In Orthodox church, we use ancient Church-Slavonic language, not modern russian. So first time I learned the Creed, I learned it in Church-Slavonic. So it’s a bit different from modern russian translation used by the Catholic Church. For example, the word “catholic” - in Church-Slavonic, it’s translated as “sobornaya” (direct meaning of “sobor” word is council, community of faithful), and in modern russian, it’s translated as “vselenskaya” (=Universal). Other differences are not too important.
During the Mass, I follow the Creed in russian, like everyone else. In my private prayer, however, I prefer Church-Slavonic (because it’s more beautiful than russian - it’s sacred language just like Latin for any traditional catholic), but I add “and from the Son” (filioque) into it, - or, pray in latin.
I also prefer reading “Our Father” in Church-Slavonic. When I pray the Rosary, I read some “Hail Marys” in latin, some in russian and some in Church-Slavonic
Just BTW - for those who doesn’t know - there IS real Rosary in Russian Orthodox church. It’s called “God Mother’s Rule” and it was given by Our Lady to st.Seraphim of Sarov in 19th century. Like traditional catholic Rosary, it contains 150 Hail Mary’s and 15 Our Fathers, and meditations about events from Mary and Christ’s life. The “mysteries” are almost identhical to catholic ones - with only few differences. Also, the difference is in the beginning - there’s no “tail” with the crucifix; the orthodox “rule” contains 50+5 or 150+15 beads with a crucifix attached right to the circle.
