Some things shouldn't be ignored

There is a wide ranging discussion spread over a couple of blogs that boils down to one's view of "regulated worship" and "Christian Liberty".   While both constructs seem to have significant basis in scripture, they are still an attempt to corral a bunch of widely separated scriptures and to give those scriptures a label to express a scriptural concept in a sort of shorthand.

At one of the blog I posited that this whole discussion really boiled down to how one answers a few questions, and listed the questions.   Since they were ignored over there, and since some folks who might not comment there might comment here, I'm going to list them here.

1. Are there any limits on what is appropriate in corporate worship at all?
2. If a book contains any rules does that automatically classify it as a "rule book"?
3. If a book, or compilation of books contain a number of different genres of literature, dose that fact automatically invalidate one of the genres?
4. Does the human construct of "Christian Liberty" automatically trump the human construct of "Regulated Worship", even though both have scriptural support? If so, why?
5. Does the construct of "Christian Liberty" have any limits at all?

I honestly think that #1 and #5 are the most significant, but that's just me.
