The Gospel of Mark Contains a Problem About Jesus Almost Nobody Notices | Neil deGrasse Tyson

Overview

Neil deGrasse Tyson argues that a close, text-by-text reading of the earliest Gospel—Mark—reveals a recurring pattern that “almost nobody notices” in popular Christianity. Specifically, Tyson claims that Mark:

• deliberately conceals key aspects of Jesus’s identity, and
• preserves a surprisingly “human” and theologically awkward portrait of Jesus that later Gospel writers smooth over.

---

1) Mark’s special status (why it matters)

Tyson emphasizes that Mark is treated as the earliest and most foundational Gospel for reconstructing how early Christians portrayed Jesus.

• Mark is the oldest canonical Gospel and a source for much of Matthew and Luke (Markan priority).
• Evidence Tyson cites includes:
  • Triple tradition similarities, where Matthew and Luke closely match Mark’s wording
  • Minor agreements, where Matthew and Luke sometimes align against Mark
  • “Harder readings,” where Mark often preserves the more theologically difficult statements, while Matthew/Luke tend to “smooth” them

Implication: Mark serves as an early written layer for evaluating how early Christians narrated Jesus—before later theological development.

2) The “Messianic secret” (systematic commands to silence)

Tyson highlights William Wrede’s (1901) idea that Mark repeatedly depicts Jesus commanding secrecy about:

• his identity (e.g., Messiah/Son of God)
• and the miracles he performs

Examples (as Tyson summarizes them) show a consistent pattern:

• Demons recognize Jesus → Jesus silences them
• Healings occur → Jesus tells recipients not to tell
• Disciples proclaim him → Jesus warns them to keep quiet, including until after the resurrection

Explanation Tyson reports: The secret functions as a literary/theological device that reconciles post-resurrection understanding (Jesus is clearly recognized as Messiah) with memories that Jesus did not publicly present himself as such during his ministry.

3) A “human Jesus” that later writers alter

Tyson argues that, when Mark is compared with Matthew and Luke, Mark contains multiple “hard” passages—moments where Jesus seems limited, emotionally volatile, or theologically inconvenient—and Matthew/Luke revise them toward a more divine Christology.

Key examples Tyson highlights:

• Emotion during healing (Mark 1:41): manuscript variants differ between Jesus acting with compassion vs anger; Matthew/Luke remove or soften the emotional detail.
• Miracle limitation (Mark 6:5): Jesus “could not” do miracles in Nazareth due to lack of faith; Matthew changes this to “did not,” shifting from inability to choice.
• Question of goodness (Mark 10:18): “Why do you call me good? No one is good except God alone” is interpreted as distancing Jesus from a divine attribute; Matthew modifies to reduce the implication.
• Limited knowledge (Mark 13:32): Jesus does not know the “day or hour.” Tyson notes this case as one of the few not softened.
• Gethsemane distress (Mark 14:33–36): Mark depicts Jesus as deeply distressed and troubled; Matthew softens it, while Luke intensifies it with angelic reinforcement and blood-like sweat imagery.

4) The family “insanity” episode (Mark 3:20–21)

Tyson spotlights Mark 3:20–21, where Jesus’s family tries to restrain him because they think he is “out of his mind.”

• Matthew and Luke omit this episode entirely.
• Tyson argues it is historically plausible under the criterion of embarrassment: tradition would be unlikely to invent such a troubling detail if Jesus were already viewed as fully divine.

---

5) Mark’s original ending: no resurrection appearances

Tyson calls this the most striking “documentary fact”:

• In the oldest and most reliable manuscripts, Mark ends at 16:8:
  • the women flee in fear
  • and they say nothing.
• The familiar longer ending (16:9–20)—which includes:
  • resurrection appearance episodes (e.g., to Mary),
  • the Great Commission,
  • and an ascension— is absent from the oldest manuscripts and considered a later addition.

Reasons given for the longer ending being later include:

• Vocabulary/style differences (many words don’t appear elsewhere in Mark)
• The content drawing from other Gospels’ resurrection traditions
• Tyson’s note that the longer ending includes unique claims (e.g., snakes, poison), suggesting it is a later supplemental compilation

Implication: The earliest Gospel announces resurrection belief but does not narrate resurrection appearances in its original form; later copyists/editors added them, apparently to address what communities felt was an incomplete account.

6) The resulting overall portrait of Jesus in Mark

Tyson’s “coherent picture” is that Mark presents Jesus as:

• beginning his ministry without a birth narrative or genealogy,
• marked by strong emotion, surprise, and sometimes genuine limitation,
• subject to a systematic concealment of identity during ministry,
• experiencing abandonment and horror at the end,
• ending with an empty tomb and terrified silence without appearances.

He contrasts this with later, more developed portrayals—especially John—where Jesus is depicted as far more divine, all-knowing, and fully in control.

7) The “problem” Tyson thinks people miss

Tyson concludes the issue isn’t that Jesus didn’t exist or that Mark is useless. Instead:

• Mark’s earliest, more human/weird/theologically difficult features are smoothed out by later harmonization and editing.
• Most readers never encounter Mark on its own terms, because they read harmonized versions or later additions.

---

8) Implications for how the Jesus tradition was constructed

Tyson argues the Gospels reflect developmental theological painting:

• The portrait of Jesus evolves from earlier to later communities.
• Matthew/Luke edit Mark toward a higher Christology.
• Later manuscript tradition adds resurrection material to match community needs.

He frames the Markan “problem” as a window into early tradition before full theological elaboration—especially because Mark preserves elements too embarrassing or awkward to remove cleanly.
