But that project has failed, at least for now. In Texas, authorities have decided to side with science, not theology, in a dispute over the teaching of evolution. The terrible economic times have not led to an increase in church attendance. In Iowa last Friday, the state Supreme Court ruled against a ban on same-sex marriage, a defeat for religious conservatives. Such evidence is what has believers fretting about the possibility of an age dominated by a newly muscular secularism. "The moral teachings of Christianity have exerted an incalculable influence on Western civilization," Mohler says. "As those moral teachings fade into cultural memory, a secularized morality takes their place. Once Christianity is abandoned by a significant portion of the population, the moral landscape necessarily changes. For the better part of the 20th century, the nations of Western Europe led the way in the abandonment of Christian commitments. Christian moral reflexes and moral principles gave way to the loosening grip of a Christian memory. Now even that Christian memory is absent from the lives of millions."
