/*
Oce nas,
koji si na nebesima,
da se sveti ime Tvoje,
da dodje carstvo Tvoje,
da bude volja Tvoja,
i na zemlji, kao i na nebu.
Hleb nas nasusni daj nam danas,
i oprosti nam dugove nase,
kao sto i mi oprastamo duznicima svojim,
i ne uvedi nas u iskusenje,
no izbavi nas od zloga.
Jer je Tvoje Carstvo,
i sila, i slava,
u vekove vekova.
Amin.
