I have a degree in Religious Studies and the convoluted hoops to jump through to get to that rationale are still beyond me! The theology just doesn’t make sense!

I choose to find the Deep philosophical meaning in Star Trek.

like when Spock said to t'pring having is not SO pleasing a THING as wanting.

Intelligent people don't accept it. You bring a good point though. The whole religion machine revolves around early indoctrination towards submission using guilt, so people won't question those things or eternal punishment. It has work wonders for years when people was isolated. Internet is the new sheriff, people keeps awaking and free the shackles of psychological oppression. Day in day out the process will continue towards complete freedom

The internal logic is that Adam, as the father of mankind, became a flawed person and that flaw was passed down by inheritance. Jesus was to be the father of a people freed from that flaw through grace. The Catholic Church, for one, seems to be content to see the Genesis story as an allegory, ignoring the problem of believing a real person died to save the world from the sin of an allegorical man.

Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned - Romans 5:12.
For if, by the trespass of the one man, death reigned through that one man, how much more will those who receive God’s abundant provision of grace and of the gift of righteousness reign in life through the one man, Jesus Christ! - Romans 5:17.
Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins. - 1 John 4:10.
