The Church and politics are faced with the same problems of the outflow of membership and believers. Politics approached this problem by branding and using trends in political communication such as personalization, celebritization and authenticity. Through the use of these forms, some of the most popular names in politics arose, which intrigued the general public for political issues. At the same time, in the Catholic Church grew a trend of the popularization of YouTube preachers, political and sports celebrity Catholics, which arouses interest in religion and the Church by using the same trends. This paper shows that the same trends are present in political communication and in religion, more specifically in the Catholic Church. The paper researches the presence of political communication trends on the example of Catholic celebrity Marin Miletić and leaves room for further research into communication trends among popular Catholics who gather hundreds of thousands of followers, become informal authorities and the biggest influencers for the brand of the Catholic Church in Croatia. It remains an open question whether the hierarchical Church in Croatia will begin to think about language and style and what message are the believers sending by clinging to YouTube Catholic stars, whether it will finally begin to communicate strategically and include them in the strategy as influencers for the brand.
