After this he went down to Capernaum with his mother and brothers and his disciples. There they stayed for a few days.
This linking verse is an important one. Does it complete the water into wine passage of does it introduce the cleansing of the Temple passage. If the latter then you have to postulate two Temple cleansings; one at the beginning of his ministry and one (as recounted in the Synoptics) at the end. If you take the former view then you must accept that John's gospel is not chronologically, but thematically organized.
I tend to take the former view. No gospel records two cleansings and there seems to be no difference in the message behind the two stories. So, as with the previous story, the theme is paramount; the message is the same: the old has gone; the new has come.
