Then, emboldened by the observation of Peter, with a courage reviving from his awe-struck stupefaction, entered in, therefore, the other disciple also, he who came first to the sepulcher. Surely the charge that this writer, under the teaching of second-century tendencies, was systematically endeavoring to lower the common estimate of Peter in favor of John, breaks to pieces on the self-condemnation, which is here recorded.
The writer, whoever he was, emphasizes his own smaller courage, his tardy recognition of the fact; but he adds, And he saw, and believed. According to Augustine, Erasmus, and Luther, he believed what Mary had said.
He saw now that the tomb was empty, and believed her report, whether it went on to describe the first angelic message or not; but Lucke, Lange, Meyer, and Moulton, following Chrysostom, etc., rightly interpret "he believed" that Jesus had not been taken by others from the grave.
He saw there were no signs of haste or confusion, or of a rifled tomb. He believed that he had risen, that this death of his had been done away, that he was living, as he said. This is one of the most vivid indications that the writer assumes acquaintance with the most inward experience of that disciple whom Jesus loved.
Luke says that "Peter wondered in himself at that which had happened." John tells us that, from that moment, the whole thing flashed upon himself. There was something for him to see which shed a burning light upon Holy Scripture, upon the promises and acts of Jesus; and he "believed" in the triumph which had been achieved.
Godet thinks more—he believed in the Messiah-ship and Sonship in a sense which had not dawned upon him before. The apostle seems to link himself with those who had the smaller and less perfect benediction subsequently pronounced upon Thomas.
