Matthew Levering, in his Jesus and the Demise of Death, writes:

Wright considers that the metaphor of sleep describes the death of the body, “while the real person—however we want to describe him or her—continues.” In this regard, Wright’s position is the largely same as that of John Calvin, who disagreed with Martin Luther’s view that those who die in Christ are “asleep” until the day of resurrection. For Calvin, “the souls of the righteous, after their warfare is ended, obtain blessed rest where in joy they wait for the fruition of promised glory.”

There’s no footnote or other reference regarding this view that Luther allegedly held. I’m no Luther scholar. Anybody know what Levering might be talking about here? It seems foreign to the Lutheran theology I’ve learned.
