Is there any scriptural support for the belief of convulsions/seizures being a sign of the Holy Spirit's presence? I work with a handful of Church of God members, and we frequently have friendly ecclesiastical conversations. The Church of God denomination is very prevalent in the area that I live and work. They often describe church services they have attended that involve sporadic behavior, such as spastic convulsions, falling in the floor, seizures, running around the pews and/or sanctuary, running across the top of pews, and so on.

Is there any biblical support for this kind of behavior?

My intentions are not meant to mock these services at all. Every person I know that is a member (many of whom are my very close friends) are very down to Earth, good people.

I just want to be able to bring scriptural material (if any) to our next breakfast fellowship.

NOTE: I am well aware of the argument for "speaking in tongues" being in the Bible. I am not looking for an answer concerning speaking in tongues...only physical behavior.
There is no Biblical precedent for convulsions or seizures being a sign of The Holy Spirit's presence.

Falling on the floor in a convulsion does have a Biblical precedent, but not a good one:


  When the spirit saw Jesus, it immediately threw the boy into a convulsion. He fell to the ground and rolled around, foaming at the mouth.


Mark 9:201

I'm not saying that the people you have seen are possessed. However, I do think it is wise to be very wary about this ministry. Consider carefully the fruit of the ministry - are they encouraging people to develop a relationship with Jesus or are they encouraging mere physical manifestations? If the latter, I would stay clear.

1. In verse 25 this is described as an impure spirit; Jesus says it is a deaf and mute spirit. This is also referred to as a demon.
