"Knowing that his time was short (2 Peter 1:13-15) and these churches faced immediate danger (2 Peter 2:1-3), Peter called upon the readers to refresh their memories (2 Peter 1:13) and stimulate their thinking (2 Peter 3:1-2) so that they would remember his teaching (2 Peter 1:15). He challenged the believers to become more mature in their faith by adding to it specific Christians virtues, thereby becoming effective and productive in their knowledge of Jesus Christ (2 Peter 1:5-9). The Old and New Testament writers were set forth as their authority for their faith (2 Peter 1:12-21, 3:2, 3:15-16). Peter desired they become strong in their faith to withstand the false teachers that had crept in and adversely affected the churches. In his denunciation of them, he described their conduct, their condemnation, and their characteristics (2 Peter chapter 2), and also that they ridiculed the Lord’s Second Coming (2 Peter 3:3-7). For the Christians, Peter taught that the Second Coming is the incentive for holy living (2 Peter 3:14). After a final warning, Peter again encouraged them to grow in the grace and knowledge of their Lord and Savior Jesus Christ. He concluded with a word of praise to his Lord and Savior (2 Peter 3:18)."
"We have now passed over all the canonical writings of Peter that are extant; and it is worthy of remark that, in no place of the two epistles already examined, nor in any of this apostle's sayings in any other parts of the sacred writings, do we find any of the peculiar tenets of the Romish Church: not one word of his or the pope's supremacy; not one word of those of affect to be his successors; nothing of the infallibility claimed by those pretended successors; nothing of purgatory, penances, pilgrimages, auricular confession, power of the keys, indulgences, extreme unction, masses, and prayers for the dead; and not one word on the most essential doctrine of the Romish Church, transubstantiation."
