Well every church should have a Pastor (overseer leader). I ave never been to a house church but what would be the difference in being in a small congregation. I have however found that many people don't like the mega church as well as the other way around. However it does not matter as long as the bible is being taught.
I'm a shut-in unable to get to church, much of my time is spent in His word. I'm excited about the home church idea. As I study I am pulled more and more from the tradition and man organization of our big churches.
