Samuel Gregg writes in this commentary, that when Merkel said the above in 2010, she added that “the issue was not “too much Islam” but “too little Christianity.””

Gregg continues: “We have too few discussions about the Christian view of mankind,” Merkel claimed in a recent speech. She then stressed that Germany needs to reflect more upon “the values that guide us, about our Judeo-Christian tradition.” It was one way, Merkel maintained, of bringing “about cohesion in our society.”

Gregg, who at the time of writing was Research Director at the Acton Institute, comments:

Yet it is hardly a secret that the Judeo-Christian heritage sits very loosely on many European societies. We find this in a type of secular-fundamentalism—exemplified by Spain’s current Socialist government—that has become fashionable among sections of the European Left. But the ambiguity also manifests itself in the persistence of historical legends that diminish, distort, and denigrate Christianity’s contributions to European civilization.

A good example is the mythology of the so-called “Dark Ages” that permeates popular and elite discussion of European history. Most of the moral, political, and legal foundations of modern market economies, for instance, were established in Europe well before the sixteenth century. Likewise the scientific method was born in the Middle Ages. Medieval thinkers such as Albertus Magnus made crucial contributions to the development of the natural sciences. Yet despite these facts, many persist in claiming that market economies are essentially a post-Enlightenment phenomenon, or that Christianity is essentially “anti-science.”

But the problem is not only with secular opinion. Since the 1950s, many European Christians have gradually reduced their Christian faith to a vacuous humanitarianism worthy of the best EU-funded NGO. One difficulty with “liberal Christianity” (or whatever’s left of it) is that it isn’t especially interested in affirming any Christian values that go beyond sentimental platitudes about tolerance and equality which are routinely emptied of any specific Christian content. It’s goodbye Thomas Aquinas, hello John Rawls.

This makes it even more ironic that increasing numbers of secular European thinkers believe Europe can only reinvigorate its distinct identity and values through reengaging its Judeo-Christian heritage. This is certainly the conclusion of one of Germany’s most prominent intellectuals, Jürgen Habermas.

A self-described “methodological atheist,” Habermas has been insisting for some time that Europe no longer has the luxury of wallowing in historical denial. As Habermas wrote in his 2006 book, A Time of Transitions: “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. We continue to nourish ourselves from this source. Everything else is postmodern chatter.”

It follows that any serious discussion of Europe’s Christian values in the context of contemporary immigration and identity debates will require many Europeans to go beyond their often-truncated understandings of European history and Christianity. There’s something paradoxical about this being facilitated by the increasing numbers of Muslims living in Europe. But such an engagement is arguably being made even more urgent by the economic reality that Europe will need even more immigrants if its present demographic winter persists for any significant period of time.

What Chancellor Merkel herself understands by “the Christian view of mankind” was not clear from her remarks. Nor is it evident that particular Christian ideas are always compatible with some Muslim positions. Despite the interfaith babble to the contrary, there are some fundamental theological differences between Christianity and Islam, many of which have implications for subjects ranging from religious liberty to the nature of the state. Merkel, however, is undoubtedly correct to insist that any discussion of immigration in Europe should involve Europeans worrying a little less about Islam and paying far more attention to knowing the truth about their own heritage and Christianity’s place in it.

The truth doesn’t just set us free. There’s no future without it.
