The theme of this paper is to show whether religiosity has a particular role in preventing corruption. Corruption is a complex social phenomenon that has far-reaching negative consequences for society. Within sociology, one subset of sociological definitions by corruption considers processes that neglect responsibility for the public order, while the other subset considers that a certain process can be characterized as corruption when it is in accordance with public opinion. Corruption destroys many values and therefore if one does not attempt to suppress such behavior, it begins to affect almost all parts of society. It also destroys human dignity and from the religious perspective it is destroying human within its reach. Religion has always offered answers to questions related to morality and it clearly indicated which behaviors are moral and which are not. Religiosity affects decisions that human brings in his daily life. The moral principles that are rooted in human helps him to make the right decisions related to his actions. Therefore, religiosity can be an important component in the fight against corruption. This struggle can take place on three levels: individual, public, and ecclesiastical. Corruption is a characteristic phenomenon for countries in transition, as well as for Croatia. The transition brings a number of changes and new values that are trying to be implemented in a new political and economic system. The transition process in Croatia was covered by two specifics, the parallel conduct of the Homeland War for Independence and the process of conversion and privatization. These two specifics have facilitated the emergence of corruption in Croatia, that is, they have become fertile ground for corruption.
