The religion of sacrifice was never constructive. It was created by the demons to control humans through intimidation. Yet Paul resurrected it as the supposed purpose of Christianity.

The purpose of sacrifice in religion is to destroy something of value to show that the controllers are the highest value. In remote areas, people had to kill their children on an altar as a test of allegiance to the demons. In more developed areas, substitutes were allowed, such as sacrificing animals or incense.

The religion of sacrifice was supposed to have been abandoned in God's religion. For Paul to reinstitute it in Christianity was a total perversion. Paul was a liar and a fraud. The fakes who promote Paul's version of religion are liars and corrupters of Christianity.

Christ taught people to evaluate evidence and think for themselves (Mat 7:8, 13:16, 15:10)(Mark 4:13, 8:18)(Luke 8:18, 10:23,24 12:54-57, 24:45)(John 7:24, 8:43). There is no other protection from liars and fakes in religion.

The early part of God's religion had the purpose of teaching what is wrong with sacrifice, not promoting it. The prophets said sacrifice is not what God wants (Isaiah 1:11-20)(Jer 7:22)(Hosea 6:6)(Psalms 40:7, 50:8-15)(Mat 9:13, 12:7)(Mark 12:33). But it could not be accomplished all at once. So people were first taught to redesign sacrifice to have it represent repentance instead of allegiance to the demons. After people learned what morality is, they were supposed to have totally abandoned sacrifice in religion.

This purpose is extremely obvious in the way the book of Genesis was written. Genesis was written as a string of allegories made up by prophets, with traces of history, for the purpose of teaching what morality is and why it matters. The Abraham story had the purpose of showing that the existing religious assumption was that God would want Abraham to sacrifice his child as a test of allegiance to God. After showing that such a stupid assumption existed, God then intervened for the purpose of creating a different religion, where sacrifice was a murderous fraud which needs to be replaced by morality based upon sustaining life rather than destroying life.

The rest of Genesis showed that people had no moral bearings at that time, because the religion of the demons was creating their problems rather than solving them. To fix that problem, the first thing that would be needed was ten simple rules summarizing morality. Ten rules could never be enough. People would need to understand morality, and teaching it was Christ's purpose.
