On the shirt, the words TEACHING IS MY MINISTRY sit in bold capitals, an apple rests beside them, and beneath that the reference Romans 12:7 is printed in smaller type. That is the whole design: a claim, a fruit, a citation. I want to take it seriously as an artifact, because it is doing something more interesting than it first appears.

The apple is the oldest piece of visual shorthand in the school supply closet. In North American and Commonwealth primary-school imagery, the apple stands for the teacher as a figure of offering—the gift left on the desk, the fruit of knowledge, the one-room schoolhouse. It is a connotation in Barthes’s sense: a sign so worn that it no longer argues, it simply agrees. The apple does not say teaching is a ministry. It says teaching is teaching, in the softest possible register. It is the visual equivalent of a greeting card.

The citation is another matter. Romans 12:7, in the King James and most modern translations, sits inside Paul’s discussion of the body and its members: prophecy, ministry, teaching. The verse is usually rendered as something like if ministry, let us wait on our ministering; or he that teacheth, on teaching. The exact wording varies by translation, and I am not going to pretend the shirt settles which one it means. What matters for reading the object is that the reference is doing a different job from the apple. It is not decorative. It is an appeal to a specific text, in a specific register—scriptural, not sentimental.

So the shirt contains two registers that do not quite match. The apple is folk culture: warm, generic, child-facing. The citation is doctrinal: precise, adult, addressed to the wearer’s own sense of vocation. The phrase teaching is my ministry sits between them, and the interesting question is which one it belongs to. Read with the apple, it is a gentle affirmation—the teacher as caregiver. Read with the citation, it is a claim about the nature of the work: teaching as a calling with a scriptural warrant, not merely a job with a fruit on it.

This is where the shirt becomes useful as a piece of school culture rather than a piece of merchandise. Schools are full of objects that carry two registers at once, and the mismatch is usually the point. The house tie that is also a team colour. The plaque that is also a donor list. The hymn that is also a school song. In each case, the object works because it lets different people read different things into it without forcing them to agree. The apple lets the child see a teacher. The citation lets the teacher see a vocation. The shirt does not resolve the tension; it prints it.

I would not claim the shirt was designed with this in mind. The visual observation is plain: lettering, an apple, a printed reference. What I can say is that the combination is legible in a way that a plain slogan would not be. A shirt reading only TEACHING IS MY MINISTRY would be a statement. A shirt reading only Romans 12:7 would be a citation. Together, with the apple, they form a small argument about what kind of thing teaching is—and, by extension, what kind of thing a teacher is.

For school leaders, the artifact-reading question is worth borrowing. When you next walk past a staffroom noticeboard or a departing teacher’s gift, ask which register the object is speaking in. Is it addressing the child, the parent, the colleague, or the wearer? The apple speaks to the child. The citation speaks to the wearer. Most school artifacts try to speak to everyone at once and end up speaking to no one in particular. This one is unusually honest about its split audience.

The shirt is available as Teaching Is My Ministry Romans 12:7 Christian Teacher from Sunday Field. I have not worn it, and I am not going to pretend I have. What I have done is read it, which is the only thing the object asks of a culture worker.

Editorial note: this publication and Quirky Cotton Collective share an owner.

A small experiment for next week: take one object from your school’s staffroom—a mug, a badge, a signed card—and write down the two registers it carries. Then ask whether the people who made it knew which one they were speaking in. The answer is usually more revealing than the object itself.
