I like your perspective and wish Christianity aligned more with your post than whatever it’s doing now.
I’m not Christian, but I have observed that the worship of the cross and Christ's death is directly tied to the theological idea of salvation, especially with evangelicals. If his death is the single most important part of your faith, then the cross becomes a symbol and reminder that you’re saved and not going to hell. It was primed to become a symbol and eventually an idol.
I also think historically the cross as a symbol for Christianity comes from the Greek letter chi (x) in the spelling of Christ. “X-tians” was a shorthand form way before the “taking Christ out of Christmas” nonsense.
But to the original point of the Klan burning the cross: I’ve read that they argue that cross burning is a medieval European affirmation of faith, something that is doing double duty of arguing that it’s an expression of their faith and connecting them to their “racial” roots.
Depends on how fixated a faith is on the “sacrifice of the Lamb.” There’s one interpretation that Jesus’ suffering and death is what appeased God and fulfilled the prophecy and ended the law of Moses. If you’re the kind of person that buys into God being the sort of deity that wants to kill himself in order to satisfy his own bloodlust, then yeah, I could see Christ’s death being the more important part.
Surely the resurrection should be emphasized as the result, but the death is what God demanded to atone for the sins of the world. The resurrection was just proof that he held up his end of the bargain.
I think that the Christ story suffers from the audience knowing details about the story that the characters don’t to the point that the big miracle at the end falls flat. Everyone just ends up focusing on the mechanics of Christs death rather than its purpose.
