Growing up in NC I often attended revival meetings and preacher's fellowships with my Father who was a pastor. In rural independent, fundamental, Baptist churches this type of group prayer was common...even typical. Before the service, all of the men would gather in a room, one guy would be asked to lead in prayer. He would start and everyone else would, out loud, join in prayer. I'm sure the practice started in the culture some years ago and has been maintained. I have no problem with it. I have never heard anybody do such a thing in PA. People in Philly are much to quiet and reserved to pray all at one time...yeah, right!
