This dissertation seeks to understand how racism in its religious bias is capable of producing and reproducing objectively and subjectively violence, as well as how much this issue crosses and/or is crossed by the Law. Thus, African-based religions are the ones that suffer most from such racialized issues, since they derive from the African diasporic process, from the 15th century, fruit of slavery. The present research starts from a theoretical and critical analysis, questioning and revisiting some concepts dear to the State and the law, such as (religious) freedom, secularism and democracy, together with a critical study about whiteness. Content analysis is used as an investigation technique (Bardin, 1977), as well as those of speech and document analysis to explore three important nationally published reports on religious intolerance. Finally, the law is criticized, especially constitutional law. Finally, the Law is strained from its own instruments, when making a critical analysis of Extraordinary Appel 494.601 and its context, which deals with the constitutionality of animal sacrifices in rituals of African-based religions. In this way, it is possible to see how Law - in its languages and institutions - does not account for the plurality that exists in Afro-religious practices, nor is it able, due to institutional and structural racism in Brazil, to fully contemplate the demands of theses religious groups.
