2 Peter 3:16
He writes the same way in all his letters, speaking in them of these matters. His letters contain some things that are hard to understand, which ignorant and unstable people distort, as they do the other Scriptures, to their own destruction.
I mean, when Peter said "his letters" ---> Did Peter mean [his Scriptures] ?
As I'm from a non-English speaking country, this is quite confusing for me. Because in our language words, a Scripture is a Bible - while a letter is not a Bible. And of course, in this modern time - no one will say "I'm writing a Bible" :).
Suppose Peter is writing for his fellow Christians.
Someone phone him "Hi Peter, what are you doing ?".
Peter answer "I'm writing a scripture".
What will be in the caller's mind ?
A. Peter is writing a Bible
B. Peter is writing a letter (not a Bible)
