"Where's the choir?"
In the Old Testament, one group of Levites was dedicated to the work of singing in the temple (see 1 Chron. 9:33; 25:1-8). With the coming of Jesus Christ (whose person and work were foreshadowed in the Old Testament templesee John 2:19-21), the Old Testament temple and its worship are superseded by the church as the temple of God (1 Cor. 3:16-17; 2 Cor. 6:16; Eph. 2:21). There is no indication from the pages of the New Testament or the earliest records of Christian church history that there ever was (as in the Old Testament temple) a separate choir in Christian worship.
During the Middle Ages, as worship was more and more removed from congregational participation, choirs separate from the congregation developed.
But the Protestant Reformers returned singing to the congregation, arranged for the printing of psalters and hymnals for use in the churches, and encouraged a wholehearted response of praise from the entire congregation. Indeed, congregational singing of Psalms and hymns became a hallmark of Protestant churches.
In our congregations today, we should build upon this historic Protestant emphasis. "Where's the choir?" you ask. The answer is: "It's sitting in the pews!" The entire congregation is the choir.
This has many practical implications:
