The scope of work is to discuss the extent of the right to religious freedom in Brazil, focusing on the use of religious symbols in public space. The Constitution of the Republic 1988 brings in its text, as a fundamental right, the prerogatives of belief and worship. Assuming that such freedom is external, that there is a right to express a belief or non- belief, the study will address the religious conduct in public space as a requirement of self-affirmation and recognition of the religious citizen through the public exercise of its beliefs. In order to contribute to the analysis of brazilian reality about the proposed theme, precedents of the United States of America, Germany and France will be adressed. Finally, the study will include an analysis of Brazilian reality from its legislation and constitutional doctrine as well as through analysis of conflicting cases wich happened in the society and which were motivated by the exercise of religious beliefs, and will also examine whether a public official can use symbols referring to its religious beliefs while working without thereby to violate the brazilian constitution.
