The book of Jude shares striking similarities with 2 Peter, particularly in its warnings against false teachers. Considering that Jude identifies himself as 'a brother of James' (Jude 1:1), and given James's emphasis on practical obedience and good works, how might Jude's letter function as a complement to James's, particularly in addressing the problem of antinomianism (the belief that grace frees Christians from moral law)?
