AUG. Now we must consider how the Lord appeared after the resurrection. For Mark says, Now when Jesus was risen early the first day of the week, he appeared first to Mary Magdalene, out of whom he had cast seven devils.[...]
AUG. But how was this done the last time? The last occasion on which the Apostles saw the Lord upon earth happened forty days after the resurrection; but would He then have upbraided them for not believing those who had seen Him risen, when they themselves had so often seen Him after His resurrection? It remains therefore that we should understand that Mark wished to say it in few words, and said for the last time, because it was the last time that He showed Himself that day, as night was coming on, when the disciples returned from the country into Jerusalem, and found, as Luke says, the eleven and those who were with them, speaking together concerning the resurrection of our Lord.
But there were some there who did not believe; when these then were sitting at meat, (as Mark says,) and were still speaking, (as Luke relates,) The Lord stood in the midst of them, and said to them, Peace be to you; as Luke and John say. The rebuke therefore which Mark here mentions, must have been amongst those words, which Luke and John say, that the Lord at that time spoke to the disciples. But another question is raised, how Mark says that He appeared when the eleven sat at meat, if the time was the first part of the night on the Lord's day, when John plainly says that Thomas was not with them, who, we believe, had gone out, before the Lord came in to them, after those two had returned from the village, and spoken with the eleven, as we find in Luke's Gospel.
But Luke in his relation leaves room for supposing that Thomas went out first, while they spoke these things, and that the Lord entered afterwards; Mark however from his saying, for the last time he appeared to the eleven as they sat at meat, forces us to believe that he was there, unless indeed, though one of them was absent he chose to call them the eleven, because the company of the Apostles was then called by this number, before Matthias was chosen into the place of Judas. Or if this be a harsh way of understanding it, let us understand that it means that after many appearances, He showed Himself for the last time, that is, on the fortieth clay, to the Apostles, as they sat at meat, and that since He was about to ascend from them, He rather wished on that day to reprove them for not having believed those who had seen Him risen before seeing Him themselves, because after His ascension even the Gentiles on their preaching were to believe a Gospel, which they had not seen.
And so the same Mark immediately after that rebuke says, And he said to them, Go you into all the world, and preach the Gospel to every creature. And lower down, He that believes not shall be condemned. Since then they were to preach this, were not they themselves to be first rebuked, because before they saw the Lord they had not believed those to who He had first appeared?
Interesting comparison. I especially like the mention of not havig choosen Matthias in there. Another time marker.
