I haven't read the Divinci Code but as far as I know, it is a bad knock-off of earlier pseudo-historical accounts such as "Holy Blood, Holy Grail", etc. However, the idea that Jesus and Mary Magdalene had a special relationship is quite old; the idea is probably largely motivated by the quote below from the Gospel of Philip (a part of the Nag Hammadi library discovered in 1945) which was apparently written around 150-250 AD:

And the companion of the [...] Mary Magdalene. [...] loved her more than all the disciples, and used to kiss her often on her mouth. The rest of the disciples [...]. They said to him "Why do you love her more than all of us?" The Savior answered and said to them,"Why do I not love you like her? When a blind man and one who sees are both together in darkness, they are no different from one another. When the light comes, then he who sees will see the light, and he who is blind will remain in darkness."

Here's another passage from the Gospel of Philip that likely inspired the idea that Jesus and Mary Magdalene were married:

"There were three who always walked with the Lord: Mary, his mother, and her sister, and Magdalene, the one who was called his companion. His sister and his mother and his companion were each a Mary."

What if it were true? Would it really matter?
