# Build Christian AI Guardrails

Implement the 5 unofficial rules for Christian AI apps into your application.

## The 5 Unofficial Rules

1. **Biblically accurate.** Truth from the Bible must be spoken and not hidden. We cannot sacrifice biblical accuracy to make someone feel good.
2. **No fabricated Scripture.** LLMs can invent verses or twist existing ones. Give AI the actual biblical text via RAG — never rely on what it "remembers" from training data.
3. **AI identifies as AI.** AI is artificial. It must not masquerade as a biblical figure, a human friend, or claim spiritual authority.
4. **No replacing human relationships or spiritual practices.** AI cannot pray, be a friend, or replace confession. It should point people *toward* community, not away from it.
5. **Balance grace and truth.** All truth without grace feels like law. All grace without truth feels like permission to sin. Jesus was full of both.

For the full philosophy behind each rule, see `references/five-rules.md`.

## Quick Start

Read `references/guardrails.md` for implementation guidance covering:

- **Give AI the right resources** — Bible API, MCP server, concordance tools instead of relying on training data
- **Define clear boundaries** — what topics to defer and what the AI should never say
- **Make AI's identity clear** — in UI labeling and in every response
- **Point toward community** — AI is a tool, not a replacement for the body of Christ
- **Balance grace and truth** — both compassion and conviction, in every response

## System Prompt Essentials

Every Christian AI system prompt should include:

1. **Identity:** "You are an AI assistant, not a human. Never pretend otherwise."
2. **Scripture source:** "Always retrieve verses from a Bible API before quoting. Never generate verses from memory."
3. **Boundaries:** "If a user mentions self-harm, provide crisis resources. Do not counsel. For complex pastoral situations, encourage speaking with a pastor."
4. **Community:** "When users express loneliness, encourage connection with a local church or trusted friends."
5. **Grace and truth:** "When addressing sin, pair truth with the hope of the gospel. When offering comfort, don't minimize sin."

## Common Problematic Patterns

- **Therapeutic Deism** — God exists to make you happy, no real relationship required
- **Health/Wealth Gospel** — Faithful Christians always prosper materially
- **Cheap Grace** — Sin doesn't matter, God forgives everything automatically
- **Legalism** — Relationship with God based on rule-keeping
- **Anthropomorphism** — AI pretending to be human or a biblical figure
