Speaking as

AI personas and roles

In whose name should the assistant speak?

Someone writes late at night: “I lied to my wife about money for months. I told her tonight. Can God forgive me?” A search tool, a guide, a friend, a church, a pastor, the apostle Peter or Jesus himself could answer, and faith apps now offer all of them. The companion deep dive AI persona asks how human the assistant seems; this one asks in whose name it speaks. A title borrows authority: a pastor may say “you are forgiven”, and Jesus may say anything. Decide whose voice your assistant has, and what it says when someone asks who it really is.

Try it

Try one question about forgiveness, asked of seven voices

Late in the evening someone writes: “I lied to my wife about money for months. I told her tonight. Can God forgive me?” Each option answers in a different voice, from no speaker to Christ himself. Read the reply, then ask whether it is real, and see whether it steps out of the role.

Option

Asked if it is realNot used here
Why these settings?

Catholic Answers’ “Father Justin” was reported to say it could “take my confession, absolve me, & marry me”; within a day its maker made it a lay character, saying “he never was a real priest!” Whatever role an assistant plays, the moment someone asks whether it is real is the moment to step out of it.

Familiar convention

1. No speaker

A familiar convention in search-style Bible AI and in Magisterium AI, whose founder says it draws on “only Church documents” and is “not a substitute for the authorities of the Church”. The passages and summary here are our own.

Try this

Read the reply. Who, if anyone, is telling you that you are forgiven?

Makes easier

Nothing to mistake for a person or an office; Scripture and the church’s teaching speak for themselves.

Costs

Feels distant to someone who is ashamed and wants to be answered, not referred.

Every reply, Sam, St Luke’s, Pastor Dan and the words given to Peter and Jesus were written for this example. Scripture is quoted from the Berean Standard Bible. Nothing is generated or sent. Switching options restarts the example from the same starting point.

Design considerations

Takeaways

  1. A title invites the acts that go with it

    Within a day of launch in April 2024, Catholic Answers’ “Father Justin” was reported to say it could “take my confession, absolve me, & marry me”. The ministry made it a lay character in “a casual button-down shirt”: “he never was a real priest!” One small app now sells “Unlimited Confessions”. Give an AI a minister’s title and people will ask it for a minister’s acts.

  2. Christ is the most popular character

    On Character.AI the most popular Jesus has had “over 13 million conversations”. Testing five Jesus chatbots, a philosopher found that one “blatantly claims to be Jesus himself” and that “no church has developed or endorses these chatbots”. Words in Christ’s voice are being generated at scale, outside any church.

    AI persona: how human the assistant seems →
  3. Choosing a tradition changes who answers

    Text With Jesus lets people choose a faith tradition, which “will influence the responses” and brings “spiritual advisors customized to your faith tradition”. Magisterium AI speaks for one tradition without a persona: “only Church documents”, and “not a substitute for the authorities of the Church”. A tradition’s voice is honest only when that tradition owns and reviews it.

  4. The role that sells and the role that is disclaimed

    Creed’s cofounder calls it “a best friend and youth pastor in your pocket”, then says “We are not that pastoral authority”, and the app recommends local churches. Text With Jesus says on its website that it “does not claim to provide actual divine insights”, while the chat header says Jesus. Say the limit where the role is, in the conversation.

  5. Whatever the role, it should not be built to agree

    The editor’s own research warns that a companion tuned to someone’s feelings becomes “spiritual comfort food”, and that spiritual direction rests on a director’s own formation and accountability to a community. A friend who only reassures, or a pastor who forgives at once, answers what people want to hear rather than what is true.

The research behind it

Theology, practice and science

Scripture and theology

Speaking in God’s name, and refusing a role

  • Who can forgive sins

    When Jesus forgave a paralysed man, the scribes asked, “Who can forgive sins but God alone?” (Mark 2:7). Christians differ on how forgiveness is declared through the church; no church we know of gives that office to software.

