“They aren’t worshipping at all; they perform.”
Had an interesting experience on this at a church attended by my husband’s aunt. Our church uses only organ and piano and the occasional violin or flute special number. This church had a band. At any rate, the sermon featured a few “Let us pray” interludes and once, while praying, I felt the floor of the building shake a bit (this being California earthquake and volcano territory, I was slightly concerned). I opened my eyes to see the band hustling up the side aisle to be in place to strike up the notes as the prayer was ending.
My friend plays drums in a band at a cowboy church in Tx and he is kind of a heathen ;)
