AT:  I don't claim to be an expert "on everything."  I do find topics interesting and seek to know more about them....thank goodness for Google...otherwise I'd have to live in a library. 
You have your own very narrow definition of Christian and Christian Church.  You also exclude thousands of Christian Churches and millions of Christians as not being "true" Christians.  I simply provide you with the widespread definitions of the terms.  You choose to reject those definitions and condemn those millions of Christians to hell.   I looked up "Ecclesiology" (In Christian theology, Ecclesiology is the study of the Christian Church, the origins of Christianity, its relationship to Jesus, its role in salvation, its polity, its discipline, its destiny, and its leadership)  Obviously, you have studied authors and scholars who represent your view. That's not unusual to adopt the views of those you study.  But, it important to remember there are other views..held by billions of Christians. GCrum
