Those who claim Christ as Savior express a wide set of opinions on a varied set of topics. I became acutely aware of this after I left organized religion. I fully believed at one time the true Christian looked, spoke and believed similarly to me, regardless of his or her particular stream. The "true" Christian was "sold out to Jesus", full of the Holy Spirit, someone dedicated to all things Christian and exhibited strong character as a result.
Once I had left the organized church, I told myself I wanted to think again. I had allowed myself to think only what I had been told was safe to think for too long. Eighteen years to be exact, twelve of these as an elder. (This is not intended to suggest that organized religion does this routinely. It is simply what I experienced.) I began to read and often from what before had been labeled by my teachers and spiritual leaders as inappropriate theology. Since I no longer recognized their authority over what and what not to read, I read widely, literally across a breadth of Christian exposition.
I discovered the parameters of a significant diversity of "Christian" opinion were much larger than I had supposed. I simply wanted to know, "What is right belief?"
It actually came together for me in a secular, graduate sociology course. Much of current Christian theology seems intended to make the world a better place.
Beginning in the middle:
Sociology is a modern, established scientific discipline in disarray. Some would even say that it is not even truly a science, though a degree in sociology is a bachelor's degree in science. Many colleges have even begun to dismantle their sociology departments. As reported to me then in 2002, the problem is that sociologists cannot agree on a unifying sociological theory for why society functions as it does. I think I know why; and the answer explains, in part, the great diversity of Christian opinion about what Christianity should be.
