Raguel is the archangel of justice, fairness, harmony, vengeance, and redemption. Raguel is one of the seven angels whose role is to watch. His function is to take vengeance on the world of the luminaries who have transgressed God's laws.
Raguel's duties have remained the same across Jewish and Christian traditions. Much like a sheriff or constable, Raguel's purpose has always been to keep fallen angels and demons in check, delivering judgment upon any that over-step their boundaries. He has been known to destroy wicked spirits and cast fallen angels into Hell.
