This commentary by Friedrich Spitta is well known for its examination of the authenticity and date of authorship of 1 and 2 Peter and Jude. Combining exegetical with intertextual analysis, Spitta argues for the priority of 1 Peter, and for the authenticity of 2 Peter. The book discusses other issues drawn out by exegetical analysis, all leveraged to serve Spitta’s theses about authenticity and authorship. This commentary is written in German.
