Urban von Wahlde's radically new, three-volume commentary on the Gospel and Letters of John is the most detailed study of the composition of the Johannine literature ever put forth by an American scholar. Nearly all of the problems confronted by those who study John have to do with the literary strata of the Gospel of John and their relation to the composition of the Letters of John. With an archaeologist's precision, and engaging a whole range of scholarly contributions in this area, von Wahlde digs down to the foundations and exposes three distinct literary strata in the development of the Johannine tradition. Volume 1 gives detailed evidence identifying and listing the criteria for each stratum. Volumes 2 and 3 apply those criteria to the Gospel and Letters of John respectively.
