This article presents what each major source claims, where those claims converge, where they conflict, and what is uncertain. The goal is clarity, not partisanship.

The Twelve in Christian Tradition

Christian texts report that Jesus chose twelve named apostles. Gospels titled Mark and Matthew provide lists that substantially agree, the Gospel traditionally titled ‘Luke’ lists their names (Luke 6:12–16). The work traditionally titled ‘Acts of the Apostles’ reports that Matthias was chosen to replace Judas Iscariot after Judas’ death (Acts 1:21–26). Acts is the narrative sequel to Luke in early Christian tradition. The number twelve likely also carries symbolic meaning that recalls the twelve tribes of Israel.

“Twelve” is more than a headcount. In Israel’s scriptures (the Jewish Tanakh, called the Old Testament in most Christian Bibles; here “Israel” means the ancient biblical people, not the modern state) the nation is structured around twelve tribes descended from Jacob, who is also called Israel (Genesis 32:28; 35:10). Jacob’s sons are Reuben, Simeon, Levi, Judah, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, Joseph, and Benjamin. Lists sometimes differ for practical reasons. Levi is set apart for priestly service and does not receive a land allotment, and Joseph is often counted through his sons Ephraim and Manasseh so the total remains twelve in land distributions. That background explains why the Gospels present Jesus choosing twelve named disciples. The number signals a reconstitution of Israel around him, not an arbitrary team size. The texts make the symbolism explicit. Jesus promises the Twelve they will sit on twelve thrones judging the twelve tribes of Israel (Matthew 19:28) and gives them a share in his kingdom (Luke 22:28–30). In Bible language, “judge” means to govern or exercise authority, not only to hold a courtroom. The New Jerusalem is pictured with twelve gates named for the tribes and twelve foundations named for the apostles (Revelation 21:12–14). Luke–Acts reinforces the point by restoring the group to twelve before Pentecost when Matthias replaces Judas (Luke 6:12–16; Acts 1:21–26). Biblical lists of tribes vary in some passages for literary or symbolic reasons, for example Revelation 7 omits Dan and lists Joseph in place of Ephraim, yet the theological point stays the same: “twelve” denotes the fullness of Israel. The apostles do not map one-for-one to tribal names. They function as a representative leadership for Israel renewed around Jesus. Christian tradition connects the Twelve apostles with the twelve tribes of Israel as a symbol of Israel renewed while the Qur’an connects “twelve” to the Children of Israel only, twelve tribes and twelve leaders. It does not connect Jesus’s disciples to the number twelve or to the twelve tribes. It refers to them simply as al-hawariyyun without giving a number.

Names in the canonical lists

Peter (Simon Peter or Cephas), Andrew, James son of Zebedee, John son of Zebedee, Philip, Bartholomew, Matthew (Levi), Thomas (Didymus), James son of Alphaeus, Thaddaeus (Judas son of James), Simon the Zealot, Judas Iscariot. Matthias is added in Acts 1 to replace Judas.

While the Gospels titled Matthew, Mark, and Luke as well as Acts provide lists of the Twelve apostles by name, the Gospel of John refers several times to “the Twelve” as a group , but never actually lists all their names together. This difference shows that John assumes knowledge of the group but does not present a formal roster like the Synoptic Gospels.

When Christianity began in the first century, it was not a single, unified movement. The followers of Jesus came from different backgrounds, spoke different languages, and carried different ideas about who He was and what His message meant. Without a fixed New Testament, each community relied on its own traditions, oral teachings, and written accounts. These differences led to the rise of multiple sects, each claiming to represent the true faith.[1]

The first two centuries were a time of theological experimentation and sharp disagreement. Some groups held tightly to Jewish law, while others rejected it entirely. Some emphasized mystical knowledge, while others insisted on the authority of the apostles. These early divisions set the stage for the later formation of the New Testament canon and the definition of “orthodox” Christianity.[2]

The Apostolic Period (c. 30–70 CE)

According to Christian tradition, Jesus appointed twelve close followers called apostles during his ministry. These Twelve were considered His primary messengers, sent to preach and continue His work after His departure. In Christian belief, they included Peter, John, and others, but not Paul.

