Being on the cusp of postmodernism, I sometimes think that reading theology is hazardous to my mental health. It's come to the point that it has become very difficult to tell what is cultural and what is pure 'fact.' Sometimes I find my self asking, a la Pontius Pilate, "What IS truth?"
I hear a lot about "solo scriptura" and scriptural "inerrancy" but I have doubts that we neither mean what we say nor understand what we are saying. It is fairly certain that we really mean partial 'scriptura," picking and choosing those portions of scripture which appeal to our personal or cultural prejudices.
Take for example the current kerfluffle about sexuality. It seems to me that the NT passages we use to condemn homosexuals as 'sinners' contain other things such as greed, licentiousness, etc. which we never mention. I suspect that this interpretation is as much political as anything else.
We say that scripture is inerrant and THIS is what it means. Cultural? Political? I don't know. Myself, I believe scripture is inerrant but, and this is a great but, I just don't happen to know what scripture is being inerrant about in many cases.
So, how do I preserve my sanity? Well, how I've personally dealt with this insanity is to discard most of what I believed to be 'truth.' What have I retained? In brief, Jesus was born, He died, He was raised from the dead & He ascended into heaven, ushering in the Kingdom of God on this earth. Without these central facts, Christianity becomes nothing more than a nice worldview competing with other nice, and not so nice, worldviews. Just another philosophy of life. Just mental/philosophical masturbation. Certainly no 'truth' there..just opinion.
