Two genealogical records purporting to give the lineage of Jesus are found in the New Testament, one in the first chapter of Matthew, the other in the third chapter of Luke.
These records present several apparent discrepancies, but such have been satisfactorily reconciled by the research of specialists in Jewish genealogy. No detailed analysis of the matter will be attempted here; but it should be borne in mind that the consensus of judgment on the part of investigators is that Matthew’s account is that of the royal lineage, establishing the order of sequence among the legal successors to the throne of David, while the account given by Luke is a personal pedigree, demonstrating descent from David without adherence to the line of legal succession to the throne through primogeniture or nearness of kin. Luke’s record is regarded by many, however, as the pedigree of Mary, while Matthew’s is accepted as that of Joseph. The all important fact to be remembered is that the Child promised by Gabriel to Mary, the virginal bride of Joseph, would be born in the royal line.
A personal genealogy of Joseph was essentially that of Mary also, for they were cousins. Joseph is named as son of Jacob by Matthew, and as son of Heli by Luke; but Jacob and Heli were brothers, and it appears that one of the two was the father of Joseph and the other the father of Mary and therefore father-in-law to Joseph. That Mary was of Davidic descent is plainly set forth in many scriptures; for since Jesus was to be born of Mary, yet was not begotten by Joseph, who was the reputed, and, according to the law of the Jews, the legal, father, the blood of David’s posterity was given to the body of Jesus through Mary alone. Our Lord, though repeatedly addressed as Son of David, never repudiated the title but accepted it as rightly applied to Himself.
Apostolic testimony stands in positive assertion of the royal heirship of Christ through earthly lineage, as witness the affirmation of Paul, the scholarly Pharisee: “Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh”; and again:
“Remember that Jesus Christ of the seed of David was raised from the dead.”
