The idea was that what was considered to be divine blood had the power of redemption, but we are still talking blood sacrifice here, no matter which way you cut it. But again, Jesus was a Nazarene, whose teachings did NOT include those of blood sacrifice. These doctrines came from the pagan religions. Jesus was crucified for sedition on the one hand, and blasphemy on the other. The notion of sin redemption was added later.
One might say that no sacrificial host, whether grain or animal, had been sufficient enough in the eyes of God. The only acceptable host was God himself in the flesh, and that person was Jesus.
