Christianity
The body is not discarded.
Christianity does not actually teach what most people think it teaches. The idea of a disembodied soul drifting up to a cloud is closer to Greek philosophy than to the New Testament. What Christianity stakes its entire weight on is bodily resurrection — a new creation, a remade physical life. Jesus eats fish after rising. He is not a ghost. The promise is not that you will escape your body but that your body will be raised and redeemed. Death is real. Grief is real. But in this tradition, they do not have the last word.
“Death is swallowed up in victory.”
— 1 Corinthians 15:54
