I also attended my daughter's church which was Pentecostal. There the congregation engaged in tongues and running. At some moment one or two people would take off running around the church. This was a little scary, but I was a pre VII Catholic, so any expressions of faith or love were deemed out of bounds. But the tongues were still respectfully sung/spoken there.
I have seen some of the laughing and 'slaying in the spirit' on the religious TV programs and have come to the conclusion that to those who are not just faking it, all of these activities are an emotional response to an overwhelming stimulus. Is it contact with the Holy Spirit that is the overwhelming stimulus? I believe that it is occasionally. Just as some may express joy or love with tears or jumping up and down, I believe some of these people are so overwhelmed by the touch of the Holy Spirit that they respond in a way that many of us may believe to be strange. But I think the Father accepts any form of worship and praise that is offered to Him by His children.
