“As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.”
King James Version (KJV)
3:16 As also in all his epistles - St. Peter wrote this a little before his own and St. Paul's martyrdom. St. Paul therefore had now written all his epistles; and even from this expression we may learn that St. Peter had read them all, perhaps sent to him by St. Paul himself. Nor was he at all disgusted by what St. Paul had written concerning him in the Epistle to the Galatians. Speaking of these things - Namely, of the coming of our Lord, delayed through his longsuffering, and of the circumstances preceding and accompanying it. Which things the unlearned - They who are not taught of God. And the unstable - Wavering, double - minded, unsettled men. Wrest - As though Christ would not come. As they do also the other scriptures - Therefore St Paul's writings were now part of the scriptures. To their own destruction - But that some use the scriptures ill, is no reason why others should not use them at all.
2Pe 3:16 As also in all [his] epistles. Peter knew of many epistles, then, that Paul had written, and knew also that they contained some very profound argument, which a Jew especially found it difficult to understand (See Galatian Letter). The unlearned and unstable. The ignorant and vacillating. Wrest. Pervert and give meanings that were never meant. As [they do] also the other scriptures. The other scriptures may mean the Old Testament, or New Testament writings already written. The point to be noted is that already when Peter wrote Paul's epistles were accepted as a part of the Scriptures. Unto their own destruction. This should be a warning to all in our day who twist the Scriptures from their real meaning.
