Nowhere in the Bible does Jesus claim to be born of a virgin. Just like nowhere in the Bible does Jesus claim to be God.
Jesus picked his 12 disciples when he started his ministry at the age of 30. They were total strangers and knew nothing about Jesus or his early childhood. His ministry lasted only 3 years before he was crucified. Which is why we have conflicting reports from the four gospel writers.
Luke names Joseph son of Heli as Jesus’s father.
Luke 3:23 Now Jesus himself was about thirty years old when he began his ministry. He was the son, so it was thought, of Joseph,
the son of Heli, 24 the son of Matthat,
Matthew names Joseph son of Jacob as Jesus father.
Matthew 1:15 Matthan the father of Jacob,
16 and Jacob the father of Joseph, the husband of Mary, and Mary was the mother of Jesus who is called the Messiah.
Mark does not mention anything about Jesus’s virgin birth. Neither does John.
We also learn Mary had other children. In Mark 6:3 Isn’t this the carpenter? Isn’t this Mary’s son and the brother of James, Joseph,[a] Judas and Simon? Aren’t his sisters here with us?” And they took offense at him.
We even know what his family thought of Jesus’s virgin birth.
Mark 3:21 When his family heard about this, they went to take charge of him, for they said, “He is out of his mind.”
