The City of God stands as Augustine's masterwork of theological defense and construction, written over thirteen years in response to accusations that Christianity brought ruin upon Rome. This first volume contains the first ten books of sustained refutation—demolishing pagan claims that traditional worship secured either temporal prosperity or eternal happiness—followed by the beginning of his positive vision in Books Eleven through Thirteen, where he traces the origin of two societal orders to the primordial division among the angels. What emerges is not merely an apology for Christianity but a philosophy of history that subordinate the fate of empires to the hidden providence of the one true God, whose sovereignty extends from creation through the fall to the final judgment.
The Christian hope surpasses anything the philosophers imagined. Plato’s best souls must undergo endless cycles of embodiment and disembodiment, forgetting and returning. Porphyry, ashamed of this doctrine in the Christian era, taught that purified souls escape all bodies forever—but he still required them to worship gods who remain embodied. The Christian promise is superior: the saints will rise in their own bodies, transformed so that neither corruption nor unwieldiness afflicts the flesh, neither grief nor trouble clouds their joy.
The resurrection body will surpass even Adam’s pre-fall body. Adam possessed an animal body—animated by a living soul but not yet quickened by the Spirit. He required food and the tree of life to sustain his existence and ward off death. The resurrection body will be spiritual—not converted into spirit, but perfectly subject to the spirit, free from all corruption and reluctance. It will not need food for sustenance, though it will retain the power to eat. Christ Himself ate after His resurrection, demonstrating that the spiritual body can still participate in such acts without needing them.
Augustine acknowledges that Paradise admits of allegorical interpretation. Some understand it as representing the life of the blessed, its rivers as the four virtues, its trees as useful knowledge, the tree of life as wisdom, and the tree of knowledge as the experience of transgression. These spiritual meanings may also point to the Church: Paradise as the Church, its rivers as the four Gospels, its fruit trees as the saints, the tree of life as Christ. Such allegories are profitable so long as they do not displace the historical truth that a real Paradise existed and real events occurred there.
The distinction between the animal body and the spiritual body rests on apostolic teaching. Paul states that the first Adam became a living soul, while the last Adam became a life-giving spirit. The animal body is animated by the soul; the spiritual body is quickened by the Spirit. Adam’s body, though not subject to death before sin, was still animal—it required sustenance and was preserved from decay only by access to the tree of life. The resurrection body will be inherently immortal, unable to die at all, transformed by the Spirit’s quickening power.
