We come now to the origin of the "choirs." As Zinzendorf studied the Gospel story, he came to the conclusion that in the life of Jesus Christ there was something specially suitable to each estate in life. For the married people there was Christ, the Bridegroom of His Bride, the Church; for the single Brethren, the "man about thirty years of age"; for the single Sisters, the Virgin Mary; for the children, the boy in the temple asking questions. The idea took root. The more rapidly the settlement grew, the more need there was for division and organization. For each class the Master had a special message, and, therefore, each class must have its special meetings and study its special duties. For this purpose a band of single men--led by the ascetic Martin Linner, who slept on bare boards--agreed to live in one house, spent the evenings in united study, and thus laid the basis of the Single Brethren's Choir {Aug. 29th, 1728.}. For the same purpose the single young women, led by Anna Nitschmann, agreed to live in a "Single Sisters' House," and made a covenant with one another that henceforward they would not make matrimony the highest aim in life, but would rather, like Mary of Bethany, sit at the feet of Christ and learn of Him {May 4th, 1730.}. For the same purpose the married people met at a love-feast, formed the "married choir," and promised to lead a pure and holy life {Sept. 7th, 1733.}, "so that their children might be plants of righteousness." For the same purpose the children, in due time, were formed into a "children's choir." The whole aim was efficiency and order. At first the unions were voluntary; in time they became official. As the years rolled on the whole congregation was systematically divided into ten "choirs," as follows:--The married choir, the widowers, the widows, the Single Brethren, the Single Sisters, the youths, the great girls, the little boys, the little girls, the infants in arms. Each choir had its own president, its own special services, its own festival day, its own love-feasts. Of these choirs the most important were those of the Single Brethren and Single Sisters. As the Brethren at Herrnhut were soon to be busy in evangelistic labours, they found it convenient to have in their ranks a number of men and women who were not bound down by family ties; and though the young people took no celibate vows, they often kept single through life for the sake of the growing cause.
