What Is the Oldest Gospel?
The oldest complete gospel that survives is Mark, written around 65–75 CE. But 'oldest' hides three different questions: the oldest surviving book (Mark), the oldest gospel material (the reconstructed sayings source Q, and — on some scholars' dating — the earliest layer of the Gospel of Thomas), and the oldest physical object (Papyrus 52, a scrap of John copied around 125–175 CE). Here are all three answers, with what's certain and what's argued.
Three different questions
“Oldest gospel” can mean the oldest book that survives complete, the oldest gospel material — sayings and stories that circulated before any surviving book — or the oldest physical manuscript you could hold. The three answers are different, and most confusion on this topic comes from mixing them. Taken in order:
The oldest surviving gospel: Mark
The scholarly majority, from the nineteenth century to today, holds that Mark was written first among the canonical four — usually dated around 65–75 CE, within living memory of the events and close to the Jewish War. The case (Markan priority) is cumulative: Matthew and Luke reproduce most of Mark's content, generally follow his order, and smooth his rough Greek — edits that make sense in one direction only. Matthew and Luke follow in the 80s–90s, John around 90–110. No serious contender for “oldest complete gospel” exists outside these four; the non-canonical gospels that survive whole are second century or later.
The oldest source: Q
Behind Matthew and Luke, most scholars detect a second shared source: roughly 230 verses of sayings — the Lord's Prayer, the Beatitudes, “love your enemies” — that both contain but Mark lacks, often in near-identical Greek. The reconstruction is called Q, and if the hypothesis is right, it was compiled in the 40s–60s CE — earlier than Mark, within a generation of Jesus. Q is a scholarly reconstruction, not a discovery: no manuscript exists, and a minority of scholars (following Austin Farrer and Mark Goodacre) dispense with it by having Luke read Matthew. We serve Mattison's translation of the reconstructed Q with exactly that label — a reconstruction, honestly marked, cited by its conventional Lukan versification.
Q's deepest interest for this library: it is a sayings gospel — the same genre as Thomas. The genre the canon preserved only inside narratives, the buried library preserved straight.
The wildcard: Thomas
The Gospel of Thomas is where the dating fight gets interesting. Roughly half its 114 sayings parallel the synoptics; the parallels are often less developed than the canonical versions, which scholars like Helmut Koester and Stephen Patterson read as marks of independence and early tradition — an earliest layer plausibly from 50–70 CE. Others, such as Simon Gathercole and Mark Goodacre, find traces of Matthew's and Luke's editing inside Thomas and date it to the early second century. The honest summary: the book of Thomas is probably younger than Mark; some of its sayings may be as old as anything Christianity preserved. Read it complete and judge the texture yourself.
The oldest physical fragments
Ink and papyrus tell their own story. The oldest generally accepted gospel manuscript is Papyrus 52, a fragment of John's trial scene the size of a credit card, commonly dated c. 125–175 CE. From outside the canon: the three Greek fragments of Thomas from Oxyrhynchus (c. 200 CE), and the Egerton Gospel — an otherwise unknown gospel whose papyrus, copied in the late second century, is among the very oldest Christian books of any kind. That an unknown gospel sits in the oldest tier of surviving Christian manuscripts is the quiet headline of this whole question: the early gospel world was bigger than four.

Common questions
Which gospel was written first?
Among the four canonical gospels, Mark — most scholars date it around 65–75 CE, with Matthew and Luke drawing on it in the 80s–90s and John around 90–110 CE. That majority position (Markan priority) rests on how Matthew and Luke track Mark's wording and order.
Is the Gospel of Thomas older than the four gospels?
Contested. Some scholars argue its earliest sayings layer is independent of the synoptics and could reach back to 50–70 CE; others date the whole work to the early second century and see synoptic dependence. A common middle view: composed across 60–140 CE with some genuinely early tradition inside it.
What is the Q source?
Q (from German Quelle, 'source') is the hypothesized collection of Jesus' sayings that Matthew and Luke both used alongside Mark — reconstructed from the material they share that Mark lacks. If the hypothesis is right, Q predates both, putting it in the 40s–60s CE. No manuscript of Q has ever been found.
What is the oldest physical gospel fragment?
Papyrus 52 (P52), a credit-card-sized scrap of the Gospel of John usually dated around 125–175 CE. Among non-canonical texts, the Greek fragments of Thomas from Oxyrhynchus date to around 200 CE, and the Egerton Gospel papyrus to the late second century.
