Rumors are more destructive than any facts.
We choose to use a mix of acapella and instrumental music for the reason of the Great Commission. No outsider was going to understand the issue of acapella and instrumental, and our mission was to be fishers of men, not preserve the aquarium. We took it on ourselves to make and mature disciples. So, appauld your leaders if their motivation is to make more disciples or something else laudable. I had heard rumors that our leadership was going to introduce instrumental music in the assembly.
