People charge that what Pentecostals and Charismatics are doing in their churches today is not the same as what the early Christians were doing. How would anyone know? None of us were there. When you read critic's exegesis of First Corinthians 14 for example, you soon see that everyone is having to read between the lines and then wing it. In a babel of tongues, they talk about tongues.
However, without any confusion or doubt, we can categorically assert that what people call church today in the mainline churches (non-Pentecostal) could NOT possibly be what was going on in the Corinthian church. Whatever they were doing sounded pretty worked up and resulted in Paul asking them to tone it down as it was off-putting to nonbelievers. The only actions that might be off-putting to the nonbeliever in most churches today would be the sounds of loud snores.
