One of the most intriguing and debated questions in Christian theology is the existence and identity of Jesus' brothers.

The Bible mentions the “brothers of Jesus” several times, but who were these people?
This article aims to clarify this enigmatic question by exploring what the New Testament tells us about these characters.
The Concept of 'Brother' in Scripture
Before going into the details, it is important to understand that the concept of 'brother' in biblical times was not necessarily the same as what we understand today.
The Greek term 'adelphos', translated as 'brother', could refer to blood brothers, but also to half-brothers, cousins or even close members of a community.
This nuance is important for understanding the controversy over the identity of Jesus' brothers, as well as for understanding other aspects of Jesus' life, such as #"The Birth of Jesus"#.
Who are mentioned as Jesus' brothers?
The New Testament, particularly in the books of Matthew and Mark, mentions four individuals as being brothers of Jesus: James, Joseph (or Joses), Judas, and Simon.
In addition to them, Jesus' 'sisters' are also mentioned, but, unlike the brothers, their names are never made explicit.
James – The Leader of the Church in Jerusalem
James, also known as James the Just, is perhaps the most famous of Jesus' brothers.
He is often cited as the leader of the Church in Jerusalem after the death and resurrection of Jesus.
James was known for his piety and commitment to Jewish law, which earned him the nickname “the Just.”
He is also considered the author of the New Testament Epistle of James.
Joseph (or Joses) – The Silent Brother
Joseph, also known as Joses, is another figure mentioned as Jesus' brother. Unfortunately, little is known about him, as references to Joseph in the scriptures are brief and few.
Still, as a member of Jesus' family, he likely played a significant role in the early Christian community.
Judas (or Judas Thaddeus) – The Saint of Lost Causes
Judas, who must be distinguished from Judas Iscariot, the disciple who betrayed Jesus, is another brother mentioned.
He is referred to in some translations as Judas Thaddeus or Lebeus.
He is traditionally believed to be the author of the Epistle of Jude, one of the books of the New Testament.
In several Christian traditions, Jude Thaddeus is venerated as a saint, being popularly known as the “saint of lost causes”.
Simon – The Zealot
Simon, who is also called Simon the Zealot, is the fourth brother of Jesus mentioned in the New Testament.
The term “Zealot” was used to identify members of a Jewish movement that strongly resisted Roman influence in Israel.
Unfortunately, information about Simon is limited, and his specific role in the early church is largely unknown.
The Controversy of Jesus' Brothers
There is significant debate among different Christian traditions about the exact relationship of these brothers to Jesus.
Catholic tradition, for example, supports the doctrine of the Perpetual Virginity of Mary, arguing that these “brothers” were actually close relatives of Jesus, possibly cousins.
On the other hand, many Protestant traditions interpret these characters as literal brothers of Jesus, sons of Mary and Joseph.
Conclusion
Although scripture is sparse on details about Jesus' brothers, what can be concluded is that these figures—James, Joseph, Judas, and Simon—played notable roles in early Christianity.
Their closeness to Jesus gave them an intimate perspective on his ministry and teachings.
While the exact nature of his relationship to Jesus remains a matter of debate, his influence on the trajectory of Christianity is undeniable.
