Liturgical Guidelines in Sunday Worship
The main conclusion is as follows: The biblical texts themselves do not provide explicit instructions or recommendations regarding a specific number of hymns in Sunday services. Instead, it is the liturgical regulations and traditional church guidelines that dictate the order and number of hymns during the service.For example, one source notes that on Sunday “the Regulations prescribe singing 10 hymn verses – which is very many, it can be said, the maximum normative variant for the number of ‘Gospodi, vozvah’ hymn verses” (source: link txt). This normative arrangement is part of the church regulations, rather than a direct command from the Bible.Furthermore, another document records that “the canon of the Sunday service consists of nine songs” (source: link txt). It is also noted that “every Sunday service includes the mandatory singing of hymn verses during the praise section, which, in turn, comprises between 4 and 8 hymn verses” – and again, this is a rule of the liturgical structure, not a reference to a specific biblical decree (source: link txt).Thus, although the service tradition is based on biblical motifs and psalms, the specific numerical regulations (such as 10 hymn verses or 9 songs in the canon) are the result of established church practices and regulations, not directives explicitly recorded in the sacred texts.Supporting citation(s):"Gospodi, vozvah – these are the common psalms from the Hours. They should all be sung at every service, including on Sunday. Thereafter, hymn verses on 'Gospodi, vozvah' follow. On Sunday, the Regulations prescribe singing 10 hymn verses – which is very many, it can be said, the maximum normative variant for the number of 'Gospodi, vozvah' hymn verses, with more than this number occurring only in exceptional cases; only twice a year do they exceed 10. This further attests to the importance of Sunday." (source: link txt)"The canon of the Sunday service consists of nine songs." (source: link txt)
