As acknowledged by you, Mary and Joseph’s wedding had not yet been consummated, and that while more than an engagement, in Jewish culture, the marriage had not been finalized. If you study scripture, you also know that Joseph considered divorcing Mary because of her pregnancy. It seems you wish to play a game of biblical “gotchya” Certainly not an example of loving one’s neighbor from someone who wishes to spend eternity with Christ.
Besides, my post wasn't addressed to you.
