In this paper we analyse the religion like a cultural expression which determine the social
action. Specifically, we asked which are the general characteristics who define this social practice, how it expression influences to collective and individual identity and how the religion can exacerbate the beliefs with base in the negation of the others creeds. Also, we study some questions of religious thought as: where emerge the idea of religion? How they are building and about which concepts gyrate this? All those are the questions that emerge when study the religions like a social phenomenon, and they are orienting the present article, which pretend to be a modest art state about the forms that the study of the religions and the culture had been generally analyzed like human expressions.
