JEDNÁNÍ O DOVOLENÍ SLAVENÍ STAROSLOVANSKÉ LITURGIE PRO ČESKÉ A MORAVSKÉ DIECÉZE VE 20. LETECH 20. STOLETÍ

In response to the establishment of the Czechoslovak Church (in January 1920), which introduced using the vernacular language in the liturgy, the Czech and Moravian bishops requested permission to extend the use of the vernacular language in the liturgy and, following the Cyril and Methodius tradition, to allow the celebration of the Old Slavonic liturgy. The Holy See allowed some extension of the use of the vernacular language in the liturgy and the celebration of the Old Slavonic liturgy in selected places on selected days (approved in May 1920). This was done especially for apologetic reasons, to prevent a greater exodus of the faithful to the Czechoslovak Church. This permission was also meant to be an example of the Holy See's friendliness towards Czechoslovakia.
