The aim of this paper is to analyse the ways of communication of the Catholic Church in Croatia on the topic of abortion on their portals. Although the Republic of Croatia is constitutionally secular, over 90% of the population declare themselves to be Catholics. Therefore, the activity of the Church has a great influence on politics and society. Since these principles are of a conservative and traditional nature, there is a conflict with a liberal and progressive way of life. The rights of women in Croatia are regulated by law, which enables them to have the right to a legal and safe abortion in hospitals. This goes against Catholi principles, which is why the Catholic Church seeks to ban abortion entirely. On their portals they publish their views on that topic, which are analysed to identify how they send messages to the believers. Both sides, for and against abortion, are argued in this paper. The history of propaganda, manipulation techniques and religious propaganda are defined and ethical and medical views on abortion, communication of the Catholic Church through the above- mentioned portals, women's rights and laws in Croatia are analysed, as well as the case of Mirela Čavajda and the media coverage of the debate between the conflicting parties.