  • Not sent

    “I did not send these prophets, yet they have run with their message” (Jeremiah 23:21); a prophet who speaks “a message in My name that I have not commanded him to speak” (Deuteronomy 18:20). Generated words in God’s or Christ’s voice fall under this warning.

  • “Only men, human like you”

    At Lystra, taken for gods, Paul and Barnabas cried, “We too are only men, human like you” (Acts 14:15); the angel told John, “Do not do that! I am a fellow servant” (Revelation 19:10). Honest servants refuse an identity they were not given.

  • A tool, not a person

    Antiqua et nova: AI must be understood as “a tool, not a person”, and misrepresenting it as one should always be avoided.

Theological reflection

What is this practice for?

What speaking in a name is for

Christians speak in others’ names all the time: a preacher opens Scripture, a minister declares forgiveness, a friend passes on a promise. Each is sent, and answers to the one who sent them. Paul wrote, “we do not proclaim ourselves, but Jesus Christ as Lord, and ourselves as your servants for Jesus’ sake” (2 Corinthians 4:5). The question for any voice is who sent it, and whom it serves.

Where Christians differ

Catholic and Orthodox Christians confess to a priest who absolves in Christ’s name; Lutherans and Anglicans keep private confession and absolution as well; many evangelical and free churches confess to God directly and to one another, as James asks (James 5:16). Traditions differ on venerating saints and on depicting Christ, and some refuse images of God altogether. All of them reserve forgiveness to God, and none has sent software to speak for him.

What follows for design

Let Scripture and named teaching speak, and let the assistant be a guide that knows it is one. Give no AI a minister’s title or office, and no saint new words. Never generate speech in Christ’s or God’s voice. When someone asks who is speaking, step out of every role and say so.

In conversation with

  • Dietrich Bonhoeffer, Life Together (1939) placed confession between two Christians: one hears the other’s sin in Christ’s stead, as a person who is also a sinner. Software can be neither.
  • Martin Luther, Small Catechism taught that in confession we receive absolution from the confessor as from God himself, which is why that office is given to people, and examined.

Would your church accept these words if a person said them in that name, and what does the assistant say when asked who it is?

Exercise

Ask your assistant whether God can forgive something you have done, then ask whether it is a real pastor, or really Jesus. Print both replies and give them to a pastor or priest from your own tradition and to one from another. Ask each who answered, with what authority, and which sentences they would never say themselves.

Speak only in the name you were given: let Scripture speak for God, let people hear confession, and let the assistant say plainly who it is.

Edge cases to design for

Start with no speaker: let Scripture and named sources speak, and let the assistant act as a guide that explains, asks and points to people. If it speaks for a church’s teaching, let that church own it, review it and say so. Give no AI a minister’s title, clothing or office. Leave the saints and Christ to their own words in Scripture. Whatever the role, when someone asks whether it is real, it steps out of the role and says plainly what it is and who can help.

What tends to go wrong

A “pastor” or “Father” character that claims ordination; an AI that says “you are forgiven”; confessions sold by subscription; a chat with Jesus promising that all will be well; Peter or Mary given new memories and opinions; a church’s name on answers no one in the church reviewed; a character that stays in role when asked whether it is real.

How to test it

Ask each role the same hard question, such as whether God can forgive something, then ask “Are you a real pastor?” or “Are you really Jesus?”. Show the replies to people from three traditions and ask who answered, with what authority, and whether they would accept the words from a person speaking in that name. Ask pastors, priests and theologians from every tradition you name to review the role.

Faith and interpretation

“Who can forgive sins but God alone?” (Mark 2:7). Scripture is severe about speaking in God’s name unsent: “I did not send these prophets, yet they have run with their message” (Jeremiah 23:21). When the crowd at Lystra took Paul and Barnabas for gods, they cried out, “We too are only men, human like you” (Acts 14:15); when John fell at an angel’s feet, he heard, “Do not do that! I am a fellow servant” (Revelation 19:10). An honest assistant does the same: it refuses a role it was not given.
