Gregory Dolphin’s The Bible – Post Christianity! is at its most interesting when it moves away from the familiar argument over whether scripture is “true” and asks a different question: what practical work did early biblical texts perform for the communities that preserved them?

That shift appears most clearly in the chapter titled “Original Function of the Bible.” Here, Dolphin looks at the Torah not only as sacred literature but also as a social tool used by ancient communities to pass along law, health guidance, ritual expectations, collective memory, and a shared sense of identity.

Imagine a World Without Instant Information

Dolphin asks readers to picture ordinary life thousands of years ago. There was no broadcast news, public health website, phone alert, school system, or searchable database. Information moved through people. If a community needed to share warnings, rules, customs, or practical knowledge, it had to create dependable ways of remembering and repeating them.

That reality gives ancient assemblies a different meaning. Dolphin considers the synagogue, or its earlier social equivalents, as more than a place of prayer. A meeting place could also serve as a center where elders passed knowledge to families and community leaders.

In that setting, a body of respected teachings could do several jobs at once. It could define acceptable behavior, preserve stories about the group’s past, explain ritual obligations, and reinforce the bonds that helped a scattered or threatened population remain connected.

Scripture as a Community Memory

This is one of Dolphin’s more sympathetic readings of the early Bible. Although much of the manuscript strongly challenges later organized Christianity, he repeatedly suggests that the original Hebrew scriptures may have developed from a genuine need to preserve a people.

He imagines ancient Jewish elders facing migration, exile, conflict, outside influence, and the danger of cultural fragmentation. A shared body of stories and laws could help communities remember who they were even when political circumstances changed.

Seen this way, scripture becomes a form of cultural memory. Genealogies, covenants, stories of origins, laws, rituals, and warnings do more than describe belief. They give people a framework for continuity.

Dolphin believes this early function deserves to be separated from the later uses of the Bible that he criticizes. The same text can have one role in a vulnerable ancient community and a very different role centuries later inside a powerful religious institution.

Health, Cleanliness, and Everyday Survival

The manuscript pays particular attention to rules in Leviticus and related texts that concern food, cleanliness, contact with dead animals, disease, and periods of separation.

Modern readers may see some ancient rules as strange or excessively ritualized. Dolphin asks them to consider the practical conditions in which those rules developed. Long before germ theory, antibiotics, laboratories, or modern sanitation, communities still had to learn which behaviors seemed to reduce illness and which foods or conditions appeared dangerous.

He interprets some biblical cleanliness rules as early forms of health and safety guidance. Whether every rule had a practical medical benefit is not his main point. What matters is that the scripture preserved instructions about how people should live, eat, respond to contamination, and protect community boundaries.

That gives the Bible a social history beyond theology.

Crime, Punishment, and the Need for Order

Dolphin also compares biblical law with much older legal traditions such as the Code of Ur-Nammu and the Code of Hammurabi. These earlier law codes matter because they show that people were formalizing rules and punishments before the Torah reached its later written form.

Dolphin sees that context as including biblical law as part of a larger human effort to create order. Societies need methods of defining what behaviors are unacceptable, settling disputes, defending property, allocating responsibility, and deterring violence.

He does not romanticize biblical punishments. In fact, he is deeply disturbed by many passages involving execution, warfare, and collective punishment. Yet his analysis separates the existence of law from the claim that every law must have come directly from the Creator.

That distinction allows him to ask a practical historical question: what problems were these rules trying to solve for the people who lived under them?

Unity in a Time of Pressure

The book also treats religious unity as a survival mechanism. Dolphin believes that ancient Jewish communities faced pressures from neighboring cultures, foreign rulers, displacement, and competing religious practices. Common Lord, common law, and common covenant could serve to strengthen group identity when outside influences threatened to break up communities.

This reading may explain why obedience receives such emphasis in the early scriptures. Rules were not only private moral choices. They were connected to membership in a community.

Dolphin views the Torah as part law code, part historical memory, part religious framework, and part social glue. That mixture, in his view, is one reason the text endured.

When an Ancient Tool Outlives Its Original Job

The central question of the book returns here. If the Bible once helped ancient communities preserve identity, health knowledge, law, and social order, what happens when modern societies already perform those functions through other institutions?

Today, public health guidance comes from medical research. The government and courts have civil law. Education is organized by schools and universities. Historical information is stored in libraries, archives, museums, databases, and research institutions.

Dolphin argues that this change reduces the practical need for scripture as an authority over everyday life. A book that once carried several essential social functions no longer has to perform all of them.

That does not erase its historical importance. It changes its category.

A Different Way to Value the Bible

This may be one of the more nuanced ideas inside a book known for blunt criticism. Dolphin can reject the Bible as divine instruction while still valuing it as evidence of how people tried to survive, organize, remember, and explain their world.

That perspective makes the text worth studying even in the post-Christian future he imagines. Historians can examine it. Students can compare it with older laws and myths. Readers can explore how communities build identity and how stories change across generations.

The Bible, in this reading, does not become worthless when its authority is questioned. It becomes historical.

Gregory Dolphin’s argument therefore turns an apparent loss into a different form of relevance. Once readers stop asking the Bible to perform every role at once, they may be able to see more clearly what it reveals about the people who needed it first.

This approach also helps explain why Dolphin resists simple labels such as “fact” or “fiction.” A community document can contain memory, symbolism, exaggeration, practical wisdom, political interest, and genuine history at the same time. Ancient writers did not necessarily separate those categories the way modern readers do. A story could teach identity while preserving a distant event. A ritual could express faith while also reinforcing hygiene or social boundaries. A law could protect order while reflecting the values and power structures of its age. Dolphin’s reading invites readers to hold those possibilities together. Instead of asking whether the entire Bible must be accepted or rejected as one unit, he asks what different layers of the text may have been doing for real people in real historical circumstances then.

Historical context can preserve value without demanding obedience.
