Question
Does the earliest major manuscript evidence include Mark 16:9-20, the passage commonly called the longer ending of Mark?
Short Answer
Not in two of the most important surviving fourth-century Greek codices.
Codex Sinaiticus and Codex Vaticanus end the continuous text of Mark at 16:8 rather than continuing with verses 9-20. In the digital Codex Sinaiticus, the physical page can be inspected directly: Mark 16:1-8 is followed by the subscription to Mark and then the beginning of Luke.
That is important evidence, but it is not the whole history of the passage. Mark 16:9-20 is ancient, is preserved in many manuscripts, and became a familiar part of the transmitted Gospel of Mark.
The responsible conclusion is therefore more precise than either "the verses were always there" or "the verses have no ancient textual history." The manuscript tradition contains a genuine variant at the ending of Mark.
Primary Evidence
The most direct evidence is the manuscripts themselves.
Codex Sinaiticus is a fourth-century Greek parchment codex. Its surviving New Testament contains the complete Gospel of Mark. On the page where Mark ends, the text proceeds through Mark 16:8. The manuscript then gives the subscription identifying the end of Mark, and the Gospel of Luke begins on the same page.
The Codex Sinaiticus Project provides both the manuscript image and a transcription of this page.
Source: Codex Sinaiticus, Mark 16:1-8 followed by Luke 1:1.
Codex Vaticanus, another major fourth-century Greek parchment codex, likewise does not contain Mark 16:9-20 as the continuous ending of Mark.
The agreement of these two old and extensive witnesses is a major reason the longer ending receives close attention in modern textual criticism.
What Codex Sinaiticus Actually Shows
The Sinaiticus evidence is unusually accessible because the manuscript can be viewed online.
The final page of Mark preserves the women coming to the tomb, the announcement that Jesus has risen, and the instruction concerning Galilee. The continuous text reaches the statement in Mark 16:8 that the women were afraid.
Then Mark ends.
This means that the omission of verses 9-20 in Sinaiticus is not inferred merely from a modern printed edition. It is visible in the surviving manuscript.
The Codex Sinaiticus Project generally dates the manuscript to the fourth century, sometimes more specifically to the middle of that century.

The Variant
The textual question is not whether Mark has a resurrection account.
Mark 16:6, before the disputed longer ending, reports the announcement concerning Jesus: he has been raised and is not in the tomb.
The textual question is what followed Mark 16:8 in the earliest recoverable form of the Gospel.
One manuscript tradition ends at 16:8. Another transmits the familiar longer ending in verses 9-20. The broader textual tradition also contains evidence of other ending forms.
That makes the ending of Mark a particularly clear example of why manuscript evidence must be examined rather than hidden.
The Longer Ending Is Ancient
The absence of Mark 16:9-20 from Sinaiticus and Vaticanus should not be confused with a claim that the longer ending was invented in modern times or appears only in very late Bibles.
It has an ancient transmission history.
Scholarly discussion of the passage has long recognized both sides of the evidence: early major manuscripts without the longer ending and ancient evidence for knowledge and use of material from the longer ending.
This is precisely why the passage is a textual variant rather than a simple case of discovering a modern printing mistake.
Why Age Matters, but Does Not Decide Everything
Sinaiticus and Vaticanus are important because they are early, extensive witnesses.
But textual criticism does not use the rule "oldest surviving manuscript automatically wins."
A physical manuscript has a date. A reading within it has a transmission history that may be older than the surviving copy. Conversely, an old manuscript can contain a reading that arose after another reading.
Researchers therefore compare external evidence such as manuscript age, geographical distribution, and relationships among witnesses with internal evidence concerning the competing readings.
For Mark 16, the fourth-century evidence is especially significant because two major codices independently preserve Mark without verses 9-20 as its continuous conclusion.
What the Evidence Does Not Mean
The variant does not erase the resurrection from Mark.
Before the point where the textual dispute begins, Mark 16:6 already contains the announcement that Jesus has risen.
The variant also does not establish that everything stated in verses 9-20 is historically false. Textual criticism asks whether wording belonged to a particular textual form or stage. Historical and theological evaluation are related but separate questions.
Finally, the evidence does not justify pretending the longer ending has no manuscript history. It does. A complete study must acknowledge both its widespread transmission and the significant witnesses that lack it.
Translation Decisions
Modern Bible translations handle Mark 16:9-20 in different visible ways.
Many print the passage while marking it with brackets, a heading, or a footnote explaining that some early manuscripts do not contain it. The exact editorial presentation belongs to the translation or edition.
That is a useful distinction.
A manuscript is a physical witness. A critical edition evaluates witnesses. A translation then makes editorial decisions about how to present the resulting textual question to readers.
Those three levels should not be collapsed into one.
Theological Implications
The ending of Mark is sometimes treated as though the Christian claim of Jesus' resurrection depends upon verses 9-20.
The manuscript evidence does not support framing the issue that way.
Even the form of Mark ending at 16:8 includes the empty tomb and the announcement that Jesus has been raised. The resurrection is also independently present throughout the other New Testament writings.
The textual question should therefore be allowed to remain a textual question: what ending is supported by the earliest recoverable manuscript evidence for Mark?
Christian theology does not become stronger by concealing a textual variant. It is better served by stating exactly what the manuscripts preserve.
Conclusion
Mark 16:9-20 is one of the clearest large textual variants in the New Testament manuscript tradition.
Codex Sinaiticus and Codex Vaticanus, two major fourth-century Greek witnesses, do not contain verses 9-20 as the continuous ending of Mark. In Sinaiticus, the surviving page itself shows Mark ending at 16:8 before Luke begins.
At the same time, the longer ending is ancient and became widely transmitted.
The strongest evidence-based conclusion is therefore:
The earliest major complete Greek witnesses provide strong evidence for a form of Mark ending at 16:8, while Mark 16:9-20 has its own ancient and extensive transmission history.
That conclusion neither hides the variant nor asks the manuscripts to prove more than they can.
