What is a system prompt?

Hidden instructions an app gives the model before your conversation starts. It sets tone, limits, and often theology.

Why it matters for Christians

The system prompt is where an app’s theology lives. Some Christian apps publish theirs.

What to do

Ask a Christian AI app to show its system prompt or a summary of it. Look for what it says about Scripture, speaking for God, and crisis help.
