ABSTRACT
This chapter deals with the problem of the relationship existing between the system's constitution and construction process and its genesis. The personality of the founder of a religion is described as being mobile, meaning that they are capable of going beyond the symbolic boundaries of a consolidated, existing belief system and of charting new boundaries. The chapter explains syncretism through expansion in opposition to a syncretism through cancellation or crushing. Shamanism is a belief system that puts in order a world populated by spirits, appointing someone to mediate with this world. In prophetic religions, because the power of communication is initially pure word, it is subsequently the object of a systematic work of interpretation. The match played in the Christian religious socio-linguistic field revolved around the issue of how to delineate the symbolic boundaries that had to establish once and for all which words could be used to express in what all believers had to believe.
