Evangelical pronouncements on the role of government are often contradictory. Sometimes when attacking government measures they dislike, evangelical voices use libertarian arguments that forbid almost all government programs to help the poor. (“Helping the poor is a task for individuals and churches, not the government. Government should provide a legal framework, fair courts, and police protection but then leave almost everything else to the free choice of individuals.”) But when the issue changes from the poor to the family, the definition of marriage, abortion, or pornography, the same people quickly abandon libertarian arguments that maximize individual freedom. Instead they push vigorously for legislation that involves substantial government restriction of individual choices. It is possible that there are valid intellectual arguments for adopting libertarian arguments in the first case and nonlibertarian arguments in the second. But a careful argument would have to be made. Without such argument, flipping from libertarian to nonlibertarian arguments looks confused and superficial.
