The Authority of St Mark’s Gospel

What does it mean to give Mark’s Gospel authority?

St Mark’s Gospel is one of the four accounts of Jesus’ life and teaching in the New Testament. For Christians, it is more than information about the past: it can guide what they believe about Jesus and how they live today. Authority means the recognised right or power to guide beliefs, decisions or behaviour.

There are several questions to separate. Is Mark historically reliable about Jesus’ life? Does it communicate a message from God? Does its teaching offer good guidance for living? Someone might accept its ethical value without believing that every event happened exactly as described. Another person might regard it as a trustworthy ancient account without accepting that it has divine authority.

Why Christians regard the Gospel as authoritative

Christians believe that Jesus reveals God. The Incarnation is the belief that God became human in Jesus. If Jesus is God revealed in human form, an account preserving his message has an authority that an ordinary teacher’s biography would not have. Mark’s portrayal of Jesus’ teaching and miracles therefore helps Christians understand who Jesus is and why they should follow him.

Christians also believe that the Gospel writers were inspired by the Holy Spirit. Divine inspiration means that God guided the writing of scripture. However, Christians differ over what this means for the words on the page.

Some understand the Gospel as the Word of God in a very direct sense, believing that the Holy Spirit dictated its words. They therefore place strong trust in the accuracy and authority of what it records. Others believe that God inspired a human author who selected, arranged and interpreted accounts of Jesus. On this view, recognising the writer’s historical setting and purpose helps readers understand God’s message rather than undermining it.

These approaches can produce different interpretations within Christianity. A Christian who reads an account literally may treat it as a direct record of an event. Another may place greater emphasis on the religious meaning that Mark communicates. Both may still give the Gospel authority over their faith and conduct.

Can an ancient account be trusted?

Mark is generally dated to around 65–70 CE and is widely regarded as the earliest of the four Gospels. Its closeness in time to Jesus’ life is a reason for taking it seriously as historical evidence. Some scholars argue that it draws on eyewitness memories, especially those of Jesus’ disciples. It also preserves some Aramaic words, the language Jesus spoke, within a Gospel written in Greek. These features can support the argument that it retains early traditions about Jesus.

However, it was written several decades after the events it describes. Stories had been passed on orally, and memories can lose details or differ between witnesses. Mark also wrote to communicate Christian beliefs, not simply to produce a neutral record of events.

A sceptical reader may therefore question whether every detail is accurate. A Christian response is that a religious purpose does not automatically make an account false, and that divine inspiration could work through human memories and traditions. Neither its early date nor its religious purpose settles the question by itself: the disagreement concerns how much weight to give each consideration.

Challenges from contemporary secular authority

In contemporary British society, people also turn to scientific knowledge, historical enquiry and reasoned ethical discussion for guidance. These are secular sources of authority when their authority does not depend on belief in God or scripture.

Science challenges an appeal to the Gospel when a religious claim is accepted simply because it appears in a sacred text. A humanist approach asks for evidence and uses the scientific method to understand the natural world. Humanists reject supernatural explanations, so they would not accept Mark’s miracle accounts as proof of Jesus’ divine power merely because Mark records them.

Christians may respond that, if God exists and created the natural world, God could act within it. From that viewpoint, the usual regularities studied by science do not by themselves show that divine action is impossible. However, this response explains why a Christian considers miracles possible; it does not independently prove that a particular miracle happened. The detailed interpretation of individual miracle stories is a separate question from whether Mark should have authority overall.

Historical enquiry raises a different challenge: an account should be assessed through its date, origin, purpose and evidence, rather than automatically trusted because it is scripture. Christians can accept these methods while also believing that the Gospel communicates religious truth. Faith and historical enquiry are therefore not necessarily complete opposites.

Ethical value without divine authority

Humanists base ethical decisions on reason, empathy and concern for the welfare of humans and other sentient animals. For them, a teaching is not right simply because a religious text contains it. It should be assessed by its reasons and its effects on others.

This does not mean that Jesus’ example has no relevance to non-religious people. In Mark 10:45, Jesus says that the Son of Man came ‘not to be served but to serve’. A Christian can see this as an authoritative example from the Son of God, shaping service to others in personal and community life. A humanist can value the emphasis on service because helping others promotes welfare, without accepting the verse’s claim about Jesus giving his life as a ransom.

The same teaching can therefore influence people for different reasons. For the Christian, its authority may come from who Jesus is. For the humanist, its value depends on whether it withstands ethical reasoning. Atheism means not believing in God or gods; it does not mean rejecting every religious teaching, nor does every atheist share the same moral outlook.

Reaching a justified judgement

An evaluation needs to identify what kind of authority is being discussed. If the question concerns Christian faith, belief in Jesus’ divinity and the Holy Spirit’s inspiration provides strong reasons for Christians to follow Mark. If the question concerns whether everyone should accept its claims about the past, secular readers can reasonably ask for evidence beyond an appeal to divine inspiration.

One defensible conclusion is that Mark has religious authority for Christians, while its historical claims remain open to critical enquiry and its ethical teaching can have value beyond Christianity. A stronger claim—that it should be the final authority for everyone—would need reasons that also address people who do not share Christian beliefs. The quality of the conclusion depends on explaining why the arguments support it, not simply stating a personal preference.

Grounds for Christian authority

• Jesus: belief in the Incarnation gives his message divine authority.
• Inspiration: Christians believe the Holy Spirit guided the Gospel’s writing.
• Different interpretations: some understand its words as directly dictated; others recognise an inspired human author’s interpretation and historical context.

Historical reliability

• Mark was written around 65–70 CE, generally regarded as the earliest Gospel.
