The City of God

Saint Augustine's work delves into Christian philosophy, defending the faith against accusations of causing Rome's decline. It presents a vision of citizenship that transcends earthly concerns, emphasizing a community focused on God and grace. Augustine contrasts the earthly city with the heavenly one, analyzing the nature of good and evil while engaging with pagan beliefs and classical philosophy. This foundational text not only shaped Augustine's contemporaries but also solidified his role as a key figure in Catholicism, influencing Christian thought for centuries.
