Lucifer was originally created as one of the most beautiful and powerful angels in Heaven. He was known as a cherub, a high-ranking angelic being. Cherubim are often depicted as guardians of God’s glory and are associated with the protection of sacred spaces.
Lucifer’s role was significant, and he held a position of great honor. However, his pride led to his downfall. He desired to be equal to or greater than God, which resulted in his rebellion and subsequent fall from grace. This event is often referred to as the Fall of Lucifer, after which he became known as Satan, the adversary.
In summary, Lucifer was a cherub, a high-ranking angel, before his rebellion and fall from Heaven.
