Attributing the name Lucifer to Christianity is an age old misconception. The name itself derives from Latin, meaning 'light bearer' and it was another name used for the planet Venus in ancient times before the Common Era. In other words, the name was conjured not by the Christian mythology but a much earlier faith.

Ironically enough, there was a Bishop Lucifer in the 4th century AD.

It was only modern Christianity, not the Christian origins, which demonized the name, thus giving the name Lucifer its current associations.
