize as “Bearer of Light”) Before Milton, Lucifer had never been a name of the devil. One of the early Popes of Rome bore that name, and there was even a Christian sect in the fourth century which was called the Luciferians. In Universal Gnosticism, Lucifer is the shadow of the Christ.
