Many academics estimate that Mark’s Gospel in its “authentic” form (however they define that slippery word) ends at the eighth verse of the sixteenth chapter. Three women enter Jesus’ tomb, find a living young man there instead of Jesus’ corpse, and promptly exhibit symptoms of clinical shock.
Well they might. They had watched the Romans spend the day-before-last torturing Jesus to death. Since then the women had been counting on performing the funeral rites of their faith. Now suddenly, they learn that that is impossible. The narrator states with emphasis that the frightened women didn’t talk about their experience in the tomb to anyone. The end.
Actually, not the end, not since the Second Century at the latest. The “earliest and best” surviving manuscripts (mainly two from the Fourth Century, link and link, whose testimony about Mark‘s ending may be mutually dependent) do end at 16:8. However, comments from early authors support awareness of additional verses after 16:8 having been part of Mark, including pieces from 16:9-20. The “third oldest” surviving high-quality manuscript includes 16:9-20, and a bit more besides, see below. Even so, two generations separate Mark‘s estimated composition date from the earliest surviving mention of what may have been composed.
This post is the first of three considering whether 16:14 is an admissible estimate for an “authentic” ending of Mark. The finding of this first post is narrow. Verses 16:9 through 16:14 differ enough from verses 16:15 through 16:20 to suggest separate authorship. Whether or not verses 16:9-14 may actually be “authentic” is left for later posts.
