Nicene and Post-Nicene Fathers: Series I/Volume II/City of God/Book XIX
Book XIX.
————————————
Argument—In this book the end of the two cities, the earthly and the heavenly, is discussed. Augustin reviews the opinions of the philosophers regarding the supreme good, and their vain efforts to make for themselves a happiness in this life; and, while he refutes these, he takes occasion to show what the peace and happiness belonging to the heavenly city, or the people of Christ, are both now and hereafter.
