Shared ground
These verses tie future hope (“these things” the readers are waiting for) to present moral seriousness. The writer assumes a coming evaluation and frames the present as the time to be “found” in a certain condition: peace, and a life described as “without blemish and blameless” (explicit textual claims).
The passage also treats the Lord’s apparent slowness as meaningful. The delay is not presented as failure or indifference but as “patience,” and that patience is to be “regarded as salvation” (explicit). That is, the delay is interpreted as serving a saving purpose rather than being empty time.
Finally, the writer places Paul’s letters alongside this teaching: Paul wrote “according to the wisdom given to him,” and across his letters he addresses “these things” too (explicit). The writer acknowledges that some parts of Paul are difficult, and he warns that some people distort Paul and “the other scriptures,” with ruinous results (explicit).
Where interpretation differs (only where needed)
1) “Found in peace.” Some read “peace” mainly as inner steadiness before God; others think it includes reconciled relationships in the community; many read it as both—right standing and harmony expressed in life. The phrase is broad enough to allow more than one emphasis.
2) “Without blemish and blameless.” Some take this as a call to moral perfection; others read it as directional language (a sincere, integrity-shaped life that fits the coming evaluation). The surrounding emphasis on diligence and being “found” supports the idea of a recognized, observable condition, but the text does not spell out the degree of completeness.
3) “Patience…as salvation.” Some interpret “salvation” here as an opportunity for repentance before the final day; others hear it as the Lord’s saving purpose toward his people in the delay (patient protection, not only a window of time). The text states the link (patience functions as salvation) but not the full mechanism.
4) “Other scriptures” and Paul’s status. Some conclude the writer is treating Paul’s letters as scripture in the same category as Israel’s scriptures. Others think the phrase could mean: people twist Paul and also twist the rest of scripture, without making a formal statement about Paul’s letters’ category. The wording strongly associates Paul’s writings with revered scriptural texts, but readers differ on how explicit that association is.
Why the disagreement exists
Several key phrases are compressed and somewhat open (“peace,” “salvation,” “these things,” “other scriptures”). The writer’s main point is clear—ethical seriousness, purposeful patience, and danger in distortion—but he does not define each term tightly. Also, he speaks broadly of “all” Paul’s letters without listing which ones, leaving modern readers to infer scope.
What this passage clearly contributes
It presents waiting for the Lord’s future as shaping a present moral aim: to be “found” in peace and integrity “in his sight.” It interprets the Lord’s delay as patient saving purpose rather than evidence against his promise. It also affirms continuity between this teaching and Paul’s writings, while acknowledging that some Pauline teaching is hard and can be dangerously twisted—along with “the other scriptures” (2 Peter 3:16).
