This article introduces some discussion on the limitations of the distinction between laicidad and secularization in Latin America (and to a lesser extent, the notion of religious freedom), mainly highlighting the problem of the colonial origin of these conceptions and their relationship with the liberal hegemonic political framework of the field. The paper’s thesis is that the boundaries for achieving a secular context in the region are not only connected to the lack of secular policies but to the application of limited concepts on the separation between church and state, and the impact of this emphasis on a reductionist vision of the religious diversity phenomenon and its link with the socio-political processes of the region. Our propose, finally, is to review these ideas in the light of the concept of radical democracy, and the contribution of this category in the broadening of the processes of institutionalization of religious identity configurations. We will take as an example of application the debates raised by the Pavez vs. Chile case in the Inter-American Court, resolved in the year 2021.
