I have been in the ministry for 36 years. As I look back over those years, one of the things that stand out is the size of the congregation seemed to reflect the confidence (or lack thereof) in the Old Testament in general and the book of Genesis in particular. The smaller the congregation the more confidence. The larger the congregation, the more skepticism. That is just my observation. But I also observe that America’s largest cities tend to be its most liberal/progressive while its smaller but vastly more numerous towns and villages tend to be its most conservative/evangelical. Maybe that’s why the early church exploded as the house church but when persecution eased and cathedrals and basilicas became prevalent the church declined.
