The biggest hole I see is the notion that blood has to be poured out in order to satisfy god in the first place. Why does a benevolent god require a bloody death of another human in order to be satisfied?
If god set the divine rules in the first place, he just as easily could have said that "I need 3 Hail Mary's and 2 Our Father's in order to be satisfied". OK, your the boss so whatever you say, that's the LAW. The notion that millions of gallons of blood needed to be poured out in both human and animal sacrifices in order to please god is "ungodlike".
just saying!
