Genesis 3:20
And Adam called his wife's name Eve; because she was the mother of all living.
Jesus is unique in that He is the "seed of the Woman" as prophesied in Genesis 3:15. But of course He had no human father: His Father was God. His mother, Mary, was a human being, descendant of Adam and Eve. Thus via His mother's side of the family, Jesus too is in the same family, the human race.
This is the significance of the genealogies If this were not true, the proper response to the genealogies--- and a good chunk of the OT --- would be "who cares?" They would be irrelevant.
And you have told us earlier that you are certain GOD used an ovum from Mary to form the body of JESUS. Which we have shown to you makes GOD a defrauder of Joseph since the incarnation of Jesus in Mary’s womb occurred AFTER Mary was already espoused to Joseph thus all her reproductive genetic future was espoused to Joseph, from which you claim GOD took an ovum for His making of Jesus. But of course you also impugn GOD as not being capable of making Jesus without using a Mary ovum yet you agree Adam is of the human family. Typical catholic mumbo jumbo duplicity.
