Looking up these scriptures you have just cited. and there not even quoteing the scripture right. one of the reasons that it's wrong is because Joseph wasn't his blood father? He was born of a virgin and Joseph was his father not blood father.

The blood line was pointing where he would come from, He could not be born of any normal conception because he was to be born of a virgin. So the blood line just pointed to what family. These are just people takeing it out of contex and distorting it.
