Lucifer's Fall: Transformation of Divine Identity

Lucifer's fall, accompanied by the loss of his original divine name (which, as noted, meant "Lightbringer"), symbolizes not merely a physical transition into material existence, but above all a transformation of his essence and function in the cosmic order. Originally, Lucifer was created as the embodiment of supreme beauty, wisdom, and power, as confirmed by the description:
"Among them was an angel, created as the most beautiful, the wisest, the strongest. He was given a wondrous name – Lightbringer (Latin "Lucifer", Slavic "Dennitsa")." (source: link txt)

The fall—when he resolved to rebel against God—shattered this harmony and fundamentally altered his inner nature. The loss of the name serves as a metaphor for the loss of that pure, exalted identity associated with his former nature. Having acquired the traits of a rebel and the embodiment of pride, he ceases to be what he was once known as and becomes the bearer of qualities that oppose the idea of divine wholeness. This is also confirmed in the description of the moment of the fall:
"The Fall of Lucifer. Everything was in harmony until the day when Lucifer decided to rebel against God." (source: link txt)

Regarding the question of who took the place of the lost identity, no explicit successor in the former concept of the guardian angel or bearer of light among the angels is designated. The role he performed as the guardian of the Earth and the personification of the first light ceased to exist in its previous form—in his fall, the "Great Drama" unfolded, where a new cosmic dynamic was defined by the conflict between supreme will and pride. It was Lucifer's rebellion that initiated the eternal war between good and evil. Thus, although Lucifer once held the position of guardian angel ("Lucifer was the guardian angel of the entire Earth, of the whole human world." – source: link txt), his fall forced the world to reconsider its values and priorities; it is through the emergence of human sin and the awareness of the opposition between grace and pride that a new structure of being unfolded.

In this way, the loss of the name—and, accordingly, the original identity—signifies not so much the appearance of a specific replacement as it does a radical change in role, resulting in the old order giving way to an eternal struggle between the yearning for divine closeness and the desire for self-deification, with which his fallen image is associated.
