The message of the Baptist is a message that time is out of joint, that the present is presence in which the past and future merge: "A man who comes after me has surpassed me because he was before me" [John 1:30, NIV]. That man, Jesus, the word become flesh, will later say, "before Abraham was I am" [8:58]. The logic of 4G is the logic of a late mediaeval painting depicting 'before' and 'after' events, such as Adam and Eve at once basking in the Garden of Eden and being cast out.
This tincture of time, or better, atemporal time, even the causality-defying atemporal sequencing of events, sets up the wonderful Wedding at Cana [John 2]:
On the third day a wedding took place at Cana in Galilee. Jesus' mother was there,
The historical kernel of the pericope is forever lost in the evangelist's sense of time and timing. Whether the Johannine community is privvy to an authentic tradition of a wedding in or near Galilee during the ministry of Jesus shall remain an open question open to conjecture. Still, 4G is after after something bigger than history; it want to locate the truth, the way and the life (not necessarily in that order). While the wedding at Cana might be simulacra to us today, it is Jesus' first foray into semiosis, or at least the Johannine Jesus' first foray.
The wedding at Cana depicts a Christ already in the midst of things, already upon the scene, shaping and being shaped by the discourse in which he moves. His own time moves the narrative of 4G while the narrative moves Jesus to move his own time. His hour remains in the future until the wine situation dictates otherwise. The brimming ablution jars take on water on one side of the event and spills out wine on the other. This sign is a semiotically reduced saturated phenomenon. Only Jesus, his mother and disciples know the legend by which the action must be read: they have the hermeneutic that allows the event to be released in the icon. For the master of the banquet, the bridegroom has merely held the best for last. At best, they are merely perplexed, and perhaps somewhat grateful (what Jean-Luc Marion might call 'bedazzlement'). For those who are open to the event, what issues from the jars is new time, a time of 'faith' and 'glory.' The messianic wine heralds the beginning of wine-tinctured time, even as it announces the second half of the celebration, lubricated with the best wine, a libation bereft of even an ounce of hangover. A new time within time.
At Cana, events release other events. The Messiah appears in the outflowing of wine, which iconically redirects the intuition of the disciples to the person centering the Christ-event, the logos dwelling with us. The wine lets their gaze pass into miracle, and into the divine within and through the icon. It is a saturated phenomenon that breeds another saturated phenomenon: the event. It is true, that the master of the banquet shares in a saturated phenomenon as well---that of the idol---the very excess of the best wine. But in this moment, his gaze is overwhelmed with only the idolic excess. It remains to be seen if that idol of excess will yield to the icon for him and those of his moment.
