THE RISE OF CHRISTIANITY 45
To enjoy a thing means to embrace it with love for its own sake; but to use a
thing means to put it to work in order to obtain something else that is loved
. . . Imagine that we are a pair of travellers who are unable to live happily
except in our own home; we are miserable in our wandering and want noth-
ing more than to put an end to it and return to our native land. We need
various types of land and sea-transport to help us reach home. But now imag-
ine that the homeward journey itself delights us—the amenities of the trip,
the movement of our vehicles. We begin to enjoy those things which we are
using. If this were to happen, we would not wish to end our journey quite
so quickly and we would be trapped in a perverse pleasure that alienates us
from the very home that is the source of our happiness. That is what mortal
life is like; we are wanderers separated from God, and if we desire to return
to our homeland [i.e., to God] we ought to use this world we live in, but not
enjoy it.
For Augustine the journey home to God is the central point of life. The Fall of
Man in the Garden of Eden left a permanent stain of sin upon us, however, one
that was not removed until God Himself took human form in the person of Jesus
and made our salvation possible. By living unselfishly and piously we can hope
to make it home, but there is no guarantee of our success. To Augustine, nobody
“deserves” salvation—that is, no one can claim to be worthy of spending eternity
in God’s presence—and consequently only those who have received divine grace
will receive that greatest of gifts. Thus, to Augustine, humans have free will to
choose good or evil, but God too is free to bestow His grace wherever He wishes.
Our duty is to do our best, live rightly, and hope things will turn out—but we
can never be sure of our salvation.
Augustine’s greatest work was the massive treatise called The City of God.
Written over the course of thirteen years, it provided a Christian philosophy of
history—a way of interpreting the story of human life—that offered a radical new
vision. The predominant classical notion of history regarded it as essentially cir-
cular: Life progressed in an endless series of cycles that pointed to no particular
end and served no particular purpose. Although a few pagan cults had a concep-
tion of an afterlife, most of these were amoralized shadowy worlds to which all
people went regardless of their beliefs or actions on earth; the pagan gods thus
had no “divine plan,” and the main thrust of their religions was to enforce proper
behavior in this life without regard to any theoretical “next” life. Augustine op-
posed this view with a linear model of history that begins with God’s unique act
of creation, moves through God’s renewal of the world with the Incarnation of
Christ, and culminates in Christ’s Second Coming and the end of the world. His-
tory is a story with a beginning, a middle, and an end. In this way, human life is
ennobled with a purpose. We have been placed here for a reason, which is to
manifest the glory of God and to work toward our salvation. Augustine’s scheme
thereby places an intrinsic value on the experiences of every human individual.
What matters in history, therefore, is not the fate of kingdoms and empires, eco-
nomic systems, and social structures, but rather the spiritual and moral develop-
ment of every individual human from the highest emperor to the lowest slave.
But while history progresses to a specific, story-ending Day of Judgment, Au-
gustine warns, we must not waste our energies in trying to determine when that
day will arrive. From the time of Jesus’ crucifixion, many Christians had taken
literally his teaching that the kingdom of God was fast approaching, and they
effectively exiled themselves from society in order to prepare for the coming apoc-
alypse. Such expectations survived throughout the Middle Ages (and are still with
us), but Augustine argued forcefully that to speculate about the end of the world
