In particular, it is vital to the whole thrust of John's theology that the logos becomes a human being. Sirach, somewhat loftily, could not envisage a human being ever fully fathoming Wisdom. John sees this Wisdom becoming, fully, a human being. In doing so he is still conscious of writing a new version of Genesis. The climax of the fist chapter of Genesis is the creation of the human being in the image of the creator. The climax of John's prologue is the coming to full humanness of the logos, who, in taking on so many of the characteristics of Wisdom, may be assumed also to be the divine image-bearer. When Pilate declares to the crowds, 'Here is the man,' John intends his readers to hear echoes that have been present since the very beginning. Jesus, as the logos having become flesh, is the truly human being.
