My Catholic friend and I were talking the other night about the Virgin Mary. She doesn't even believe that she was a virgin and she doesn't believe in the immaculate conception.
If you think about it logically today, if you had a fiance that went to visit relatives for a few months and then came back pregnant and told you it was God's child, would you believe it? Would you still marry her and raise that child and believe he was the son of God?
OR - would you break off the engagement and tell her you're not gullible.
