Augustine's monumental work is inaccessible to most readers, as the fundamental ideas can easily be lost amidst the abundance of material. Therefore, this selection aims to provide a factual overview of the entire work that aligns with its internal logic. Augustine's overall effort is to depict the seriousness of the eternal decision in the two states, without Manichaeanly splitting the unity of creation. The "City of God" is the first and perhaps never surpassed theology of history, which presents not only the historical sequence but also the inner historicity of humanity and the world.
