The Christian theologians of late antiquity are referred to as the Fathers of the Church (Kilcullen- Robinson 2017: 6). The most influential of them in medieval Europe was Augustine; others included Ambrose, Cyprian, and Gregory (ibid). Many of the Fathers were influenced by the Platonism and Stoicism, as every educated person became acquainted with in the ancient world. Augustine, who was particularly influenced by Neoplatonism, especially by Plotinus, could be seen as a milestone on the path from The Fathers of the Church to early scholastics (ibid). Augustine’s major work, The City of God (De Civitate Dei) will be the object of focus under this title because it is a work whose influence is not limited to that of medieval political thought.
