From the Greek philosopher Plato, we have the Platonist tradition. From the Greek philosopher Aristotle, we have the Aristotelian tradition. The Christian philosopher-theologian Augustine drew from the works of Plato and Neoplatonism when writing his own works like Confessions and City of God. On the other hand, the Christian philosopher-theologian Thomas Aquinas drew from the works of Aristotle when writing such works as Summa Contra Gentiles (A Summary of Arguments Against the Disbelievers) and Summa Theologica (A Summary of Theology). Therefore, in order to best read and understand the Christian philosopher-theologians Augustine and Thomas Aquinas, it is important to read and understand the Greek philosophers Plato and Aristotle.
