Rabbi Dov Lior: Gentile sperm leads to barbaric offspring
Sefer HaChinuch (a book of Jewish law) states that the character traits of the father pass on to the son. If the father is not Jewish, what character traits could he have? Traits of cruelty, of barbarism! These are not traits that characterize the people of Israel. A person born to Jewish parents, even if they weren’t raised on the Torah – there are things that are passed on (to him) in the blood, it’s genetic. If the father is a gentile, then the child is deprived of these things. I even read in books that sometimes the crime, the difficult traits, the bitterness – a child that comes from these traits? It’s no surprise that he won’t have the qualities that characterize the people of Israel.
