The Biological Basis of Homosexuality: A Christian Assessment

Abstract

Concurrent with an interest in the incidence and characterization of homosexuality has been an increased interest in the biological basis of such behavior. The present article reviews evidence in support of a biological basis of homosexuality in three interrelated categories—genetic evidence, the prenatal neurohormonal hypothesis, and neuroanatomical evidence. An attempt is made to not only review studies that are representative of experimental findings in each of these categories, but to critically assess the evidence in terms of experimental protocol. In an attempt to provide a Christian assessment of the biological evidence, three conclusions are drawn: (1) evidence for a biological basis of homosexuality is sufficient to warrant its acceptance; (2) the nature of the biological influence on homosexuality is predisposing not determining, thus providing the potential for change; and (3) acceptance of a biological basis of homosexuality in no manner changes the biblical condemnation or prohibition of such behavior. Finally, the need for the Christian church to reach out and minister to homosexual individuals is briefly discussed.
