Christians in Western Europe

Our next lecture will discuss the process of secularization, a process that seems to be furthest along in Western Europe.  But just what exactly does religion look like in Western Europe?  Earlier today the Pew Research Center released a report titled "Being Christian in Western Europe" (complete report in pdf here) that answers exactly that question.  It's one sentence summary is:

The majority of Europe’s Christians are non-practicing, but they differ from religiously unaffiliated people in their views on God, attitudes toward Muslims and immigrants, and opinions about religion’s role in society.

Put differently, although church attendance rates are low, being Christian is still a meaningful notion in Europe as it does correlate with religious, political, and cultural views.

The report is long, but do read the overview page to find answers to these questions.

1. What country in Western Europe has the highest rate of church attendance?
2. Which is larger: the number of non-practicing Christians or the number of unaffiliated?
3. Who are more likely to express nationalist views:  non-practicing Christians or church-attending Christians?
4. What percent of church-attending Christians favor legal gay marriage?
5. Those that report "none" for their religious affiliation might still believe in God or a higher power.  For which Western European countries, is the rate of agnostic or atheists among the "nones" the highest?
