The early church met in homes. They met simply. They met cheaply. They met for edification.
Does today's church have to meet in homes? I don't think so. However, God has given us in scripture a model for gathering simply as his body for the purpose of edification. This can likely occur just as easily in a coffee shop, park, or store front as it does in a home.
What we do not see in the bible is churches coming together in large groups on Sundays for the purpose of worship in large, expensive buildings. What happens today is foreign to scripture.
When we think about the family of God, we must ask ourselves whether or not we have any sort of road map to follow. Has God provided us with any sort of directions, or have we been left to simply figure things out on our own? While we are to follow the leading of the Holy Spirit, it seems as if today more and more Christians are blaming increasingly odd, bizarre, and just plain stupid behavior on the Spirit. What, therefore, are we to do?
We look in the bible. We see a model of church life. We follow the principles we see. It's that simple.
It is unavoidable that the early believers met simply. When they gathered, it was a family meeting. It was usually in homes. It was unstructured. It was for edification.
Home get-togethers is what we read about. The question is, "Will we follow the principle we see in scripture?"
