As a Gnostic Luciferian I would like to weigh in on my beliefs on this.
Lucifer is the only icon of free will in Genesis. Submit is the closest to the actual meaning in this post, by using the word "Helel".
I'd like to share a few quotes from the writers I respect most on this issue.
Albert Pike, 33rd degree Freemason - “Lucifer the Son of the Morning! Is it he who bears the Light, and with its splendours intolerable blinds feeble sensual, or selfish souls? Doubt it not!"
And of course, Manly P Hall (died 1990, RIP), writes in his book:
"Lucifer represents the individual intellect and will which rebels against the domination of Nature and attempts to maintain itself contrary to natural impulse. Lucifer, in the form of Venus, is the morning star spoken of in Revelation, which is to be given to those who overcome the world."
A common misconception by Christians and Muslims alike is that they falsely claim Lucifer is Satan. Lucifer is not Satan.
Lucifer is the "Morning Star", aka Venus.
Revelation 22:16 - "I, Jesus, have sent my angel to give you this testimony for the churches. I am the Root and the Offspring of David, and the bright Morning Star."
Reading this, we realize that, just as Lucifer is known as the morning star, Jesus refers to himself as the Morning Star as well. To conclude, Manly P Hall (Freemason) writes, "Lucifer, in the form of Venus, is the morning star spoken of in Revelation, which is to be given to those who overcome the world."
"Hence, rest assured that Jesus and Lucifer are one and the same which will become clearly evident to those with an eye to see the true light amongst the darkness in which we live"
