This lecture critically examines the posthuman project of perfecting the human species from the standpoint of Christian theology. Posthumanists believe that through the employment of various technologies human beings can be transformed into a superior species. The promise of this project is that human performance will be greatly enhanced, and longevity will be significantly extended perhaps culminating in virtual immortality. The peril of the posthuman project is that such optimism may actually disguise a death-wish for the human species.This potential peril is derived from false religious precepts upon which posthumanism is based. Posthumanists believe, either implicitly or explicitly, that finitude and mortality represent the dire plight of the human condition. In response, posthumanism offers the ultimate salvation of virtual immortality that is achieved through the mastery and of nature and eventual perfection of human nature. The principal philosophical and religious strands of this salvific promise entail a combination of nihilism, Pelagianism, and Manicheism. These strands represent, respectively, a corruption of Christian belief: the will to power displaces obedient conformity to God’s will; the will to perfection displaces God’s gift of grace; and a hatred of the body displaces finitude as God’s blessing.The principal questions that divide posthumanists and Christians are those of anthropology and eschatology: What does it mean to be human? and What is the destiny of the human species? The centerpiece of a Christian theological reply to these questions is that both anthropology and eschatology is Christology. To know what it means to be human and what the destiny of the human species entails requires that we look to Jesus Christ. Specifically we look to the Incarnation as the affirmation of creaturely finitude and mortality; to the resurrection of Jesus Christ from the dead as the vindication of created order; and to Christ’s exaltation as the destiny of eternal fellowship with God as opposed to immortality. The lecture concludes by summarizing the difference between the posthuman project’s desperate search for endless time, and the Christian life as preparation for eternal fellowship with God.
