The goal of promoting the Croatian language in the religious service was initially brought and introduced by the 10th century bishop Gregory of Nin, which resulted in a conflict with the Pope, later to be put down by him.
Eesmärgi edendada slaavi keelt jumalateenistusel võttis esmakordselt kasutusele 10. sajandi piiskop Grgur Ninski, mis andis tulemuseks konflikti paavstiga, kes hiljem tema poolt kukutati.
