"The music should be well-ordered and clear, so that the congregation can understand it."

"The music of the spheres is the music of God."

"I find that I must work harder than anyone else, and then it is still not enough."

"The aim and final end of all music should be none other than the glory of God and the refreshment of the soul."

"All music should have no other end and aim than the glory of God and the soul's refreshment; where this is not observed, there will be no true music but only devilish hubbub and discord."
