Bishop Spong indicated that we Christians should not perceive God as a God who demands barbaric acts like human sacrifice to appease his sense of justice. He uses the term child abuse and I just call it more of what it would be if the myth was real; murder.
I say needlessly because God has no needs. He only has wants and no decent God would want to needlessly sacrifice his son.
If a Sacrifice were required, God would not send a boy to do a manís job and he would be man enough to step up himself.
If you were to dare judge this issue or scenario of God, --- knowing that he planned to have Jesus sacrificed even before creating the potential for sin, would you find God criminally liable for child abuse and murder?
