Titles of Jesus in the synoptic gospels and selected 'I am' sayings in John

What you'll learn

• How the titles Messiah, Son of God and Son of Man work in the synoptic gospels.
• How John’s selected “I am” sayings present Jesus through rich Jewish symbolism.
• Why Old Testament background is essential for interpreting Jesus’ identity.
• How different understandings of Jesus shape Christian ethics, law and wider society.

Starting point: what is a “title” of Jesus?

A title is more than a nickname. In the Gospels, titles such as “Messiah” or “Son of God” are theological claims about who Jesus is and what his mission means.

The synoptic gospels are Matthew, Mark and Luke. They are called “synoptic” because they can be “seen together”: they share many stories, structures and sayings. John’s Gospel is different in style and theology, especially in its long symbolic speeches and “I am” sayings.

The titles are easiest to understand as a map of Jesus’ identity.

Messiah / Christ

In the Old Testament, messianic hope is linked especially with the line of David. Key background texts include 2 Samuel 7, where God promises David an enduring dynasty, and Psalm 2, where the king is described as God’s anointed.

In the synoptic gospels, Jesus is recognised as Messiah, but the title is redefined. Peter confesses Jesus as the Messiah in Mark 8:29, but Jesus immediately teaches that the Son of Man must suffer. This is crucial: Jesus is not presented as a simple military liberator.

Why this matters

If Jesus is Messiah, then his followers owe him loyalty. But because his kingship is shown through suffering service, Christian discipleship becomes shaped by humility, forgiveness and self-giving love rather than domination.

Son of God

The background includes Exodus 4:22, where Israel is called God’s son, and Psalm 2:7, where the king is addressed as God’s son. In the synoptics, the title appears at key moments:

• At Jesus’ baptism, the heavenly voice says, “You are my Son, the Beloved” in Mark 1:11.
• At the transfiguration, the voice says, “This is my Son, the Beloved; listen to him” in Mark 9:7.
• At the crucifixion, the centurion says, “Truly this man was God’s Son” in Mark 15:39.

The title therefore connects Jesus’ identity with divine approval, obedience and revelation. Importantly, the cross is not a failure of sonship; Mark presents it as the place where Jesus’ identity is paradoxically revealed.

Son of Man

The key Old Testament background is Daniel 7, where “one like a son of man” comes with the clouds of heaven and receives authority, glory and kingship from God. There is also a more ordinary background in Ezekiel, where “son of man” means a mortal human addressed by God.

In the synoptics, Son of Man sayings usually fall into three groups:

1. Present authority — the Son of Man has authority to forgive sins and is “lord even of the Sabbath” in Mark 2.
2. Suffering and death — the Son of Man must suffer, be rejected and be killed.
3. Future glory and judgement — the Son of Man will come in glory.

John’s “I am” sayings

John’s Gospel contains several sayings where Jesus says “I am…” followed by a symbol. The selected sayings for this topic are:

• “I am the bread of life” — John 6:35.
• “I am the light of the world” — John 8:12.
• “I am the good shepherd” — John 10:11.
• “I am the true vine” — John 15:1.

These are not random metaphors. They draw on Old Testament imagery and Jewish religious life.

Bread of life

This saying follows the feeding of the five thousand and recalls manna, the bread God gave Israel in the wilderness in Exodus. Jesus is presented as the one who gives true life, not merely physical food.

Light of the world

Light symbolises revelation, guidance, truth and salvation. It recalls creation, the pillar of fire in the wilderness, and Jewish associations of Torah and wisdom with light. In John, Jesus reveals God and exposes darkness.

Good shepherd

This draws on Psalm 23 and Ezekiel 34, where bad shepherds represent failed leaders and God promises to shepherd his people. Jesus as the good shepherd knows his sheep and lays down his life for them.

True vine

In the Old Testament, Israel is often described as God’s vine or vineyard, for example in Isaiah 5 and Psalm 80. In John 15, Jesus is the true vine and disciples are branches who must “abide” in him and bear fruit.

Brown and Dodd: two key scholars

Raymond E. Brown argues that Gospel titles often have layers of meaning. A title may begin with a Jewish background, be used during Jesus’ ministry, and then be deepened by the early Christian community after the resurrection. Brown is especially important for John because he sees the Fourth Gospel as the product of theological reflection within the Johannine community, not simply a transcript of Jesus’ exact words.

C. H. Dodd is famous for realised eschatology.

Dodd argued that John’s symbols are deeply rooted in Jewish Scripture and religious thought. For Dodd, John is not abandoning history but interpreting Jesus’ significance symbolically: eternal life is encountered now through response to Jesus.

Comparing them

Brown helps you avoid oversimplifying the titles. He would encourage you to ask how each title developed from Jewish expectation into Christian confession.

Dodd helps you see why John’s “I am” sayings are not decorative language. They present Jesus as the present fulfilment of God’s promises.

Implications for religious laws and codes of living

Different understandings of Jesus’ identity lead to different ethical emphases.

If Jesus is Messiah, Christians may understand him as the true king. This challenges loyalty to political power when it conflicts with God’s kingdom. However, because Jesus’ messiahship is suffering service, it supports non-violence, humility and care for the poor.

If Jesus is Son of God, Christian ethics becomes imitation of Jesus’ obedience and intimacy with the Father. The command to love God and neighbour is deepened by Jesus’ own example of forgiveness and self-giving.

If Jesus is Son of Man, Jesus has authority over religious practice. In Mark 2:27, “The Sabbath was made for humankind, and not humankind for the Sabbath.” This does not abolish law, but it suggests that religious law should serve mercy, restoration and human flourishing.

If Jesus is the bread, light, shepherd and vine, Christian life becomes a life of dependence on him. This influences worship, Eucharistic practice, pastoral care, moral guidance and the command to “bear fruit” in love.

These ideas also influence life beyond religious communities. Jesus as servant-king has shaped models of servant leadership. Jesus as good shepherd has influenced ideals of pastoral care, charity, education and protection of the vulnerable. Jesus’ challenge to legalism has also contributed to wider debates about whether laws should be applied rigidly or interpreted through compassion.

Evaluation: how convincing are these titles?

One strength of the Gospel titles is that they are rooted in Jewish Scripture. This gives continuity: Jesus is interpreted through Israel’s hopes, symbols and covenant language. Dodd supports this by showing that John’s imagery is not random Greek philosophy but deeply connected to Jewish tradition.

However, there is also diversity. “Messiah” in Mark is secretive and suffering; “Son of God” in John is much more explicit and exalted. Brown’s layered approach is helpful because it explains why the same title can carry different levels of meaning in different Gospel contexts.

A critical issue is whether these titles go back to Jesus himself or reflect later Christian belief. Brown would allow for development within the community, while still seeing that development as rooted in Jesus’ impact. Dodd would argue that symbolic interpretation can reveal truth even if it is not straightforward biography.

A balanced judgement is that the titles are best read both historically and theologically. Historically, they emerge from Jewish expectation and early Christian experience. Theologically, they present Jesus as the one who fulfils and transforms those expectations.
