Starting with the revitalization of religion that has been taking place since the 1970s, this paper opposes two different points of view on secularization. Firstly, there are proponents of the thesis that say secularization has been indisputably at work since the modern era until today, while on the other hand there are proponents who claim that secularization is actually a myth, and that religion is still alive as it once was. Among them there are American sociologists who represent the so-called a new paradigm or a religious market theory. In this paper, the assumptions of this paradigm is critically questioned both in the theoretical sense and in the examples of different countries of Western and post-communist Europe, where it is shown that this paradigm is not universally applicable. In conclusion, the paper establishes that secularization is certainly an indisputable fact, however it is not universally and deterministically applicable, but should be studied respecting the socio-economic and traditional context of each particular country.
