Augustine and the Hierarchy of Evil
How One Convert Permanently Changed the Church's Understanding of Satan
Few Christian thinkers have shaped the Church's understanding of evil more profoundly than Augustine of Hippo (354–430). His writings influenced medieval theology, informed the Protestant Reformers, and continue to shape Christian thought today. Yet one of his most significant contributions is often overlooked. Augustine fundamentally changed the way Christians understood the devil—not by minimizing the reality of evil, but by denying evil the status it constantly claimed for itself.
That achievement is remarkable because, before his conversion to Christianity, Augustine believed precisely the opposite.
For nearly a decade he was a devoted adherent of Manichaeism, a religion founded in the third century by the Persian teacher Mani. Manichaeism presented the universe as the battleground of two eternal and opposing principles: one wholly good and the other wholly evil. Light and darkness existed as independent realities locked in perpetual conflict. Matter itself was viewed as the prison of divine light, and human history unfolded as part of an ancient cosmic struggle whose outcome remained uncertain.
To Augustine, this worldview initially seemed persuasive. It accounted for the obvious presence of suffering, wickedness, and spiritual conflict without requiring God to bear responsibility for evil. The darkness of the world appeared too organized, too pervasive, and too destructive to be merely the corruption of something good. Evil seemed to possess its own existence, its own kingdom, and its own authority.
Christianity forced Augustine to reconsider everything.
As he immersed himself in Scripture, he became convinced that the biblical story simply would not allow evil to occupy such an exalted place. The greatest theological revolution of his life did not begin with demons or the devil. It began with Genesis.
The Revolution of Genesis
The opening chapter of Scripture became decisive for Augustine's understanding of reality.
Again and again the creation narrative declares that what God had made "was good" (Genesis 1:10, 12, 18, 21, 25, ESV), culminating in the affirmation that "God saw everything that he had made, and behold, it was very good" (Genesis 1:31, ESV). Augustine recognized that these repeated declarations carried profound implications. If everything that exists owes its existence to the Creator, and the Creator is wholly good, then evil cannot be another created substance existing alongside creation. Neither can it be an eternal principle rivaling God.
The alternatives were mutually exclusive.
Either evil was something God created—which Genesis denied—or it possessed an existence independent of God—which Scripture denied just as clearly.
Augustine therefore reframed the question itself. Rather than asking where evil originated as though it were a substance waiting to be discovered, he asked what kind of reality evil actually is.
His answer would shape Christian theology for centuries.
In the Enchiridion, Augustine asks, "For what is that which we call evil but the absence of good?"¹ Evil is therefore real, but its reality differs fundamentally from the reality of created things. It possesses no independent existence. Rather, it is the corruption, distortion, or deprivation of what God originally created good.
The distinction is subtle but revolutionary.
Disease is real, yet it is not another form of health existing alongside wellness. It is the corruption of a healthy body. Rot does not replace healthy wood with a different substance; it consumes wood that already exists. Darkness does not compete with light as an independent reality. It exists only where light is absent.
For Augustine, evil functions in precisely the same way.
It never creates.
It corrupts.
It never establishes an independent order of existence.
It disorders what God has already made.
Augustine had not merely offered a philosophical explanation. He had fundamentally reframed the Christian understanding of evil. Darkness remained terrifyingly real, but it could no longer be understood as an eternal kingdom standing alongside God. Evil was parasitic rather than original, corruptive rather than creative, and forever dependent upon the good it sought to destroy.
This insight also transformed Augustine's understanding of divine providence. In the same work he writes, "For the Almighty God... would never permit the existence of anything evil among His works, if He were not so omnipotent and good that He can bring good even out of evil."² Evil is therefore neither desired by God nor beyond His rule. Even rebellion unfolds within a creation that remains governed by its Creator.
A Creature, Not a Rival
This theological revolution inevitably reshaped Augustine's understanding of Satan.
The devil is neither a metaphor nor an illusion. Augustine regarded him as a genuine personal being whose rebellion had introduced profound disorder into God's creation. Yet Satan's reality did not require granting him independent sovereignty.
He remained a creature.
This point cannot be overstated because it distinguishes biblical Christianity from many religious systems before and after Augustine. The devil is not God's opposite. He is not the ruler of an independent kingdom equal in authority to heaven. His existence itself depends upon the God against whom he rebels.
In The City of God, Augustine argues that every created being possesses goodness simply by virtue of existing, because existence itself is a gift from God.³ Even the demons retain the existence, intelligence, and spiritual capacities originally bestowed upon them by their Creator. Their rebellion did not produce a new nature. It corrupted the good with which they had been created.
That distinction changes everything.
The devil cannot create life.
He cannot sustain existence.
He cannot originate truth.
He cannot establish a rival kingdom independent of God's providence.
Every capacity he possesses remains borrowed.
Every act of rebellion depends upon gifts he did not create and cannot preserve.
This understanding permanently altered Christian demonology. Satan remained dangerous because corruption is genuinely destructive. Sin wounds. Temptation deceives. Accusation discourages. Demonic opposition is neither imaginary nor insignificant. Yet none of these realities elevate evil into a second principle governing the universe.
The enemy is formidable.
He is never ultimate.
Ordered Loves and Disordered Hearts
Augustine extended this insight beyond demonology into the nature of human sin.
He believed that people rarely love evil simply because it is evil. More often, they love good things in the wrong order.
This became his famous doctrine of ordo amoris—the order of loves.
Family is good.
Work is good.
Beauty is good.
Pleasure is good.
Power can be good when exercised justly.
Sin emerges when these created goods are elevated above the Creator Himself. Idolatry is therefore not primarily the love of wicked things but the disordered love of good things.
The same pattern explains the rebellion of Satan.
Pride did not create something new within the devil. It corrupted what already existed. The highest of created beings turned inward upon himself, seeking the place that belongs to God alone. Love became disordered. Worship became self-exaltation. Rebellion emerged not through creation but through corruption.
For Augustine, this explains why evil so often appears persuasive. It rarely invents entirely new desires. Instead, it takes legitimate goods and invites human beings to pursue them apart from the God who gives them meaning.
Corruption, not creation, remains its defining characteristic.
Why Augustine Still Matters
Modern discussions of spiritual warfare often drift toward one of two opposite errors. Some dismiss the devil altogether, reducing evil to psychological, social, or political categories. Others speak of Satan in ways that unintentionally grant him an authority approaching God's own, portraying history as though two nearly equal kingdoms are locked in an uncertain struggle.
Augustine rejected both conclusions.
He took evil with complete seriousness because he understood how profoundly corruption could wound both individuals and societies. Yet he refused to exaggerate its authority. The devil remained dangerous, but never sovereign. Demons remained active, but never autonomous. Evil remained destructive, but never creative.
This perspective would become one of the defining assumptions of orthodox Christianity. Medieval theologians inherited it. The Reformers strengthened it. It continues to provide one of the Church's most important safeguards against both skepticism and fear.
Augustine's greatest contribution was not that he described evil more thoroughly than those who came before him. It was that he permanently denied evil the throne it constantly claims for itself. By grounding his theology in the opening chapters of Genesis, he reminded the Church that the biblical story begins not with darkness but with the goodness of God, and that every subsequent discussion of Satan must remain governed by that first and foundational truth. Evil is real, but it is never independent. The enemy is active, but he is never autonomous. The sovereignty of God remains the first word of Scripture—and, for Augustine, it also remains the last.
