Heidegger's Bible Handbook: 2 Peter: Authorship
1. The Author of the Epistle is Saint Peter. The error of Erasmus and Grotius concerning this noted.
That this Epistle was also written by the same Author as above, namely, Saint Peter, the Apostle of Christ, is abundantly proven out of 2 Peter 1:1, 2, 16-18; 3:1, 2, 15. And under the name of Peter it was reckoned in the Canon already of old by the Council of Laodicea in canon 59, Athanasius in his Synopsi, Jerome in his Epistle to Paulinus, Augustine, and other ancients. In vain does Erasmus disagree, alleging diversity of style. He ought to have ascribed that, such as it is, to a diversity of material and argument, not of author. Grotius also, insisting that this Epistle was published, not by the Apostle Peter, but by Simon, successor of James in the Episcopate of Jerusalem, is refuted openly by Hammond and others.
