“The Commission also noted that there are no obstacles to accepting a name in a sacrament of baptism in a different national sound (for example: John - John; John - Zhanna),” the website of the Russian Orthodox Church (ROC) specified.
Also, the Russian Orthodox Church allowed to baptize children under the names of saints of other Orthodox churches, and adults who were baptized, if their name was not available in the months of the local Orthodox churches, choose other baptismal names from the month, preferably in tune with the civil ones.
Earlier, Patriarch of Moscow and All Russia Kirill allowed the possibility of partial worship in modern Russian, and not just in Church Slavonic.
