Euebius of Caesarea: Long Ending of Mark Spurious

Your first question waas: How is it that the Saviour's resurrection evidently took place, in Matthew, "late on the Sabbath," but in Mark "early in the morning on the first day of the week"? The answer to this would be twofold. The actual nub of the matter is the pericope that says this. One who athetises that pericope would say that it is not found in all copies of the gospel according to Mark: accurate copies end their text of the Marcan account with the words of the young man whom the women saw, and who said to them "'Do not be afraid; it is Jesus the Nazarene that you are looking for etc. etc. ...'", after which it adds: "And when they heard this, they ran away, and said nothing to anyone, because they were frightened." That is where the text does end, in almost all copies of the gospel according to Mark. What occasionally follows in some copies, not all, would be extraneous, most particularly if it contained something contradictory to the evidence of the other evangelists.
