Well...I have a newsflash for you: ALL my translations (which number about 12 or so) say otherwise. I'm supposed to believe that all those various teams of language scholars got it wrong over all these years?
To whom did Paul address his Roman's epistle: To everyone in the world or to the saints?
They wrote into what they wanted. This is a close literal translation:
For I say by the grace being given to me, to every one being among you, to not be high-minded above what you must think; but to think to be of a sound mind; to each as God apportioned a measure of faith. Romans 12:3
