Mormons already knew the Da Vinci Code
I discover that some of the Eastern papers represent me as a great blasphemer, because I said, in my lecture on Marriage, at our last Conference, that Jesus Christ was married at Cana of Galilee, that Mary, Martha, and others were his wives, and that he begat children.
All that I have to say in reply to that charge is this—they worship a Savior that is too pure and holy to fulfil the commands of his Father. I worship one that is just pure and holy enough "to fulfil all righteousness;" not only the righteous law of baptism, but the still more righteous and important law "to multiply and replenish the earth." Startle not at this! for even the Father himself honored that law by coming down to Mary, without a natural body, and begetting a son; and if Jesus begat children, he only "did that which he had seen his Father do."

The Da Vinci code raises some big questions for the Christian world, but we have had these thoughts floating around Mormonism for 150 years. They pose no threat to any true Latter-day Saint who understands that it is necessary to be wed and have offspring in order to attain Exaltation, and that we are following in the Savior's footsteps.
It will be borne in mind that once on a time, there was a marriage in Cana of Galilee; and on a careful reading of that transaction, it will be discovered that no less a person than Jesus Christ was married on that occasion. If he was never married, his intimacy with Mary and Martha, and the other Mary also whom Jesus loved, must have been highly unbecoming and improper to say the best of it.
I will venture to say that if Jesus Christ were now to pass through the most pious countries in Christendom with a train of women,. such as used to follow him, fondling about him, combing his hair, anointing him with precious ointment, washing his feet with tears, and wiping them with the hair of their heads and unmarried, or even married, he would be mobbed, tarred, and feathered, and rode, not on an ass, but on a rail. What did the old Prophet mean when he said (speaking of Christ), "He shall see his seed, prolong his days, &c." Did Jesus consider it necessary to fulfil every righteous command or requirement of his Father? He most certainly did. This he witnessed by submitting to baptism under the hands of John. "Thus it becometh us to fulfil all righteousness," said he. Was it God's commandment to man, in the beginning, to multiply and replenish the earth? None can deny this, neither that it was a righteous command; for upon an obedience to this, depended the perpetuity of our race. Did Christ come to destroy the law or the Prophets, or to fulfil them? He came to fulfil. Did he multiply, and did he see his seed? Did he honour his Father's law by complying with it, or did he not? Others may do as they like, but I will not charge our Saviour with neglect or transgression in this or any other duty.
At this doctrine the long-faced hypocrite and the sanctimonious bigot will probably cry, blasphemy! Horrid perversion of God's word! Wicked wretch! He is not fit to live! &c., &c. But the wise and reflecting will consider, read, and pray. If God be not our Father, grandfather, or great grandfather, or some kind of a father in reality, in deed and in truth, why are we taught to say, "Our Father who art in heaven?" How much soever of holy horror of this doctrine may excite in persons not impregnated with the blood of Christ, and whose minds are consequently dark and benighted, it may excite still more when they are told that if none of the natural blood of Christ flows in their veins, they are not the chosen or elect of God. Object not, therefore, too strongly against the marriage of Christ, but remember that in the last days, secret and hidden things must come to light, and that your life also (which is the blood) is hid with Christ in God.

Not only do we assert that Jesus Christ was married, but that he was a polygamist. Just wait until it falls upon the Christian world to digest that piece of information.
