In the liturgy of St. James, the liturgy of the Jerusalem Church, a very similar share, in many instances with identical words, is assigned to the people; but a far more frequent mention is made of the choir of singers who render the Trisagion hymn, which, in St. Mark’s liturgy, is given by the people: besides the “Allelulia,” the hymn to the Virgin Mother, “O taste and see that the Lord is good,” and “The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee.” A large portion of the service, as indicated by these liturgies, was occupied by prayers, during which the people kept silence. In the matter of responses the congregation had more direct share than in the Catholic Church to-day, for now the chancel choir acts as their representatives, while the Kyrie eleison has become one of the choral portions of the Mass, and the Thrice Holy has been merged in the choral Sanctus. But in the liturgical worship, whatever may have been the case in non-liturgical observances, the share of the people was confined to these few brief ejaculations and prescribed sentences, and nothing corresponding to the congregational song of the Protestant Church can be found. Still earlier than this final issue of the ritualistic movement the singing of the people was limited to psalms and canticles, a restriction justified and perhaps occasioned by the ease with which doctrinal vagaries and mystical extravagances could be instilled into the minds of the converts by means of this very subtle and persuasive agent. The conflict of the orthodox churches with the Gnostics and Arians showed clearly the danger of unlimited license in the production and singing of hymns, for these formidable heretics drew large numbers away from the faith of the apostles by means of the choral songs which they employed everywhere for proselyting purposes. The Council of Laodicea (held between 343 and 381) decreed in its 13th Canon: “Besides the appointed singers, who mount the ambo and sing from the book, others shall not sing in the church.”[37] The exact meaning of this prohibition has not been determined, for the participation of the people in the church song did not entirely cease at this time. How generally representative this council was, or how extensive its authority, is not known; but the importance of this decree has been exaggerated by historians of music, for, at most, it serves only as a register of a fact which was an inevitable consequence of the universal hierarchical and ritualistic tendencies of the time.
