I've begun creating a parallel-engine on the Gospel parallels as part of my larger project, and I thought I would share my foundational research with you all. This is a work in progress, and I'm always looking for feedback and suggestions.

Essentially the enter Biblical system and recount of Jesus can be reduced to Mark and Thomas. The others are derivations and expansions upon these two primary sources. The system below attempts to outline the flow of the documents and their relationships to one another.

Q Source (Lost Baseline) - c. 45 BCE

Peter's Oral Recollections (Mark's Foundation) - c. 50 CE

Thomas Fragments (Logos Sayings Stream) - c. 50 CE

J (Yahwist Source) - c. 950 BCE

  • Written in the Southern Kingdom of Judah.
  • Uses the name Yahweh.
  • Focuses on anthropomorphic depictions of God.

E (Elohist Source) - c. 850 BCE

  • Written in the Northern Kingdom of Israel.
  • Uses the name Elohim.
  • Focuses on prophets and abstract manifestations.

D (Deuteronomist Source) - c. 622 BCE

  • Discovered/written during the reign of King Josiah.
  • Focuses heavily on centralized worship in Jerusalem.

P (Priestly Source) - c. 550-450 BCE

  • Written during and immediately after the Babylonian Exile.
  • Focuses on genealogies, ritual law, Levitical codes, and cosmic order (like Genesis 1).

The Final Build: Around 450-400 BCE, Ezra the Scribe and his team took these distinct written scrolls and edited them into a single, seamless five-volume master ledger (The Torah).

The Old Testament

70 elders who ascended Mount Sinai with Moses (Exodus 24:9).

The Pure Sayings Stream (Q Engine)
The Eye-Witness Narrative Stream (Peter Engine)
The Visionary Offshoot Stream (Paul Engine)

First Generation Core

Q Source (Lost Baseline)

  • Pure Greek/Aramaic sayings list.
  • Apocalyptic/Galilean focus.

Peter's Oral Recollections

  • Direct eye-witness memories.
  • Grounded in Galilee dirt/houses.

Paul's Independent Epistles

  • Non-canonical narrative format.
  • Visionary/Cosmic theology.

First Derivative Output

Gospel of Thomas

  • Preserves raw sayings layout.
  • Shoved out of the official canon matrix.

Gospel of Mark

  • Written by Peter's scribe/disciple.
  • The primary chronological skeleton.

Independent track running parallel; feeds early church letters, not biographies.

Second Derivative Synthesis

Merged entirely into the downstream narrative builds below.

Gospel of Matthew

  • Anonymous Antioch Scribe.
  • Copies: Mark + Q Source.

Gospel of John

  • Did his own thing entirely.
  • Highly stylized metaphysical layer.

Third Derivative Synthesis

Merged entirely into the downstream narrative builds below.

Gospel of Luke

  • Gentile Physician/Researcher.
  • Copies: Mark + Q Source.

Parallel Cross-Section Grid

DESCRIPTOR: THE INVERSION OF AGE
THOMAS LOGION 4

"The man old in days will not hesitate to ask a small child seven days old about the place of life, and he will live. For many who are first will become last, and they will become one and the same."

MARK MK 10:15

"Truly I tell you, whoever does not receive the kingdom of God as a little child will never enter it."

MATTHEW MT 18:3

"Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven."

EDITORIAL NOTE: The evolutionary trajectory, the primitive Thomas node preserves the abstract formula (the 7-day child breaking covenant metrics). The downstream Synoptic nodes (Mark/Matthew) take the core idea and wrap it in a domesticated narrative setting ("little children").
