A cappella
Instruments have divided Christendom since their introduction into worship. They were considered a Catholic innovation, not widely practiced until the 18th century, and were opposed vigorously in worship by a number of Protestant Reformers, including Martin Luther (1483-1546), Ulrich Zwingli, John Calvin (1509-1564) and John Wesley (1703-1791). Alexander Campbell referred to the use of an instrument in worship as "a cow bell in a concert". In Sir Walter Scott's The Heart of Midlothian, the heroine, Jeanie Deans, a Scottish Presbyterian, writes to her father about the church situation she has found in England (bold added):
Why were instruments more unwelcome to Christians?
