Law and religion do not mix. This is one of the fallacious maxims of recent years and that unfortunately brings several misunderstandings when it comes to the relationship between the state and the religious phenomena. It is not hard to see that countless perceptions on the subject, when presented in the media, academic, social and legal fields, do not take into account the constitutional foundations, the cultural values and, especially, the spiritual character of the human being as the structuring of human life. Nowadays, Brazil has been facing political and legal problems in view of the lack of understanding of the principle of Secularity applied in the Brazilian context. By electing an openly religious President, defender of the customs and practices of his religious belief, the comprehension of the subject is necessary to set aside misconceptions, in order to address the issue with the seriousness and scientificity that it deserves. In this sense, the purpose of this article is to clarify what it means to be a secular Brazilian State, aiming to demonstrate, as a result, that the secular model adopted in Brazil does not mean the absence of religiousness in the public sphere, but the guarantee and protection of all its expressions.
