Generally yes. In most of the country you can decline to letter a specific message you believe is false or blasphemous, so long as you are refusing the words and not the customer, and you apply the same line to everyone who walks in. Write your policy down before the order comes, name the message you cannot make, and offer to sell the person anything else you sell.
What is actually happening
You are being handed a custom order you cannot fill in good conscience, and the order is often chosen precisely because you cannot fill it. The request is fishing for one of two things: a cake that carries your craft behind a message you deny, or a flat refusal that can be reported as a refusal of a person. Either outcome serves the story better than a quiet transaction would. What is missing from the conversation is the distinction that decides everything, between who is buying and what is being written.
The Manufactured Test Case · Rule 13. A broad disagreement gets collapsed into one small, personal, photographable moment with your name on it. You are frozen as the face of the whole dispute, and every answer is pre-sorted into affirm or bigot. The counter is to refuse the binary out loud: serve the person, decline the message, and keep both halves on the record.
What Scripture says
“Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God.” 1 Corinthians 10:31
What the book says · Chapter 7, The Anatomy of Modern Attacks on All Seven Mountains
“The tactic is Rule 13. The complex issue collapses into a binary moral test: either you affirm this specific action, or you are a bigot. The false dilemma frames anyone seeking a moderate solution as complicit in evil.”
From Rules for Radical Christians, quoted exactly.
What the law generally says
American law in this area generally turns on a distinction between the customer and the content. Public accommodation laws in many states require businesses open to the public to serve customers without regard to protected characteristics, and refusing a person is treated very differently from refusing a particular message. At the same time, free speech protections have generally been read to mean the government cannot compel someone to create expressive, custom work that carries a message he objects to, which is why a hand-lettered or specially designed item is often treated differently from an item already sitting in the case. Many states also have religious freedom statutes that add a further layer, and a few have none. Which of these applies to your shop, and how the line is drawn where you live, depends on your state, which is what Ask looks up.
The words to use
"I will gladly sell you anything in my case and bake you any cake in my catalog, and you are welcome in my shop. What I cannot do is letter words I believe are untrue about God, and I decline that wording for every customer who asks. Can you tell me the exact message you want written, so I can tell you today whether I am able to make it?"

Your move
- Get the order in writing. Ask for the exact wording, images, and date by email or text before you answer yes or no, and keep the thread.
- Write your own policy this week, before the next order. One page: you serve every customer, you decline a short list of messages regardless of who asks, and here is what you offer instead. Date it and keep it posted or on file.
- Answer in writing, in the words above. Name what you will do, name the one thing you will not, and ask them to confirm the wording.
- Offer a referral to another shop and record that you offered it.
- Ask a lawyer licensed in your state about your public accommodation rules before you rely on any of this. The line between a stock item and custom lettering is drawn differently from state to state.
- Document every order you have declined from every kind of customer. Consistency is your whole defense, and it only exists on paper.
- Ask for the requested message in the customer's own words, in writing. Verbal orders become whatever the other side remembers.
- Do not comment on the customer's life, identity, or household. The moment your refusal is about the person instead of the words, you have conceded the only point that mattered.
