J. A. Headington and Joseph Franklin. A Book of Gems, or Choice Selections from the Writings of Benjamin Franklin. St. Louis: John Burns, 1879, p. 230:
We find some brethren call a few members of the church who sit together and lead the singing a choir. This is no choir in the popular sense, nor is it at all objectionable, specially if the singing is so conducted that the members generally sing. But this is not the meaning of choir. The choir in a church is composed of artistic performers, who sing for the church; sing difficult pieces that the masses can not sing, for music and musical display, to attract, entertain and gratify the people–to charm them with music. These are professional singers, chosen without any regard to their piety, and frequently without any regard to their moral character. They sing to show how they can sing, amuse and entertain.
