With over twenty volumes, the Nicene and Post-Nicene Fathers is a momentous achievement. Originally gathered by Philip Schaff, the Nicene and Post-Nicene Fathers is a collection of writings by classical and medieval Christian theologians. The purpose of such a collection is to make their writings readily available. The entire work is divided into two series. The first series focuses on two classical Christian theologians--St. Augustine and St. John Chrysostom. St. Augustine is one of the most influential and important Christian thinkers of all time. In addition to reprinting his most popular two works--the Confessions and the City of God--these volumes also contain other noteworthy and important works of St. Augustine, such as On the Holy Trinity, Christian Doctrine, and others. St. John Chrysostom was an eloquent speaker and well-loved Christian clergyman. St. John took a more literal interpretation of Scripture, and much of his work focused on practical aspects of Christianity, particularly what is now called social justice. He advocated for the poor, and challenged abuses of authority. The Nicene and Post-Nicene Fathers is comprehensive in scope, and provide keen translations of instructive and illuminating texts from some of the greatest theologians of the Christian church. These spiritually enlightening texts have aided Christians for over a thousand years, and remain instructive and fruitful even today!
