Book XIX: The Ends of the Two Cities explained

Augustine discusses the ultimate ends of the earthly and heavenly cities, contrasting the vain attempts of philosophers to achieve happiness in this life with the Christian hope of eternal blessedness.

What happens

Augustine discusses the ultimate ends of the earthly and heavenly cities, contrasting the vain attempts of philosophers to achieve happiness in this life with the Christian hope of eternal blessedness. He reviews Varro's classification of 288 possible philosophical sects regarding the supreme good, refutes their errors, and explains that the true supreme good is eternal life, while the supreme evil is eternal death. The heavenly city, while on pilgrimage, uses earthly peace but directs all toward the peace of heaven, living by faith and not by sight.

    Augustine asserts that the ultimate good is everlasting life, the ultimate evil is everlasting death, and right living is necessary to gain the one and avoid the other.

    This summarizes the Christian position on the supreme good and evil, contrasting with philosophical views.

  • The corruptible body weigheth down the soul, and the earthly tabernacle presseth down the mind that museth upon many things.

    The physical body, being subject to decay, burdens the soul and hinders the mind from contemplating truth.

    Augustine cites Wisdom 9:15 to illustrate the limitations of human knowledge in this life.

  • It is a matter of no moment in the city of God whether he who adopts the faith that brings men to God adopts it in one dress and manner of life or another, so long only as he lives in conformity with the commandments of God.

    External habits and lifestyle choices are irrelevant to the heavenly city as long as one obeys God's commandments.

    Augustine dismisses Varro's distinctions based on dress and mode of life, emphasizing inner faith and obedience.
