"We are witnesses to these things," said Peter. Yet as the gospel for the second Sunday of Easter opens, "these things" do not include Jesus' resurrection. That morning Peter had seen an empty tomb with some scattered linens. He had witnessed absence, not resurrection. At that point, he had not even witnessed Jesus' death—he had missed his chance. Yet soon Peter becomes one of the boldest and most powerful of witnesses to Jesus' message, death and resurrection. Clearly something happened.
