I think it is very important indeed that where Paul says if anyone preach a gospel other than that which we preached you put "contrary to Scripture". And you put the whole thing in quotes as though that was what was in the original text instead of a paraphrase. The way it is written, the test is at least consistent with the idea of a tradition passed on by word of mouth. The way you changed it from what is actually in the Bible while putting it in quotes as though it were in the Bible instead of something originating with you (or with the version you were quoting) it is more a quote in favor of the Old Testament.
I cannot say how important to the entire nature of the discussion here it is to find out how exactly it happened that something was presented as a quote from Scripture when in fact it was changed to support one side in an argument. Without such an accounting I will have to check everything you present as a quote - and that would be a nuisance.
