Dualism is a worldview that divides reality into two basic and often opposing principles, such as spirit and matter or good and evil. In Bible study, it is usually a philosophical or religious category rather than a doctrine Scripture teaches.
Dualism is a broad worldview that explains reality through two fundamental principles, such as spirit versus matter or good versus evil.
Dualism is a broad term for views that explain the world through two basic realities, often set in contrast or conflict. In religion and philosophy, this may mean spirit versus matter, mind versus body, or good versus evil. A Christian dictionary entry must handle the term carefully because Scripture does make real distinctions—such as Creator and creation, heaven and earth, flesh and Spirit, righteousness and wickedness—yet it does not present the universe as ruled by two equal and independent powers. God alone is sovereign, evil is rebellious and temporary rather than ultimate, and the material creation is God's good handiwork, though now fallen. Because the word covers several different systems and can be used loosely, this entry is best treated as a background theological term with careful scope limits.
The Bible recognizes real oppositions: light and darkness, truth and falsehood, flesh and Spirit, righteousness and lawlessness. Yet these contrasts do not imply two equal ultimate powers. Genesis presents one sovereign Creator who made all things good, and later Scripture insists that the Lord alone is God. New Testament teaching likewise affirms Christ’s supremacy over all creation and all hostile powers.
In the history of ideas, dualism appears in several forms. Some philosophical systems contrast spirit and matter, while some religious systems describe good and evil as opposing forces. Ancient and late-ancient versions of dualism often pressed beyond biblical categories and tended to devalue the material world or divide reality into competing ultimate principles.
Second Temple Jewish thought strongly resisted any view that placed God in rivalry with another eternal power. Jewish Scripture upheld one Creator, one sovereign Lord, and a good creation. At the same time, Jewish apocalyptic writings and later Jewish reflection could speak vividly about conflict between righteousness and wickedness, God’s kingdom and evil powers, without surrendering to an ultimate metaphysical dualism.
“Dualism” is a modern theological and philosophical label, not a biblical term. Scripture’s own vocabulary more often uses contrasts such as flesh/Spirit, light/darkness, truth/falsehood, and good/evil.
Theologically, dualism matters because it helps distinguish biblical contrast from unbiblical cosmology. Scripture affirms moral and spiritual conflict, but it rejects any system in which evil is coequal with God or matter is inherently evil. The doctrine of creation, the fall, providence, and redemption all depend on God’s absolute supremacy.
In philosophy, dualism can refer to a split between two fundamental substances, principles, or realms. That category may be useful descriptively, but Christian theology must test it against Scripture. The Bible does not teach that spirit is good and matter is bad by nature; instead, it teaches that God created material reality, sin has corrupted creation, and God will redeem and renew it.
Do not import later Gnostic, Manichaean, or similarly dualistic ideas into Scripture. Also avoid flattening biblical contrasts into mere metaphor: the Bible truly distinguishes God from creation and righteousness from evil. The key question is whether a system makes these distinctions under God’s sovereignty or turns them into rival ultimate principles.
The term is used in several ways: ontological dualism contrasts two kinds of being or substance; cosmological dualism posits competing powers in the universe; moral dualism treats good and evil as opposing forces. Biblical theology acknowledges real dualities of contrast but rejects ultimate dualism.
Affirm that God alone is eternal, uncreated, sovereign, and good. Affirm that creation, including matter, is good as created by God. Reject any view that makes evil an equal eternal principle, denies providence, or treats the physical world as inherently evil. Distinguish biblical tension from philosophical speculation.
The term helps Christians interpret false spiritual systems, avoid body-denying spirituality, and appreciate the Bible’s whole-world redemption. It also warns against reducing the Christian life to a battle between equal cosmic forces rather than obedience under God’s authority.