Historians agree Jesus had a core group of disciples, but the specific number “twelve” and the event of formally appointing them come only from Christian sources written decades later. No contemporary non-Christian historical records confirm the selection of the Twelve. What these apostles originally taught about Jesus is also known only from Christian tradition, which presents them as proclaiming Him the Messiah and Son of God. Islamic sources, by contrast, refer to Jesus’ close followers as al-hawariyyun, faithful supporters who recognized Him as a prophet and messenger of Allah, without assigning Him divinity.

The earliest Christians were those who had seen Jesus or learned directly from these apostles. The central leadership of the early movement was in Jerusalem, under James (called “the brother of the Lord” in Christian texts), along with Peter and John.[3] The movement at this stage remained closely tied to Judaism, observing the Law of Moses while proclaiming Jesus as the Messiah.[4]

Paul, originally a Pharisee who persecuted early followers, later became a Christian missionary. Unlike the Twelve, he claimed apostleship based on a vision of the risen Jesus after His death. His missionary work brought a new challenge: many Gentiles were joining the faith, and Paul argued they should not be required to follow the full Jewish law. This caused tensions with Jewish Christians who believed the Law remained binding.[5] These disputes are recorded in the New Testament itself, especially in Galatians 2 and Acts 15, which describe debates between Paul and the Jerusalem leadership about circumcision and the Law.[6]

The destruction of the Jerusalem Temple by the Romans in 70 CE marked a turning point. The center of authority in Jerusalem collapsed, and leadership shifted to other cities like Antioch, Rome, and Alexandria.[7] Without the unifying presence of the original apostles, local churches began developing distinct beliefs and practices.

Diversity After the Apostles (c. 70–100 CE)

After the death of the apostles, Christian communities had to preserve the teachings of Jesus without a universally agreed set of writings.[8] Different regions produced and used different gospels and letters.[9] Oral tradition was still powerful, but the message varied from place to place.

This period saw the emergence of movements that emphasized different aspects of Jesus’ life and message. Some still identified strongly with Judaism, while others broke away entirely. The seeds of later heresies were already being planted, as outside philosophical and religious ideas began influencing Christian thought.[10]

Major Sects and Movements in the First Two Centuries

Jewish-Christian Sects

These groups saw themselves as the true heirs of Jesus’ mission, keeping the Mosaic Law while believing in Him as the Messiah.

1. Nazarenes : Accepted Jesus as the Messiah, observed the Law, and used the Hebrew Scriptures along with certain gospel traditions.[11]

2. Ebionites : Rejected the divinity of Jesus, viewing Him as a human prophet chosen by God. They upheld strict Torah observance and rejected Paul as an apostate from the Law.[12]

Gnostic Groups

Gnosticism was a broad religious movement that blended Christian language with mystical and philosophical ideas. It often taught that the material world was created by a lesser deity and that salvation came through secret spiritual knowledge.[13]

1. Sethians : Wove elaborate mythologies about divine beings, the creation of the world, and the role of the biblical figure Seth.[14]

2. Valentinians : Founded by Valentinus, they used Christian terms but gave them symbolic meanings drawn from Gnostic cosmology. They had their own gospel interpretations and a spiritualized view of salvation.[15]

In the early centuries after Jesus, different Christian communities produced many writings about his life, teachings, and followers. Some of these writings focused on sayings of Jesus. Others described events not found in the New Testament. A few presented completely different views about who Jesus was and what his message meant.

Today, the New Testament contains four gospels: Matthew, Mark, Luke, and John. These were not the only ones written. Dozens of other gospels once existed. They were shared, copied, and read in Christian circles before the church finalized the canon. These writings are now called non-canonical gospels because they were eventually left out of the Bible.

This article introduces the major non-canonical gospels, explains what they contain, and notes when they were written. It does not analyze why they were accepted or rejected. That will be the focus of a separate article.

What Is a “Non-Canonical” Gospel?

The word canon refers to the official list of books accepted as scripture. A non-canonical gospel is any gospel not included in the New Testament.

These writings are still called “gospels” because they tell stories or teachings related to Jesus. The title “gospel” does not always mean a narrative account like the four canonical gospels. Some are dialogues, homilies, theological treatises, or sayings collections. A few contain only fragments. Others focus on Jesus’s family or events in his childhood. Some present entirely new interpretations of his death and resurrection.

