How many of the songs we use "lack the Biblical teaching stressed in Paul's words" versus songs that represent "the teaching office of the church?" (GPTG, 97)

As regards Burroughs' second case of conscience, I believe there is at least one occasion when one must refrain from a "holy duty" if he is not prepared. This is when receiving communion, as Paul specifically instructs in 1 Corinthians 11: "Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty concerning the body and blood of the Lord" etc.. I can think of specific times when I've had to refrain from partaking in the Lord's Table, usually while I'm still on the platform providing music.

For all other occasions, however, I do think he makes a good point for making sure that you aren't leaving off a duty for the wrong reason. He warns, "consider that this is but a temptation" (71), and encourages with the words "though you cannot find your heart prepared as you desire, the very falling upon it will fit you for it" (74).
