In Europe there has been a general move away from religious observance and belief in Christian teachings and a move towards secularism. The "secularization of society", attributed to the time of the Enlightenment and its following years, is largely responsible for the spread of secularism. For example, the Gallup International Millennium Survey [https://web.archive.org/web/20030812184751/http://www.gallup-international.com/survey15.htm] showed that only about one sixth of Europeans attend regular religious services, less than half gave God "high importance", and only about 40% believe in a "personal God". Nevertheless, the large majority considered that they "belong" to a religious denomination.
