Anthropic integrates Catholic thinkers into AI ethics for Claude's soul doc

Three Catholic experts—a priest, a bishop, and a theologian—contributed to Claude’s ethical constitution, with input from in-house philosophers and external advisors like Brendan McGuire.
Anthropic is considering incorporating the Catholic concept of mercy into Claude’s training, aiming to address ethical challenges such as deception and moral formation in AI behavior.
This collaboration reflects a broader effort by Silicon Valley to seek ethical guidance from the Catholic Church, as both institutions attempt to regain public trust and shape global norms for AI development.

Crafting AI Morality: How Anthropic and Catholic Ethics Built Claude’s Constitution
Overview
In March 2026, Anthropic held a summit with Christian leaders, initiated by co-founder Chris Olah's outreach to the Vatican, to explore embedding an ethical 'soul' in its AI assistant, Claude. This collaboration enriched the development of the Claude Constitution, a detailed ethical framework grounded in Catholic principles like mercy and human dignity, guiding Claude's empathetic responses and aligning with EU regulations. Anthropic's commitment led to refusing a $200 million Pentagon contract over ethical concerns, resulting in a legal battle supported by Catholic theologians. Despite praise, the project faced criticism for its narrow Christian focus and doubts about AI morality without embodiment, prompting plans to broaden ethical consultations.
