Thanks for a more in depth look at this phenomena.
I wonder if this "speaking of tongues" introduced into the church eminates from such beliefs as "witchcraft".
If one stands back and looks at this, to me, it mirrors such.I came across this article recently and wondered if it were a possibility .....
"In Africa one of the most prominent issues- spiritually speaking- is witchcraft. In my experience here in Tanzania I have witnessed the effects of the Africans' involvement in witchcraft. My first encounter was a few weeks ago when we were doing door to door evangelism. Pastor took us to the home of a woman who is a member of our church. The woman called Pastor to cast out a demon that she thought was in her daughter. The daughter, "Grace", came into the room with a deep sadness in her eyes. Her grandmother played a significant role in teaching Grace to rely on witch doctors and to send demons to other people. We spent three days talking to Grace, speaking truth into her life, getting to know her story, and showing her love. Grace had a painful problem in her stomach which felt like something was moving up and down her insides. On the third day Grace returned with trinkets that she wanted us to destroy. She had been given the trinkets by the witch doctor to use for witchcraft activities. Grace accepted the Lord and the next thing I know Grace is writhing on the floor and Pastor is casting out a demon from her. Her body lost complete control, even to the point that she urinated on the floor. It took two of us to hold her legs down. A few moments later, Grace stands up, set free from the demon that influenced her. She smiled, gave us huge hugs, and returned home with her mother after offering us enthusiastic gratitude. After she left, Pastor looked at me, "Amanda, you have many questions, yes?" "Pastor, you have no idea."
