So you agree that the local "rabble" were right, and that Christ is the son of Joseph -- and not the Son of God? OK . . .
Would you include Mary amongst the "rabble"? Did she not call Joseph the "father" of Jesus?
Luke 2:
[48] And when they saw him they were astonished; and his mother said to him, "Son, why have you treated us so? Behold, your father and I have been looking for you anxiously."
[49] And he said to them, "How is it that you sought me? Did you not know that I must be in my Father's house?"
[50] And they did not understand the saying which he spoke to them.
[51] And he went down with them and came to Nazareth, and was obedient to them; and his mother kept all these things in her heart.
[52] And Jesus increased in wisdom and in stature, and in favor with God and man.