How Many Gospels Existed?

Scholars have identified more than 30 gospels that circulated among early Christians. Some survive only in fragments. Others are mostly intact. Most were written between the mid-1st century and the 3rd century.

We know about these gospels from two main sources:

1. Ancient manuscripts discovered in places like Egypt, especially the Nag Hammadi library in 1945.

2. Quotations and summaries in the writings of early church fathers who often mentioned them to criticize or refute them.

Not all of these writings were intended as factual history. Some were symbolic or mystical. Others were written by Christian sects with beliefs that differed from the emerging orthodoxy of the later church.

In the New Testament, there are four gospels that Christians have accepted from the very beginning. Although many early gospels circulated among Christian communities, only these four eventually became widely accepted. These books were not written during Jesus’s lifetime. They were composed decades later, with Mark around 60–70 CE, Matthew around 70–85 CE, Luke around 80–90 CE, and John around 90–100 CE. The original manuscripts do not name their authors, and modern scholars agree that these texts were not written by eyewitnesses. The acceptance of these four gospels by early Christian communities was influenced not only by their connection to apostles but also by their theological alignment with emerging church doctrines.

The word disciple means a follower or student. Jesus had many disciples who followed him, listened to his teaching, and tried to live by it. From among those followers, he chose twelve men for a special mission. These twelve are called the apostles. According to Christian belief, the apostles witnessed Jesus’s teachings, his miracles, and his resurrection. Early church tradition later connected each of the four gospels to an apostle or someone who knew an apostle, and this traditional connection is one reason they were accepted, even though modern scholarship does not confirm direct authorship by those individuals.

The names of the twelve apostles, as listed in the New Testament, are: Peter (also called Simon), Andrew, James son of Zebedee, John son of Zebedee, Philip, Bartholomew, Matthew (also called Levi), Thomas, James son of Alphaeus, Thaddaeus (also called Judas son of James in some lists), Simon the Zealot, and Judas Iscariot. After Judas Iscariot’s betrayal and death, Matthias was chosen to replace him.

When we say “The original manuscripts do not name their authors, and modern scholars agree that these texts were not written by eyewitnesses,” here is exactly what that means.

If you look at the earliest copies of these gospels, nowhere inside the text does it say, I, Matthew, wrote this or I, John, am giving you my eyewitness account. The writings start straight into the story without identifying who wrote them. The titles we see today like The Gospel According to Matthew or According to Luke were added later by early church tradition, not by the authors themselves.

Modern scholars across the board confirm this. For example:

Bart Ehrman writes: “The Gospels are all anonymous. Their titles—‘According to Matthew,’ ‘According to Mark,’ and so on—were added later.” (Jesus, Interrupted, p. 146)

Helmut Koester explains: “The oldest manuscripts of the Gospels have no names attached. The ascriptions to Matthew, Mark, Luke, and John were given by tradition.” (Ancient Christian Gospels, p. 35)

Raymond Brown also states: “The Gospel titles do not come from the authors themselves but from second-century church tradition.” (An Introduction to the New Testament, p. 158)

Because of this, scholars agree that these writings were not produced by identified eyewitnesses but by unknown authors within early Christian communities who were passing on the traditions they had received.

There is also the issue of timeline. Jesus’s ministry ended around 30 to 33 CE, yet the earliest gospel, Mark, was not written until around 60 to 70 CE, decades later. Matthew, Luke, and John came even later, up to 90 or 100 CE. That long gap means these writings were not made during the events but after years of oral tradition in different communities. By then, most original eyewitnesses would no longer have been alive. On top of that, the gospels themselves sometimes show differences in the order and timing of events, indicating the authors were not recording history like modern journalists but shaping stories and teachings they had received. This timeline is one key reason historians do not see the gospels as direct eyewitness reports.

What Christians Traditionally Believe and What Scholars Have Found

Most people grow up assuming December 25th is the birthday of Jesus. Churches hold celebrations, families decorate Christmas trees, and almost every Christian household marks this as a holy day. However, when we take a step back and look at what the Bible says, what the Qur'an says, and what historical records show, things start to look very different. The truth is, Jesus was not born on December 25th. That date was not chosen by Jesus, his disciples, or by any verse in the Bible. It came from Roman politics, not divine instruction.
