Faith and AI  ·  By John Moelker, a pastor who builds AI

Should Christians use ChatGPT?

I am in an unusual spot to answer this. I build AI products for a living, including tools that serve churches, and I have been a pastor for fifteen years. So I am neither afraid of ChatGPT nor dazzled by it. I know what it is on the inside, and I know what it can never be. Here is the honest, practical answer, with the line drawn where it actually belongs.

Why ChatGPT is allowed: a tool is not a sin

Scripture never treats a tool as good or evil in itself. People made tools from very early in the story; Genesis records the first metalworkers and instrument makers only a few generations in (Genesis 4:21-22). When God wanted the tabernacle built, He filled a craftsman with skill to do it (Exodus 31:3-5). The same kind of skill, in other hands, built idols. The tool did not decide. The heart did.

So the New Testament does not give us a list of permitted tools. It gives us a wider test: "whether you eat or drink, or whatever you do, do all to the glory of God" (1 Corinthians 10:31), and the companion line for anything this powerful, "all things are lawful for me, but not all things are helpful" (1 Corinthians 6:12). The question was never whether ChatGPT is permitted. It is what you are doing with it, and what it is doing to you.

Good and faithful ways to use it

Most ordinary uses are no more spiritually fraught than using a calculator or a search engine. These are genuinely good uses:

• Learning quickly: the background of a Bible book, the meaning of a word, the history behind an idea.
• Getting unstuck at work or at home: organizing your thoughts, drafting an email, untangling an overwhelming week.
• Preparing for a hard conversation by thinking through what you want to say, then saying it yourself, face to face.
• Serving: planning a meal train, writing a clear announcement, preparing discussion questions for a group.
• Accessibility: helping someone read, write, or communicate who otherwise could not.

Used this way, ChatGPT is a bridge. It carries you faster to the thing you were already trying to do, and then it gets out of the way. If that is how you are using it, you can put the guilt down.

Where to be careful

There are real cautions, and as the engineer I can tell you exactly where they live.

It can be confidently wrong

ChatGPT does not look facts up; it predicts the next likely words. Most of the time that is correct, but sometimes it produces something false in the same calm, authoritative voice, including inventing Bible verses that do not exist. So verify anything that matters, and check every verse against a real Bible. The Bereans were commended for examining even the apostle Paul's preaching against Scripture (Acts 17:11). Do the same with a chatbot.

It carries a worldview

It was trained on a vast slice of the internet, so it reflects the assumptions of that material, which are not always Christian ones. It is not neutral on questions of meaning, morality, and the human person. Read it the way you would read a clever stranger with no particular allegiance to Christ: useful, but weighed.

It must not become a substitute

This is the one I care about most.

ChatGPT is a bridge to people and to God, never a replacement for them.

It is always available, endlessly patient, and never asks anything of you, which is exactly what makes it a tempting counterfeit for the harder, realer things. Do not let it become the voice you trust about your soul instead of your pastor and your church. Do not let it pray in your place; "your Father knows what you need before you ask him" (Matthew 6:7-8), and your honest, clumsy prayer is worth more than a polished one a machine produced. Do not let it do the slow work of study and obedience that God uses to form you.

A simple test you can use

When you are unsure about a particular use, ask one question: does this point me toward God and toward real people, or does it quietly try to stand in their place? If it sends you into Scripture, into prayer, into your work, and back to your people, use it freely. If it is becoming the place you go instead of those things, stop. That instinct, trained over time, is most of what discernment is.

So, should Christians use ChatGPT? Yes. Use it with wisdom, not fear and not worship. Let it carry you faster toward the real things, and never let it become a substitute for them. I wrote a fuller answer to the conscience question in is it a sin to use AI, and a plain explanation of how it actually works in what a large language model actually is.

Frequently asked questions

Should Christians use ChatGPT?

Yes, with a clear conscience. It is a morally neutral tool. The question is how you use it: let it serve your faith and work, and never let it replace Scripture, prayer, the Holy Spirit, or your church.

Is ChatGPT safe for Christians?

It is safe with discernment. It reflects its training data, so it can be biased or wrong, and it sometimes invents facts and verses. Treat it as a fast but fallible assistant, verify what matters, and do not treat it as an authority on your soul.

Can Christians use ChatGPT for Bible study or prayer?

For Bible study, yes, as a research assistant, if you verify every verse and do your own reading. For prayer, only as a starting structure if you are stuck; then close it and pray in your own words. Never let it pray for you.

Is using ChatGPT cheating?

Not when you use it to research, brainstorm, or sharpen your own work. It becomes dishonest when you pass its writing off as your own where honesty is owed. The line is honesty and ownership, not the tool.
