Well, it looks like the Apostle Paul has some opinions on church services. In 1 Corinthians 14, he argues that speaking in tongues is all well and good, but it's not really useful if there's no one there to interpret it. Because, you know, it's a bit hard to get the message across when no one knows what you're saying. He also says that when it comes to worship, order is important and that prophecy is better than speaking in tongues. So, in short, Paul's advice is, if you're gonna do something, do it right!
