Why Everyone Should Believe that the Gospels are Reliable
If you've spent any time online debating Christianity, you've probably come across the claim that the Gospels are unreliable—perhaps even outright fabrications. The assumption behind this claim is simple: if the Gospels aren't trustworthy, then the case for Christianity crumbles. But is this true?
If the Gospels are historical, well-preserved, and rooted in real events, then the person at the center of them—Jesus Christ—deserves serious attention. In this article, we’ll explore why there are strong reasons to believe that the Gospels are, in fact, reliable.
1. Non-Christian Sources Confirm Key Gospel Events
One of the most overlooked facts in discussions about the Gospels is that several non-Christian sources confirm key details about Jesus and early Christianity. These sources, written by historians who had zero reason to promote Christianity, support major claims found in the Gospels.
Tacitus (c. 56–120 AD)
Tacitus, a Roman historian writing in the early 2nd century, is widely regarded as one of the most careful and reliable historians of antiquity. In his Annals (c. 116 AD), he records that:
"Christus [Christ], from whom the name [Christian] had its origin, suffered the extreme penalty during the reign of Tiberius, at the hands of one of our procurators, Pontius Pilate..." (Annals 15.44)
This not only affirms Jesus’s execution under Pontius Pilate—a key Gospel detail—but also demonstrates that Christianity had grown significantly in the decades following his death.
Pliny the Younger (c. 61–113 AD)
Pliny was a Roman governor who wrote a letter to Emperor Trajan around 112 AD asking for advice on handling Christians. He observed that Christians:
"were accustomed to meet on a fixed day before dawn and sing responsively a hymn to Christ as to a god."
This tells us that even in the early 2nd century, Christians worshiped Jesus as divine—a belief central to the Gospels.
Flavius Josephus (c. 37–100 AD)
Josephus, a Jewish historian, wrote about Jesus in Antiquities of the Jews (c. 93 AD), saying:
"At this time there was a wise man called Jesus, and his conduct was good, and he was known to be virtuous. And many people from among the Jews and the other nations became his disciples. Pilate condemned him to be crucified and to die."
While some later Christian interpolations exist in Josephus's writings, scholars widely agree that the core reference to Jesus is authentic.
Why This Matters
These independent sources—written by non-Christians hostile or indifferent to Christianity—confirm crucial Gospel claims:
✔ Jesus existed
✔ He was crucified under Pilate
✔ His followers rapidly grew after his death
✔ Christians worshiped him as divine
If the Gospels were complete fabrications, we wouldn’t expect external confirmation from people who had no stake in promoting them.
2. The Gospels Are the Best-Supported Texts of Antiquity
When people challenge the reliability of the Gospels, they rarely consider just how well-preserved these texts are compared to other ancient writings.
How Many Manuscripts?
The New Testament is backed by over 5,800 Greek manuscripts, with more than 25,000 copies in total across different languages. Compare this to other famous works:
Homer’s Iliad → 1,800 manuscripts (earliest copy: 400 years after it was written)
Plato’s Dialogues → 250 manuscripts (earliest copy: 1,300 years after original)
Caesar’s Gallic Wars → 251 manuscripts (earliest copy: 900 years after original)
The time gap between when the Gospels were written and our earliest surviving copies is only 30-100 years. That’s unheard of for an ancient document.
Why This Matters
If we doubt the reliability of the Gospels, we would have to throw out everything else from ancient history. No serious historian is willing to do that.
3. The Gospels Are Based on Eyewitness Testimony
One of the most compelling reasons to trust the Gospels is that they were written based on firsthand accounts.
The Role of Named Individuals
Richard Bauckham, in Jesus and the Eyewitnesses, argues that many names in the Gospels aren’t random—they represent living sources whom the early Christians could consult. Consider:
Simon of Cyrene (Mark 15:21) is named because his sons, Alexander and Rufus, were known to the early Christian community.
Bartimaeus (Mark 10:46) is specifically named, unlike other blind men Jesus healed, possibly because he was still around to verify the account.
Ancient biographies (like the Gospels) didn’t use footnotes, so naming sources was a way to show credibility.
Luke's Opening Statement
Luke starts his Gospel by emphasizing that he conducted an orderly investigation based on eyewitness accounts:
"Since many have undertaken to draw up an account of the things that have been fulfilled among us, just as they were handed down to us by those who from the first were eyewitnesses… I myself have carefully investigated everything from the beginning…" (Luke 1:1-3)
This is exactly what we would expect if Luke was writing history rather than myth.
4. The Gospels Are Internally Consistent (Yet Not Too Perfect)
Skeptics sometimes point to small differences between Gospel accounts as evidence of contradictions. But these variations actually strengthen their credibility.
The Mark vs. Matthew Example
Consider the sign on Jesus’s cross:
Mark 15:26: "The King of the Jews"
Matthew 27:37: "This is Jesus, the King of the Jews"
Luke 23:38: "This is the King of the Jews"
John 19:19: "Jesus of Nazareth, the King of the Jews"
The core message is the same—Jesus was crucified under the title “King of the Jews.” Minor wording differences reflect slightly different perspectives, as we would expect from real independent witnesses.
Why This Matters
If all four Gospels had word-for-word identical accounts, it would suggest collusion rather than authenticity. Instead, we see genuine agreement with expected variation, which is characteristic of truthful testimonies.
Conclusion: The Gospels Are Reliable
When we examine the evidence, the Gospels stand head and shoulders above other ancient texts in historical reliability.
External sources confirm key Gospel events.
The manuscript tradition is unparalleled in accuracy and number.
The Gospels rely on named eyewitnesses.
They contain natural variations expected in real historical accounts.
If we trust sources about Alexander the Great, Julius Caesar, or Plato, then we have far stronger reasons to trust the Gospels. And if the Gospels are true, then Jesus of Nazareth is exactly who He claimed to be.
That’s a claim worth taking seriously.
