Ain’t it da trut’! I was raised in the CoG back in the '50s and '60s, when it was a holiness denomination: no movies, no smoking/drinking, no divorce, uncut hair on women–the list went on and on. Everything that was “of the world” was taboo. Now the ladies in our Catholic parish have more of a “holiness” look than the women at the CoG where I sometimes have to make an appearance for a family funeral.
With regard to the “pandemonium,” I can remember some camp meetings that were rather “pandemonious,” to the point where trying to carry on a conversation was pointless.
However, the local congregations that I attended up to the point where I left the denomination (1996) were rather sedate. However, I went to a service at an independent charismatic church (accompanying a family member that I was visiting), started by a graduate of the CoG’s Lee University, and the sound level there was so high that it was painful. If it had been a factory, OSHA would have required everyone in the building to wear hearing protection. It was a moderate-size room with a low ceiling; there was no reason for the level of amplification that they were using. There apparently is still a mind-set that volume = anointing. Makes it kinda hard to hear the “still small voice.”
