Book excerpt: Mainstream Christian theology has valued the integrity of the body and the goodness of God reflected in creation. However, it has also asserted the complementarity of "normal" male and female physiology. Sex and Uncertainty in the Body of Christ offers the first systematic theology of the intersexed body. The book analyzes the theological implications of physical intersex conditions and their medical treatment. The medical assumption of what constitutes male and female bodies is shown to raise essential questions about the meaning of incarnation and bodiliness. The book argues for a theology that speaks to stigmatized and marginal bodies, examining the impact of such a theology on sex, marriage, sexuality, perfection, healing, and the resurrected body.
