Jesus promised the resurrection of the body, not an afterlife as a disembodied consciousness. Despite this, the followers of Jesus have always disparaged the flesh. Their belief that humans are marked off from the rest of creation by having an immortal soul has led them to disown the fate they share with other animals. They cannot reconcile their attachment to the body with their hope of immortality. When the two come into conflict it is always the flesh that is left behind.
