This essay defends generic, holistic substance dualism—the claim that the human person is an integrated compound of an immaterial soul and a material body—against both contemporary secular physicalism and a post-biblical Hellenistic dualism that devalues physical embodiment.

(2005), contemporary philosophy of mind, and Walter C. Kaiser Jr.'s promise-plan of God (2008), it argues that physicalist models struggle to account for personal identity across time, the unity of consciousness, libertarian agency, and epistemological reliability. Recovering the Hebraic cognitive environment of Genesis 1–2, the essay treats the

Contemporary academic and popular culture is marked by a deep crisis concerning human identity. Influenced by scientific naturalism and eliminative materialism, one dominant intellectual paradigm reduces the human person to a neurobiological mechanism, treating self-consciousness, intentionality, and moral agency as epiphenomena of physical brain states (Churchland, 1988; Dennett, 1991; Kim, 1998). Under that reductionist frame, human dignity easily becomes contingent upon exercisable cognitive performance, exposing bioethics to utilitarian exploitation (Singer, 1993; Fletcher, 1979). A parallel piety, shaped by post-biblical Hellenistic dualism, bifurcates matter and spirit, reducing salvation to the escape of an immortal soul from a disposable physical prison (Wright, 2003).

What This Study Explores

Promise-Plan Theology

Does Christian Theology Require an Immaterial Soul?

A Christian account of the person need not choose between reductive physicalism and a body-denying Platonism. Holistic substance dualism understands the human being as an integrated union of an immaterial soul and a material body. The soul grounds persistent personal identity, first-person consciousness, rational agency, and moral responsibility, while the body is the indispensable means through which embodied vocation is exercised.

The soul’s ability to persist in an intermediate state does not make disembodied existence the Christian goal. Scripture directs hope toward bodily resurrection and renewed creation. The model therefore preserves continuity of the person through death while affirming that complete human life is embodied, relational, vocational, and ultimately restored through Messiah’s resurrection.

Key Claims

  • Brain states and mental states are not obviously identical. Thoughts possess intentionality, truth-value, and first-person qualities that physical descriptions do not capture.
  • Personal identity persists through physical change. The continuing self cannot be reduced simply to the replacement and rearrangement of bodily matter.
  • The imago Dei is an endowed identity. Human worth rests on divine designation, not on currently exercisable intelligence, independence, or productivity.
  • Intermediate survival is provisional. Biblical texts allow conscious existence after bodily death while keeping resurrection—not disembodiment—as the final hope.
  • Resurrection reunites person and body. First Corinthians 15 presents transformed embodiment as continuity and renewal rather than replacement by an unrelated replica.

Interpretive Context

The study develops Paul Copan’s critique of physicalism alongside John Cooper’s holistic dualism, Joshua Farris’s theological anthropology, and contemporary philosophy of mind. It also states Christian physicalist alternatives fairly and tests them against identity, consciousness, intermediate-state texts, and Christology.

Genesis 1–2 locates human identity within cosmic-temple vocation, while the promise-plan moves through new-heart and Spirit promises to Messiah’s resurrection and Revelation’s renewed creation. This framework refuses both materialist reduction and the Hellenistic devaluation of the body.
