A new survey by the Pew Research Center highlights major differences between Europe and the USA not only in the level of religious affiliation but in what exactly religious affiliation means.
In the USA people who identify as non-practising Christian, i.e., people who self-identify as 'Christians' but who don't go to church regularly or, in some instanced, don't believe in God, are far more likely to believe in God with absolute certainty (27%) than Europeans (3%); they are ten times more likely to pray daily (20% and 2% respectively), to attend religious services at least monthly (9% and 1% respectively) and think religion is important in their lives (13% and 1% respectively).
In Europe 'Christian' is much more a cultural identified rather than a statement of religious belief, with 16% calling themselves Christian but not actually believing in any god and only 24% believing in the god of the Bible. The remaining 51% believe in a 'higher power' of some sort but not the Biblical god. In effect, 16% of European 'Christians' are actually Atheists and have no problem describing themselves as Christian Atheists, just as non-religious Jews will identify themselves as Jewish Atheists.
Hidden in that statistic is the fact that 67% of European 'Christians' don't believe in the Bible, or at least the god described in it, and implicitly reject the Bible as the divine word of the Christian god. Curiously, 2% of church-attending Christians don't believe in any god. Presumably they attend regularly with someone who does believe in the Biblical God.
