Teaching and researching the Gospel of John for thirty years has led author Mary L. Coloe to an awareness of the importance of the wisdom literature to make sense of Johannine theology, language, and symbolism: in the prologue, with Nicodemus, in the Bread of Life discourse, with Mary and Lazarus, and in the culminating "Hour." She also shows how the late Second Temple theology expressed in the books of Sirach and Wisdom, considered deuterocanonical and omitted from some Bible editions, are essential intertexts. Only the book of Wisdom speaks of "the reign of God" (Wis 10:10), "eternity life" (Wis 5:15), and the ambrosia maintaining angelic life (Wis 19:21)-all concepts found in John's Gospel.

While the Gospel explicitly states the Logos was enfleshed in Jesus, this is also true of Sophia. Coloe makes the case that Jesus's words and deeds embody Sophia throughout the narrative. At the beginning of each chapter Coloe provides text from the later wisdom books that resonate with the Gospel passage, drawing Sophia out of the shadows.
