LOL. might want to try a somewhat smaller brush. I've attended a Pentecostal church & no such thing took place on any given Sunday. "Usual" or otherwise. They're not all the same. Actually the most out of order behavior I ever saw was at a Vineyard church.
Well, then, you've attended a very LOW key Pentecostal church. All the ones in my area are full scale wailing, speaking in tongues and being "slain in the spirit".
Your church sounds pretty boring for a Pentecostal one.
LOL!
