HELIOTHEISM — [Noun] The worship of the Sun as a deity; the belief that the Sun is a god. From the combining form helio- (from Greek hēlios, "sun") and -theism (from Greek theos, "god"), meaning "belief in a god." Unlike henotheism, which elevates one deity among many, or a solar cult, which codifies specific rituals of veneration, heliotheism is the pure theological premise that the life-giving disc itself is divine. It is the Pharaoh’s unblinking gaze at the Aten’s disk, the Inca priest’s sacrifice at dawn, and the farmer’s instinctive turn toward the blinding, golden eye—a faith born not from abstraction, but from the daily, visceral proof of a power that grants life and imposes the final, absolute night.
