What is the society of the damned? What relationship does God have with hell? Is hell simply a place of eternal torment or a more complex reality? In this culmination of his theological thought, José Antonio Fortea dismantles simplistic conceptions by revealing the social structure of hell, the dynamics between demons and the damned, the nature of hellish suffering and—surprisingly—the “laws” that the Creator has established to make that state habitable. An essay that challenges our traditional understanding of eternal damnation. With theological rigor and intellectual courage, Fortea dissects the infernal state not as a mere place of punishment, but as a complex reality rooted in the understanding of divine nature. The author presents us with a vision that challenges traditional conceptions, explaining how hell exists within the divine plan of love, not as a mere consequence of justice. This work invites us to understand that, as Fortea himself says, “eternal damnation is understood more fully by delving deeper into the Trinitarian life of the Creator.” In this way, his analysis starts from the Holy Trinity and gradually descends into the mystery of hell, establishing unexpected connections between divine love and the existence of the underworld. The Laws of Hell completes the theological worldview that the author has developed through titles such as Treatise on Lost Souls and History of the Angelic World, although it can be read independently. With clear and precise prose, Fortea guides us through the history and future of hell, the link between time and eternity in damnation, and the metaphysical foundations that sustain this state of eternal existence without God. By the end of this book, readers will not only have explored the abysses of the afterlife, but will also have contemplated, paradoxically, the luminous face of divine mercy through the enigma of its justice.
