Fictitious Worship

“Those who set up a fictitious worship, merely worship and adore their own delirious fancies; indeed, they would never dare so to trifle with God, had they not previously fashioned him after their own childish conceits.” ~ Institutes of the Christian Religion

Musical Instruments in the Worship of God

“Musical instruments in celebrating the praises of God would be no more suitable than the burning of incense, the lighting of lamps, and the restoration of the other shadows of the law. The Papists therefore, have foolishly borrowed, this, as well as many other things, from the Jews. Men who are fond of outward pomp may delight in that noise; but the simplicity which God recommends to us by the apostles is far more pleasing to him. Paul allows us to bless God in the public assembly of the saints, only in a known tongue (1 Corinthians 14:16) What shall we then say of chanting, which fills the ears with nothing but an empty sound?”
