In an interview for Nova revija in 1926 he stated that "clericalism means abuse of the most sacred feelings of religion in order to destroy the family, to demolish people in order to gain political power."[18] He would often repeat the slogan: Believe in God, but not in the priest. He supported the establishment of the Indigenous Croatian Catholic Church, and its separation from the Vatican. The secularist association "Voice of Reason - The Movement for a Secular Croatia" uses his portrait as its logo.
