Why does Mark end at 16:8 in the earliest manuscripts?

Text and context

Mark's earliest and best manuscripts — the fourth-century codices Sinaiticus and Vaticanus, along with the earliest versional evidence — end the Gospel at 16:8: "They said nothing to anyone; for they were afraid" (Mark 16:8, WEB). The verses familiar from most English Bibles, 16:9–20 (appearances to Mary Magdalene, the road to Emmaus material, the great commission, snake-handling and poison-drinking), are absent from those manuscripts and are written in a different style of Greek — vocabulary and connective particles that read as a later hand's summary of resurrection material found elsewhere, most likely composed to give the Gospel a more conventional ending once its abruptness had become a problem for readers. A separate, shorter alternate ending also circulated. Nearly all modern critical editions therefore print 16:9–20 as a later addition, bracketed off, not as Mark's own text — this is a matter of manuscript evidence, not theological preference, and it is the near-consensus of textual critics across the theological spectrum, including conservative ones.

That leaves 16:8 itself: "καὶ ἐξελθοῦσαι ἔφυγον ἀπὸ τοῦ μνημείου, εἶχεν γὰρ αὐτὰς τρόμος καὶ ἔκστασις· καὶ οὐδενὶ οὐδὲν εἶπαν· ἐφοβοῦντο γάρ" — the last word is γάρ ("for"), a connective particle that normally does not end a sentence, let alone a book. Some scholars conclude the true ending was lost — a damaged final page, an unfinished draft — and point to the ending's grammatical oddity as evidence. Others, including many literary critics of Mark on his own terms, take the ending as deliberate: Mark's Gospel opens abruptly too (1:1, no birth narrative) and is full of characters who misunderstand, going right back to the disciples in 8:14–16, who "reasoned with one another, saying, 'It's because we have no bread'" (Mark 8:16) immediately after two feeding miracles they had just witnessed (8:5, 8) — Mark's narrative signature is human incomprehension in the face of what is right in front of them. An ending on fear and silence fits that pattern and throws the burden of proclamation onto the reader, since the women's silence is manifestly not final — the Gospel exists because someone spoke. Read as scripture, that trajectory — not a lost page — is the more persuasive account, though it is fair to note the question is not settled with certainty either way.

Mark 16:8 WEB

They went out, and fled from the tomb, for trembling and astonishment had come on them. They said nothing to anyone; for they were afraid.
