The constitution guarantees freedom of religion and states that all religious communities are equal under the law. The constitution makes incitement of religious hatred illegal. Religious communities are free to publicly conduct religious services, operate schools, and operate charitable organizations.
There is no official state religion. The Catholic Church receives state financial support and other benefits established in four concordats between the government and the Holy See. These agreements allow state financing for salaries and pensions of some religious officials through government-managed pension and health funds. These agreements also stipulate state funding for religious education in public schools.
The law defines the legal position of religious communities and covers such matters as government funding and tax benefits. To obtain status as a religious community a religious group must have at least 500 members and be registered as an organization for at least five years. The state recognizes marriages conducted by registered religious communities, eliminating the need for civil registration. To be recognized legally, marriages by non-registered religious communities require civil registration. Non-registered religious communities also cannot conduct religious education in schools or access state funds in support of religious activities.
There are currently 44 registered religious communities, including Bet Israel (a Jewish group), the SOC, the Bulgarian Orthodox Church, the Christian Adventist Church, the Church of Christ, the Church of God, the Coordination of Jewish Communities in Croatia, the Croatian Old Catholic Church, the Evangelical Church, the Islamic Community of Croatia, the Macedonian Orthodox Church, the Pentecostal Church, the Reformed Christian Church, the Union of Baptist Churches, the Seventh-day Adventist Reform Movement, The Church of Jesus Christ of Latter-day Saints (Mormons), and the Union of Pentecostal Churches of Christ.
On September 12, the government signed an agreement recognizing three Protestant churches: the Church of the Full Gospel; the Word of Life Alliance of Churches, and the Protestant Reformed Christian Church.
The government requires religious education be offered in public schools, although attendance is optional. The Roman Catholic catechism is the predominant religious text used. Sixteen additional religious groups may offer religious education in schools in which there are seven or more students of a given faith. Students may opt out of religious education if they wish without providing specific grounds.
