About Satan
Satan is a being whose name means "adversary" or "accuser" in Hebrew. In the Old Testament, he serves as an angel under God, tasked with testing humans, and is not explicitly described as a "fallen angel."
From the New Testament onward, he came to be called the "prince of evil," "god of this world," "ancient serpent," and his image as the king of demons grew stronger. However, Satan and Lucifer are originally separate entities.
Lucifer means "light-bringer" and refers to a beautiful, high-ranking angel (the morning star) before his fall. Satan, on the other hand, was a concept or role name meaning "adversary."
Through medieval Christian lore and literature, the two figures became fused and identified with each other, and in modern times they are often treated as virtually the same being.
A disruptor of order, a tempter of humanity—the "eternal adversary"—that is the essence of Satan in mythology.
