Well, Paul, I didn’t recognize you! But no, the Apostle Paul saw the need for “groups,” etc.
The "group" to which I refer is the demand for centralized organization, authority of Rome. That does not exist in the Scriptures. There were hundreds of separate, independent gatherings, congregations, assemblies meeting all over the world by the end of the first century. Paul saw no one group as superior or controlling the believers. He had little regard for reputations and apparently neither did God Himself (Gal. 2:6).
So, gathering together with other believers and attending to the teaching of the apostles, fellowship, breaking of bread, and prayer is not the same thing as needing a "group" (Acts 2:42).
