Abstract
In Western Europe more and more sociologists of religion are talking about religious individualization instead of secularization to describe the religious change in modern societies. Institutional forms of religion, especially traditional Christian Churches, are increasingly losing their social significance; new forms of religion, which are not so highly institutionalized and more syncretistic, are, however, emerging. The author raises the question whether this theoretical model conceptualized for Western Europe can be applied to the analysis of religious developments in Eastern Europe. The result of the analysis carried out on the basis of a representative survey in 11 Eastern and Central European countries is that new forms of religiousness outside the Church are emerging in Eastern and Central Europe. In predominantly Catholic countries, these forms stand in contrast to the traditional forms of religion, in more secularized countries, they are not an alternative to institutionalized forms of religion.
