Bultmann believed that when Paul spoke of the resurrection of the dead in 1 Corinthians 15, he inevitably wrapped the real content of what he intended to say in 'the oriental salvation myth of the Original Man.'
Thielman identifies Bultmann's demythologization program as the pivotal claim that Paul's resurrection language is mythological wrapping over an existential core, a move Käsemann radicalized into assertions of irreconcilable theological contradiction within the New Testament.
