In 2 Peter 3:15–17, Peter warns his readers against those who twist Paul’s letters, and he associates their misinterpretations with “the error of lawless people.” In this article, I examine both the immediate and broader context of this passage as well as the specific language Peter uses to characterize those who twist Paul’s letters. I argue that 2 Peter 3:15–17 constitutes a warning against antinomians who misinterpret Paul’s letters to justify and encourage transgression of the Law of Moses.
