Was the Gospel of John written in critical response to the Gospel of Thomas, an early collection of Jesus's sayings? Or was it directed to the Christians among whom Thomas originated? Ismo Dunderberg challenges these views, arguing that the two gospels were written at about the same time but without knowledge of each other. He also offers a thorough discussion of the identity and functions of the enigmatic Beloved Disciple in the Gospel of John, throwing new light on this figure by comparing it to other beloved' disciples of Jesus in early Christian literature.
