Among many (good) arguments against KJV-onlyism, I have heard the following argument:
The idea that “preservation” requires us to have 100% accurate knowledge of the original words of scripture is a standard that was not demanded by Christ or the Apostles.
To bolster this argument, it is suggested that Christ or the NT authors will occasionally base an argument on a textual variant from the OT (probably from the Septuagint) where the original reading actually says something different.
Thus, the argument goes, it is possible to acknowledge that we do not have 100% perfect accuracy in our copies while still holding to a doctrine of preservation... one defined by the belief that the message of the Bible is perfectly clear, even though some meaningful and viable textual variants exist.
I do not remember any specific passages cited where Christ or the NT authors did this sort of thing (made applications based on textual variants). Does anyone know of any?
