There is of course a retired bishop of the Episcopal church who has gone beyond a simple denial of the miracle. +John Shelby Spong went so far as to suggest that the wedding at Cana was Jesus' own.
In 2000, David H. Lane President of the Wellington Christian Apologetics Soc. wrote in "APOLOGIA" The Journal of the Wellington Christian Apologetics Society vol. 7(2/3) 2000, an excellent piece entitled "Redefining God In Man’s Image (I), A Critique of Bishop John Spong’s Revised ‘Christianity’" and described Spong's theory,
"Jesus was quite probably married, most likely to
Mary Magdalene. The account in Scripture of the
Wedding at Cana of Galilee is a record of His own
marriage as ‘proved’ by the fact that He attended
it with His mother. His case is based on the fact
that the only wedding Spong has ever attended
with his mother was his own." (p.18)
It would take a miracle to make me believe John Shelby Spong.
Incredibly, the adult Sunday School class at the Episcopal Church of Our Saviour is buying copies of Spong's latest book "Eternal Life: A New Vision: Beyond Religion, Beyond Theism, Beyond Heaven and Hell" to study this semester. (Chapter 1 is available here) I wish they all would read that entire 139 page "Apologia" vol. 7 and arm themselves with a strong defense beforehand.
