What Are the Gospels and Why Are There Four of Them?

New readers of the New Testament often ask a reasonable question early on: why do the four Gospels tell the same story four times? Would one careful account not have been simpler? The answer says something important about what these documents are and how they were meant to be read.

What the Word Gospel Means

Gospel translates the Greek euangelion, meaning good news or glad announcement. In the Roman world the word carried public, almost political weight: it was the kind of proclamation made when an emperor won a victory or an heir was born. Early Christians used it deliberately. Their announcement was that Jesus, crucified under Roman authority, had been raised and was Lord.

The word first described the message rather than the books. Only later did it come to name the four written accounts of Jesus’ life, teaching, death, and resurrection.

Four Accounts, Four Purposes

Each Gospel was written by a particular person for a particular community, and the differences are purposeful rather than accidental.

• Matthew writes with a Jewish audience in view. He quotes the Hebrew Scriptures constantly, opens with a genealogy tying Jesus to Abraham and David, and presents Jesus as the fulfillment of Israel’s hope and as a teacher greater than Moses.
• Mark is the shortest, fastest, and probably earliest. The narrative is urgent, heavy on action and light on discourse, and it presses hard on the question of Jesus’ identity and on the meaning of the cross.
• Luke writes as a careful researcher for a wider Greco-Roman readership. His account gives sustained attention to the poor, to women, to outsiders, and to prayer, and it continues directly into the book of Acts.
• John stands apart. Written last, it is reflective and theological, structured around a series of signs and the famous “I am” sayings, and it states its aim openly: that readers may believe.

The Synoptics and John

Matthew, Mark, and Luke are called the Synoptic Gospels, from a Greek phrase meaning “seen together,” because when placed in parallel columns they share a great deal of material, often in the same order and sometimes in nearly identical wording. Explaining that overlap is known as the synoptic problem. The dominant scholarly solution holds that Mark was written first, and that Matthew and Luke each used Mark alongside other material.

John is markedly different in structure, vocabulary, and content. As one analysis published by the University of Arizona’s Bible Interpretation project observes, there is far less verbal agreement between John and Mark than there is between Luke and Matthew, and John omits the parables and exorcisms while adding extended discourses found nowhere else. Whether John knew the earlier Gospels remains debated among scholars.

Why Four Accounts Help

The differences between the Gospels are sometimes presented as a problem. In practice they function more like witness testimony in any serious inquiry. Independent accounts of the same events that agreed word for word would suggest collusion rather than reliability. Accounts that agree on substance while differing in detail, emphasis, and sequence are what genuine testimony looks like.

The early church knew perfectly well that the four differed. In the second century Tatian produced a harmony that merged them into a single narrative, and the wider church declined to adopt it. Four accounts were kept, differences and all. That decision reflects a conviction that no single perspective exhausts the subject.

Historical study of these texts, such as Yale’s introduction to New Testament history and literature, treats those differences as evidence about the communities that produced them. Dale Martin’s opening lecture on how these writings moved from circulating stories into a recognized collection shows that all four were being read widely long before any formal list was drawn up.

Reading Them Well

Read each Gospel through on its own before comparing them. Ask what this particular writer emphasizes, what he includes that the others do not, and how he arranges his material. Then set them side by side. The composite picture that emerges is richer than any one account alone, which is precisely the point of keeping all four.
