The separation of the soul from the body, a concept known as dualism, stems largely from Greek philosophers Socrates, Plato, Aristotle and the Stoics. Others since the Age of Enlightenment have defined humanity as only a cog in the universal cosmic machine. Unlike dualism, this view does not present the soul as immortal, but neither does it offer hope, since humans exist only in a machine-like universe driven by involuntary forces. JTL7 3.8
Both views are a denial of the biblical account of the origin of death, and cast doubt on the biblical teachings regarding the resurrection, the final punishment of the wicked, and the reward of heaven for the righteous. Dualism also impacts what we believe about our present life, particularly fostering negative views of the body in contrast with the positive role of the soul. In the dualistic theory, our redemption through Christ becomes merely an internal experience of the soul as opposed to a complete transformation of the whole person. JTL7 3.9
Many belief systems are derived from anthropological dualism. Consider the intercessory roles of Mary and the saints, or popular beliefs about paradise, purgatory, hell—all unsupported by biblical teachings regarding mortality. Since Plato considered material components of earth to be evil, the Christian’s hope of ultimate restoration of creation and its creatures (Romans 8:19-23) is reduced to some sort of eternal, ethereal contemplation in a spiritualized heavenly state. In contrast, the Bible’s emphasis on our need to act as God’s steward of our whole person impacts our response to today’s challenges such as war, racism, poverty and economic imbalance. JTL7 4.1
