Chris and Casey discuss the nature, practices, and organization of the Christians during the time of the apostles (the 1st century AD). They note the spiritual, familial, and progressive characteristics of these believers, as mainly described in the New Testament. Also, they explain how the final common practices and structure of these assemblies (aka churches) are not merely historical facts, but ideal examples for most Christians today. Some key topics discussed are Christian leadership, mutual service of believers, the Lord's Supper, and the discipline of sinning brethren.
