## Why it matters for Christians

A persona of Jesus is not Jesus. A persona of a pastor is not your pastor.

## What to do

Do not pray to or take spiritual direction from an AI playing Jesus, a saint, or someone who has died. If you use a persona for study, such as “answer as a first-century historian,” remember it is a costume, not a witness.
