Lucifer is related to Light. Gnosticism came after Christianity as a heresy.
“Lucifer is related to Light.”
He was called the light-bearer - son of the dawn.
From the Judeo-Christian standpoint, the taking of the fruit by Eve and Adam at the serpent’s behest was shameful, a transgression of Yahweh’s commandment. From the Greek standpoint, however, the taking of the fruit was a triumphant and liberating act which brought to mankind the serpent’s enlightenment. To the Greeks, the serpent freed mankind from bondage to an oppressive God, and was therefore a saviour and illuminator of our race. The Greeks worshipped Zeus as both saviour and illuminator; they called him Zeus Phanaios which means one who appears as light and brings light. The light that he brought to the ancient Greeks was the serpent’s light that he received when he ate the fruit from the serpent’s tree.
