Why would Jesus be baptized by John if baptism was connected with repentance?
This guide brings together several discussions already found across GodBlog. Rather than treating the question as a separate, simplified explanation of Jesus, it points readers toward the larger questions explored throughout the blog: what we can historically know about Jesus, how the Gospel writers shaped his story, how early Christians understood his identity, and how later Christian belief developed.
In this guide:
-
- Jesus and John the Baptist
- What historians think we can know about Jesus
- How the Gospels present Jesus differently
- The difference between the historical Jesus and the Jesus of faith
- How ideas about Jesus developed in early Christianity

Jesus and John the Baptist
The baptism of Jesus is an interesting place to begin because it belongs to both history and theology.
The Gospels give the event religious meaning, but historians also take Jesus’ connection with John the Baptist seriously.
In How Much Do We Know About the Historical Jesus?, GodBlog considers how little can be established with confidence about Jesus as a historical person. One of the events that receives relatively broad scholarly acceptance is that Jesus was baptized by John.
That makes the baptism especially useful for thinking about Jesus.
The event may be historically probable, but what it means depends upon how it is interpreted.
For Christian readers, it can mark the beginning of Jesus’ public mission. For historians, it is evidence that Jesus was connected with the religious world represented by John. For the Gospel writers, it becomes part of a much larger story about Jesus’ identity.

How much can we really know about Jesus?
Questions about the baptism quickly lead to a larger problem.
How much do we actually know about Jesus himself?
GodBlog returns to this question in Do We Really Know Anything About Jesus?.
There is an important difference between asking what Christians believe about Jesus and asking what historians can establish about him.
Christian faith makes claims about Jesus as the Son of God, Messiah, teacher, healer, crucified savior, and risen Christ. Historical investigation works differently. It asks what can reasonably be established from surviving evidence.
The baptism is therefore useful because it sits near the meeting point of these two approaches.
Something may have happened historically, while its religious significance developed through the way followers remembered and interpreted it.

The Jesus of history and the Jesus of interpretation
There has never been only one scholarly picture of Jesus.
Some writers emphasize Jesus as a Jewish teacher. Others understand him primarily as an apocalyptic prophet. Still others focus on his ethics, politics, religious message, or effect upon his followers.
GodBlog examines this problem more closely in The Quest for the Historical Jesus.
That discussion matters when reading the baptism story.
If Jesus is understood primarily as an apocalyptic Jewish preacher, his association with John may take on one meaning. If readers begin with later Christian doctrines about Jesus, the same event may take on another.
The event remains the same, but our interpretation of it can change according to the Jesus we believe we are looking for.

The Gospels are not identical accounts
Another reason the baptism deserves careful reading is that the Gospels do not simply provide four identical biographies.
Matthew, Mark, Luke, and John developed traditions about Jesus in different ways.
GodBlog discusses this larger issue in A History of the Bible. The article considers how the New Testament writings developed and why having four Gospels gives readers several perspectives rather than one perfectly uniform account.
This is important when interpreting any event in Jesus’ life.
Instead of combining every Gospel into a single version immediately, readers can first ask what each writer is trying to communicate.
Why does one writer emphasize a particular detail?
Why does another tell the story differently?
What does each version reveal about how early Christians were thinking about Jesus?
The baptism is not only an event to explain. It is also an opportunity to see how the Gospel tradition works.

Who did early Christians believe Jesus was?
The question becomes even larger when we move from what Jesus did to who Christians believed he was.
GodBlog explores the development of these ideas in How New Is the New Testament?.
Different New Testament writings emphasize different things about Jesus. Later Christian theology brought these ideas together into doctrines that became central to Christianity.
This matters to the baptism story because readers often approach the event with later beliefs already in mind.
If Jesus is understood from the beginning as divine and without sin, his baptism naturally creates a question:
Why participate in a practice associated with repentance?
The Gospel story can then be understood in several ways—as identification with others, acceptance of a mission, connection with John, or a public revelation of Jesus’ role.
But the larger issue remains worth exploring: how did early followers move from memories of a Jewish teacher to the theological understanding of Christ that later Christianity inherited?

Baruch Spinoza is experiencing something of a Renaissance, not his first. He goes in and out of fashion. I attribute the recent rebirth to Gilles Deleuze’s book, Spinoza: Practical Philosophy (1988), but so much has been written about Spinoza in the last several decades, and from such different perspectives, including neuroscience and feminism, that Deleuze could just be a part of a periodic eruption of interest. /1/ I return to Deleuze’s interpretation of Spinoza as a theorist of joy later. A lot depends on how one translates the Latin word for “joy.”
