Theoretically placeable within the framework of the secularization versus post-secularism debate, this research employs an aggregated religiosity index as an instrument to compare Western and former Communist Eastern Europe during the globalization era in terms of area trends in religiosity. Structured in eighteen differently weighted components corresponding to three core dimensions of religiosity, i.e. beliefs, practice, and affiliation, the index confirms that over the past decade, while in the West (and Central Europe as well) secularization trends have continued, albeit at (...) different rates and content variations, globalization seems to have finally “stepped in” in the East, where the spectacular religious revival of the 1990s has been considerably slowed down, apparently entering a plateau phase, although the remarkable both denominational and religiosity diversity in the area urges to caution in any generalizing statements.
