For here is recognition that the absence of mutual, undistorted, unpolluted relating, which leads ultimately to death, is anathema within Jesus' ontology—so much so that death has no hold on him. The resurrection is not an addendum or a postscript. What is true of Jesus and his atoning work up to and including his final moments on the cross is also true, indeed more so, once the tomb is empty.Atonement for a "Sinless" Society, p. 185
I especially like the line "The resurrection is not an addendum or a postscript." So true! The resurrection is the heart and soul of Christianity. Without it, we are still dead in our sins, as Paul says in I Corinthians 15.
