to a virgin pledged to be married to a man whose name was Joseph, of the house of David. The virgin's name was Mary.
All four of the Gospel writers evidence their belief that Christ was born of a virgin.  Matthew spelled it out categorically, presenting it from the viewpoint of Joseph.  Mark did not mention it, but in his report of the gossip at Nazareth selected the words "Is not this the carpenter?" rather than the other form of it, "Is not this the carpenter's son?" as it is in Matthew (Mark 6:3;  Matthew 13:55).  Of course, the gossip existed in both forms; but Matthew, who had recorded the virgin birth, selected one form of it; and Mark, who had not recorded the virgin birth, was careful to choose the other form in order to avoid any implication against the virgin birth. From this we are certain that Mark knew of the doctrine and that he believed it.  Extensive New Testament reference to Jesus as "Son of God" cannot be understood otherwise than in the sense of the unique sonship of Jesus Christ, every such reference being equivalent to denial that Jesus was begotten by any mortal father.  Therefore, the fact of the virgin birth is affirmed in every reference.  "Only begotten," as used by John (John 1:18; 3:18), carries the same message of confirmation from the Gospel of John.
