Abstract
The three monotheistic religions, as opposed to “non-revealed” religions, are closely related: affirming their monotheism, they also accommodate supernatural beings other than God. While a certain rationalization is evident in other aspects of their organization and their beliefs, their attitudes are different in their relations with society, Islam and Judaism having more similarities with each other than with Christianity. In its early stages, Christianity drew away from the theocratic route, subsequently returning to it, before drawing away once more. The rupture with Judaism is a real one. Christianity also moved more rapidly towards laicism and, in its modern form, is evolving towards a religion without dogma. Paradoxically, the Catholic Church, the most centralized, has had to adapt to the new emancipating conception of reason, probably because it has never proposed the establishment of the kingdom of God on earth. Today, modern thinkers are bourgeois or socialist first, before being Christian or Jewish. The author expects the same development to occur in Islam.
