Over, under, and through John’s story of Jesus are unforgettable ideas and concepts, profoundly simple and simply profound, for the author’s own audience and beyond. These ideas did not originate in a vacuum. They have recurred and been repeated before and after the writing of the Fourth Gospel. For this reason we will examine the meaning of its words and themes in the context of its Jewish-Greco-Roman milieu. Much of our intertextual understanding will be derived from alleged parallels that involve comparisons of similar vocabulary and phrases, as well as parallel concepts and images from the Old Testament, the Dead Sea Scrolls, Philo, and other relevant writings. Such parallels will help to determine the meaning of a word or expression, the translation of a particular language, determining any direct influences upon the Fourth Gospel, parallel traditions, or the influence of its ideas, as a creative and inspiring work of later antiquity.
