Celsus addresses that point as well. I was going to bring these out in order but since you mentioned it.
Quote:"Let us imagine what a Jew- let alone a philosopher- might say to Jesus: 'Is it not true, good sir, that you fabricated the story of your birth from a virgin to quiet rumourss about the true and insavoury circumstances of your origins? Is it not the case that far from being born in the royal David's city of bethlehem, you were born in a poor country town, and of a woman who earned her living by spinning? Is it not the case that when her deceit was uncovered, to wit, that she was pregnant by a roman soldier called Panthera she was driven away by her husband- the carpenter- and convicted of adultery?"
