Peter called Paul’s writings scripture. John was told what to write in Revelation. Add that to the consistent admonition by God (which includes Jesus) to write down what He told them just when do you think God changed His mind about writing it down?
Peter called Paul’s writings scripture.
When?
And when did Jesus say to anybody during his earthly sojourn “write this down”?
Peter called Paul's writing's..... wait for it.... writing's. That is the original meaning of the work "script" it means to write, or record.
The term scripture as something holy, came later. This is where knowledge of etymology comes in handy.
