First we must take heed that in music be not put the whole sum and effect of godliness and of the worshipping of God, which among the papists they do almost everywhere think, that they have fully worshipped God when they have long and much sung and piped.
Further, we must take heed that in it be not put merit or remission of sins.
Thirdly, that singing be not so much used and occupied in the church that there be no time, in a manner, left to preach the Word of God and holy doctrine; whereby it cometh to pass that the people depart out of the church full of music and harmony, but yet hunger-baned and fasting as touching heavenly food on doctrine.
Fourthly, that rich and large stipends be not so appointed for musicians that either very little or, in a manner, nothing is provided for the ministers which labor in the word of God.
Fifthly, neither may that broken and quavering music be used wherewith the standers-by are so letted that they cannot understand the words, not though they would never so fain.
Lastly, we must take heed that in the church nothing be sung without choice, but only those things which are contained in the holy scriptures, or which are by just reason gathered out of them, and do exactly agree with the word of God.
