This article presents two proposals : first, it suggests that the ecumenical project of a common corporate organization be extended to a project spurred by all the world religions in view of a just global order , peaceful and with more solidarity;  secondly, it suggests that this project is no longer justified by the search for identity and religious-cultural homogenization currently impossible before the already established multiculturalism, but rather from the assertion of irreducibility of the other as the motto for an approximation between the different religious and cultural conceptions in every nation and globally. The importance of having as a starting point the irreducibility of the other becomes practicable, first, by doing justice to violations against every religious-cultural identity in particular and, secondly, by realizing that because it is impossible a kind of strict standardization from a specific religious and cultural belief, only peace and reciprocity, streamlined through all religions, could solve the currently existing conflicts, many of them characterized by religious and cultural violence against difference.
