The relationship between religion and political parties depends on the legitimating capital that both parties bring into interaction with each other. Consequently, the religionization of politics as a process of introducing religiously guided themes into political structures and the politicization of religion, the process of using political power and domination by the Catholic Church to achieve its own goals, are two significant trends that capture the attention of contemporary sociology of religion. Both processes influence political decisions and consequently social structures shaped by a mixture of religious and profane opinions. In this paper, the emphasis is placed on concretizing both processes through current issues of abortion, same-sex marriage and religious education in schools in Croatian society. An insight is set into the statutes of Croatian political parties, which form their positions on the basis of their connection with the Church, while recognizing the contradictions between left-wing and right-wing parties on the political spectrum. The analysis of religious and political questions raises the question of how much influence the Church actually has on the adoption of legal provisions in Croatia, and is our society, when it comes to moral questions, subordinated exclusively to the traditional values?
