Christian church life in America is encountering unprecedented change. The older traditional mainline churches are in steep decline. World-wide, Christianity is growing at the fastest rate ever, and most of that is in Pentecostal expressions. Why aren’t traditional churches growing? What can these older churches do in response? These are fundamental questions I am trying to address, drawing on tools from psychology and sociology that are basic to my discipline of Organizational Behavior. I bring a passion for classical theology as applied in my 30 years of pastoral ministry.
