“”All scripture is inspired by God and is useful for teaching, for refutation, for correction, and for training in righteousness, so that one who belongs to God may be competent, equipped for every good work.”

Granted, all Scripture is inspired by God.

St. Paul says Scripture is "useful" he does not say it is sufficient.

And in the context of this quote he is referring to the Old Testament not the New Testament as he tells Timothy: "because from thy infancy thou hast known the holy scriptures which can instruct thee to salvation by the faith which is in Christ Jesus." The New Testament had not yet been penned, certainly not 2 Timothy.

Further, that quote condemns the shameful Protestant attempt to truncate the Bible to accomodate their theological fantasies.

Peter affirms that Paul’s writings are themselves scripture. He says Paul’s words are twisted, that same as OTHER scripture is.

But, you miss the point.

Scripture is inspired BY GOD.

Name one other source of authority about which there is an authoritative statement that it is ITSELF “inspired BY GOD.”
