It bears repeating, and it is a good way to see if a person is open to reasoning even from Scripture.
Ezekiel 18.1-32 is clear that people don't inherit sin from either Adam or their parents. This false belief was once circulated around Israel in the days of Ezekiel, and the word from G-d was:
What do you mean by this proverb of yours about the land of Israel: “When parents eat unripe grapes, the children’s teeth suffer”? As surely as I live, says the Lord God, no longer will you use this proverb in Israel!...Only the one who sins will die.
People are not declared innocent by the shedding or animal or human blood. Ezekiel continues:
People are declared innocent when they act justly and responsibly.
Christians will oddly protest that this Scripture doesn't somehow apply, but G-d asks all who would oppose his thinking:
You will say, “Why doesn’t the child bear his parent’s guilt?”
G-d's answer:
If the child has acted justly and responsibly and the child kept all my regulations and observed them, then the child will surely live. Only the one who sins will die. A child won’t bear a parent’s guilt, and a parent won’t bear a child’s guilt. Those who do right will be declared innocent, and the wicked will be declared guilty.
Does a person need to have faith in blood shed on their behalf to be forgiven for some wrong? That has no effect on justice.
But if the wicked turn away from all the sins that they have committed, keep all my regulations, and act justly and responsibly, they will surely live and not die. None of the sins that they committed will be held against them, but they will live because they do the right things. Do I take pleasure in the death of the wicked? says the Lord God. Certainly not! If they change their ways, they will live.--Ezekiel 18.1-23.
At this point most Christians will quote Hebrews 9.22 which says that "there is no forgiveness without blood being shed." But these words do not come from the Hebrew Scriptures. In fact they contradict the above words of Ezekiel where G-d merely asks that "the wicked turn away from all the sins that they have committed" and "keep all my regulations, and act justly and responsibly," adding that because of doing these things "they will surely live and not die" for their sinful actions of the past. This promise is never made on the basis of requiring anyone to have faith in the shed blood of anyone or anything.
If they change their ways, they will live.
