Wes,

I have read and appreciate the regulatory principle concerning non-biblical singing which many Reformed congregations seem to have abandoned. I would very much like to visit a church that holds to that teaching but there are none in the area.

But, to me, if a pastor can preach a sermon that is not verbatim from the bible, he can also select hymns that he or others have written that are not in the bible. The key is "Do the sermon and hymns hold fast the faithful word?" I believe singing is always teaching and an exercise of authority: "he may be able, by sound doctrine, both to exhort and convince the gainsayers."
