Ironically, after centuries of rebelling against religious authority, the coming of Islam is also reviving political issues most thought extinct in Europe, including debates about the limits of freedom of speech, freedom of religion, and the right to proselytize. And in all these areas, controversies that originate in a Muslim context inexorably expand or limit the rights of Christians, too. If Muslim preachers who denounce gays must be silenced, then so must charismatic Christians. At the same time, any laws that limit blasphemous assaults on the image of Mohammed must take account of the sensibilities of those who venerate Jesus.
The result has been a rediscovery of the continent’s Christian roots, even among those who have long disregarded it, and a renewed sense of European cultural Christianity. Jürgen Habermas, a veteran leftist German philosopher stunned his admirers not long ago by proclaiming, “Christianity, and nothing else, is the ultimate foundation of liberty, conscience, human rights, and democracy, the benchmarks of Western civilization. To this day, we have no other options [than Christianity]. We continue to nourish ourselves from this source. Everything else is postmodern chatter.” Europe may be confronting the dilemmas of a truly multifaith society, but with Christianity poised for a comeback, it is hardly on the verge of becoming an Islamic colony.
