I do not like praise teams. I do not think they are scriptural.My response was as follows:
I totally understand you not liking praise teams; I don't much care for them either, but for practical reasons, such as their volume overpowering the congregational singing. It's also just plain uncomfortable to see a group leading singing if you've never been exposed to it, especially if that group contains women, and you're strongly convinced they shouldn't be "leading" in a mixed assembly.
Totally understandable why someone wouldn't like them.
But as to being unscriptural? If you were a first century christian, and suddenly heard a 21st century church singing four-part harmony instead of the traditional "scriptural" chanting with which you grew up, you'd probably think that was unscriptural.
You might even think that having a song-leader standing before the congregation, waving his arms to the beat, was unscriptural.
Sometimes what we deem as "unscriptural" is really nothing more than "unfamiliar". Not always; but sometimes.
Just something to consider.
