Those who take the tradition of Christian sexual ethics seriously may occasionally wonder whether recent approaches actually help Christians to love others as God has loved them. Michael Haretwig takes both Catholic and Protestant ethical traditon seriously. However he recognizes how the approach of the last several centuries actually inhibits or even cripples Christians' ability to love intimately. He examines the tradition critically, develops a new model and applies that model to the situation in which we find ourselves at the beginning of this century. As a gay man Dr. Hartwig pays more attention to how this paradigm applies to gays and lesbians than others might. However he also applies it to heterosexuals and to people with disabilities with equally challenging and nourishing results. His scholarship is so rigorous that it will be difficult for others to ignore his work. Dr. Hartwig may indeed be providing the paradigm of Christian sexual ethics that will become the norm for the 21st century. Well worth the high price.
