Glad to see that Peter Leithart is reading through Markus Barth’s excellent book Acquittal by Resurrection. More people should read Markus Barth. Wipf & Stock do some really good imprints of his shorter volumes.
Barth does a great job of showing that Jesus’ death AND resurrection is what constitutes the basis of justification … not just Jesus’ death.
Don’t believe me, read Romans 4:25!
Barth is exactly right to emphasize that the resurrection has to be integral to justification. Without it, we won’t be able to demonstrate the justice of justification in a universally comprehensible way.
