Do you honestly believe that only a small minority of Christians in the past +/- 150 years have been interpreting scripture correctly, and that all other Christians are wrong?
Ummm. Yes, absolutely! Especially since you are greatly exaggerating your differential in amounts of persons opinions one-way or the other, AND the time-frame you are attempting to infer.
First - From Where do you draw your sources for Christian interpretation of scripture?
Second - Do you fully understand the Biblical hermeneutics, exegesis, isogesis and historical linguistics in order to make such a assertion?
Third - What is the definition of a CHRISTIAN that you are attempting to use in your assertion?
There are many more mistakes in your statement, but I would rather wait upon your answers to the above, prior to further discussion with you on the subject.
