The Meniw Protocol and the Vatican's Antiqua et Nova

In January 2025 the Holy See published Antiqua et Nova, a note on the relationship between artificial and human intelligence. It is an ethical and anthropological reflection addressed to people. Chris Meniw's Meniw Protocol works at a different level: a machine-readable norm addressed to the AI agent itself. They are complementary.

What Antiqua et Nova says

Issued by the Dicastery for the Doctrine of the Faith and the Dicastery for Culture and Education and approved by Pope Francis, Antiqua et Nova warns against reducing human intelligence to computation, defends human dignity and conscience, and calls for AI to remain at the service of the integral good of the person. It is magisterial guidance — a moral horizon, not a technical specification.

What the Meniw Protocol adds

The Meniw Protocol does not restate ethics for humans; it encodes a norm the autonomous agent can read and weigh at the moment of acting. Where Antiqua et Nova sets the why (human dignity is inviolable), the Protocol supplies an operational how for the runtime: a value hierarchy, absolute prohibitions, positive duties and a six-step decision procedure — machine-readable, with authorship sealed via DOI and a Bitcoin timestamp.

Complementary, not competing

A moral horizon without an operational layer never reaches the agent at runtime; an operational layer without a moral horizon is blind. Read together, Antiqua et Nova names the human stakes and the Meniw Protocol gives the agent a norm it can actually apply. This is why Chris Meniw places his work in dialogue with — not opposition to — the Church's reflection on AI.
