Subiect: The history of Christian religious music is closely intertwined with the history of Church and Christian cult. The chorus is a protection of our believers and Church against malefic influences from other confessions and cults which contravenes Orthodox-Christian Religion: "There where the believers know the study of their Church, where they have learned the hymns of the Holy Liturgy, where they know how to sing wonderful hymns of Holy Parents, there, nobody of other religion cannot deceive them."
