Regarding 2 Tim. 3:16, "all scripture is inspired by God".....since the only scripture at the time this was written was the Old Testament (Hebrew scriptures, if you prefer), would it make sense to reason that this scripture cannot be used by itself to support New Testament writings?....that the scriptures referred to in this verse were the Old Testament?
As an apostle Paul had authority, but to me it seems that some of the things Paul wrote were related as "commands" to the congregations, whereas other things were only his suggestions or his perspective and that it was up to the individuals to decide for themselves.
Your thoughts on this?
