SODOM & GOMORRAH: There is much undue controversy regarding Jesus’ bloodline.
Fictional works such as The Da Vinci Code make the claim that Jesus and Mary Magdalene married and had children, thus perpetuating Jesus’ bloodline to present times. Atheistic criticisms also argue that there is a discrepancy between the two lists of Jesus’ ancestors, which means that the Biblical account is contradictory and likely false.
As to the first, it is hardly worth dignifying the claim with a response. All that is appropriate to point out is that Jesus Christ was the supernatural incarnation of God on earth and God had already taken the nation of Israel as His bride. To marry and procreate with another would call into question the arguments that the Lord makes against Israel, saying that they were and will be impatient and not wait for their true husband (thus leading to the great falling away).
The second argument is worth more attention since it addresses Jesus’ bloodline as it is actually mentioned in the Bible. In Luke and Matthew there are two different genealogies listed.
In Matthew, Jesus descends from Adam and from Adam’s descendant David, through his son Nathan. This is the natural and legal bloodline of Jesus Christ through birth.
In Luke 3:23, the verse reads “And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli,” and it follows with Jesus’ bloodline all the way back to Adam through David’s son Solomon. This phrase “as was supposed” is key to understanding this genealogy In Greek it translates to “according to Law”. Since Joseph married Mary, Jesus was legally Joseph’s son but not actually (as Mary had a virgin birth).
Jesus is legally recognized as being the rightful inheritor of the royal line through Solomon as well as physically being of the line of the priesthood through Nathan. Jesus Christ is simultaneously the High Priest and the King, as the two are united in one person.
