Catholic sex ethics is “still” as fully reasonable today as it was when St Paul expounded it—and identified prostitution and same-sex sex acts as obviously or visibly far out of line with it—as the sort of thing that people would lose their sound judgment about if and only if they or their society were blind to or careless about the omnipresent, invisible reality of divine causation ex nihilo, divine providence, and the possibility of a divinely willed human destiny beyond death. The natural law understanding of human fulfillment is inherently intelligible without adverting to that “theistic” framework. But when reason closes itself off against the real framework as a true whole—in thought decapitating it—other distortions of understanding and judgment will ensue, especially in reason’s practical domain, where desire and satisfaction provide every incentive to rationalization of misjudgment.
