Who’s Who in Early Christian History: James, the Brother of Jesus

The latest installment of the "Lives Remembered" series by Shirley Paulson

James occupies a unique place in early Christian history. He was neither the best-known disciple nor the most prolific writer. He did not travel the Mediterranean like Paul, nor did he leave behind a Gospel bearing his name. Yet after Jesus’ death, he emerged as the principal leader of the Jerusalem community.

However, it’s his relationship with his brother, Jesus, that remains so intriguing, and that memory is what fascinates me.

What would it have been like to be the brother of Jesus? James—often remembered as James the Just—is the closest historical figure who invites us to reflect on that question.

Scholars have long debated exactly how Jesus and James were related. Were they biological brothers? Was James an older half-brother from an earlier marriage of Joseph? Were they cousins? Or did the earliest Christians use the word “brother” in a broader sense that reflected family, community, or shared faith? Every position has thoughtful defenders, and the historical evidence is unlikely ever to settle the question. The precise biological relationship is not the most interesting one.

When we trace the many memories of James preserved in early Christian writings, a more nuanced picture begins to emerge. Again and again, Christians remembered him as someone who shared Jesus’ deepest commitments, understood his vision, and carried it forward after his death. More than historical information, their writings preserve an unexpected mutual respect.

An Unlikely Beginning

The earliest memories of James begin, somewhat surprisingly, with skepticism. The Gospels suggest that Jesus’ own family struggled to understand his public ministry. Mark tells us that members of his family attempted to restrain him because they believed he was “out of his mind.” John’s Gospel remarks just as bluntly that even Jesus’ brothers did not believe in him. Then, almost without explanation, everything changes.

After Jesus’s death—according to 1 Corinthians (15:7)—Jesus “appeared to James, then to all the apostles.” Whatever James had once believed about his brother, this resurrection encounter marked a decisive turning point.

Within only a few years, James had become one of the acknowledged leaders—or “pillars,” (Galatians 2:9)—of the Jerusalem community. It is one of the most remarkable transformations in the New Testament. The skeptic becomes the leader.

James the Just

As James emerges into history, he does so not as someone who abandoned Judaism but as someone deeply devoted to it. Known as James the Just by ancient writers, he appears to have lived a life of rigorous prayer, devotion, and concern for faithful observance of the Torah. Seeking to live its deepest values, James recognized something new but consistent with his Jewish life had begun through Jesus.

That balance became especially important when increasing numbers of non-Jewish believers joined the movement. According to Acts, the question about whether or not Gentile followers of Jesus should be circumcised and observe full Mosaic Law reached its climax around the year 49 CE. James may have offered the concluding judgment that Jewish and Gentile followers of Jesus should be able to share life together, but that Gentiles would not be required to become Jewish before joining the community.

James’s relationship with Paul has often been described as a sharp theological conflict, especially because Paul’s letters emphasize justification by faith while the Letter of James famously insists that “faith without works is dead.” More recently, however, scholars see the situation differently. Paul and James were addressing different problems. Paul opposed those who insisted Gentiles must become Jews in order to belong to God’s people. James challenged the community members whose faith had become disconnected from compassion and care for others. Their emphases differed, but both assumed that authentic faith transforms the way people live.

As the decades passed, Christians continued to write about James. The memories differ in detail, yet together they reveal something surprisingly consistent about the kind of brother to Jesus they believed James had become.

Remembering James

As Christian communities spread throughout the Mediterranean world, they continued to write about James—imagining conversations with him and picturing him at decisive moments in Jesus’ life. These memories reveal what people cherished, what later generations found admirable, trustworthy, and worth passing on.

One of the earliest of these memories appears in the Infancy Gospel of James. Although the work is primarily concerned with the birth and childhood of Mary, it also presents James as an older son of Joseph from an earlier marriage—therefore, a half-brother to the infant Jesus. The historical claim is unlikely, but significantly, James is remembered as part of a loving family surrounding the arrival of Jesus. It is a gentle memory, not one of rivalry or competition but of shared family life.

Another community remembered James entirely differently. In the Gospel of Thomas, the disciples ask Jesus who will lead them after he is gone. Jesus answers with surprising directness: “Go to James the Just.” The statement goes even further, declaring that “for his sake heaven and earth came into being.” This is probably not a historical quotation. It is poetic, extravagant praise. Yet beneath the hyperbole lies an unmistakable conviction. This community remembered James as the one whom Jesus himself trusted to continue his work.

Other writings remember James less as an administrator and more as a conversation partner.

In the Apocryphon of James, Jesus appears after his resurrection and draws James aside for a private conversation. Peter is present as well, but James consistently emerges as the more perceptive listener. He asks thoughtful questions, listens carefully, and grasps the deeper meaning of Jesus’ teaching. The point is not that James possessed information hidden from everyone else; he is the one who understood.

The same theme appears in two other writings that focus on James’ final days.

The First Apocalypse of James imagines Jesus in a post-resurrection scene, preparing James for his own coming martyrdom. At one point Jesus tells him, “You are not my brother materially.” In a deeply moving way, Jesus is not denying their relationship; he is assuring James that what they share cannot be measured by physical kinship alone. Their shared understanding, their shared purpose, and their shared trust in God reach beyond the limits of earthly life.

The Second Apocalypse of James continues that memory. James stands before hostile crowds, proclaims what he has learned from Jesus, and faces death with remarkable composure. The emphasis is not on his suffering itself but on his unwavering confidence that the life Jesus revealed cannot be destroyed. Even in martyrdom, James is remembered as someone whose deepest relationship with Jesus remains intact.

James is remembered as the brother who understood, even when other struggled to see it. He understood the responsibility of leadership. And when his own life was threatened, he understood that faithfulness matters more than survival.

That portrait sheds light on the New Testament Letter of James. How much James was involved in the writing of this letter remains an open scholarly question. Yet the author presents a figure who sounds remarkably like the James remembered elsewhere: practical rather than speculative, compassionate toward the poor, deeply concerned with integrity, and thoroughly shaped by Jesus’ teaching.

Its many echoes of the Sermon on the Mount suggest someone who had listened carefully—not simply to Jesus’ words, but to the life those words called forth. Across centuries of Christian memory, James is consistently portrayed as someone who shared Jesus’ vision so completely that later generations could scarcely imagine one without the other. Whatever their biological relationship may have been, Christians remembered a bond built on mutual understanding, shared devotion, and a willingness to carry the same work into the world.

More Than Family

The many memories of James do not eliminate the historical questions surrounding his life. If anything, they remind us how much remains uncertain. Again and again, Christians remembered James not simply because he belonged to Jesus’ family but because he belonged to Jesus’ life.

He appears as the trusted leader who carries forward Jesus’ work. He listens when Jesus speaks. Jesus, in turn, entrusts him with responsibility, encourages him in moments of fear, and prepares him for the suffering that lies ahead.

The writings differ in date, place, theology, and literary style. Some tell imaginative stories. Others preserve remembered sayings. None allows us to reconstruct the daily conversations between Jesus and James. Yet together they preserve something that later Christians found too beautiful to lose. They remembered a relationship marked by trust; a relationship shaped by shared purpose; and two lives that had become deeply intertwined.

Jesus himself is remembered as redefining family. When told that his mother and brothers were looking for him, he answered that those who do the will of God are his true family. He was not dismissing his relatives. He was expanding the meaning of kinship. James is the kind of brother Jesus hoped for: the one who walked with him, learned from him, and faithfully carried forward the work they shared.
