In the Croatian Constitution, Article 40. guarantees the freedom of conscience and religion and the free public manifestation of religion or belief. Likewise, Article 41. states that all religious communities are equal before the law and separated from the state and that religious communities are free to perform, in accordance with the law, public service of religious ceremonies, establish schools, institutions, other institutes, social and charitable institutions and manage them, and enjoy the protection and assistance of the state in their activities.
