A Pentecostal Church for the Deaf

Last night I ate an evening dessert with Valeriy Gaidachuck and his wife Maria. "Valera" was recently elected to become the next overseer of our church movement in the St. Petersberg region. During our conversation, he mentioned that one of our churches is for the deaf and dumb -- or more precisely stated for the hearing impaired.

On one hand, I find it great that there is a church dedicated to reaching this segment of society. But I couldn't help but to ask how they hold their services. Belonging to a Pentecostal tradition that holds that tongues speech (as described in Acts 2) is the initial evidence of spirit baptism, I couldn't help but wonder how these folks "experience Pentecost."

• Do they speak in unknown tongues? If so, how would they know it?
• What would a good old-fashioned pentecostal prayer sound, uh, look like?
  
• How do they worship corporately?
  
• What role does music play?
  

To make a long story short, the members there are able to use the voices, although it may be quite awkward to our ears. And they depend on an inner confirmation when they have had an encounter with the Holy Spirit. Well... come to think of it....
