There is a religious aspect to teaching, even when the subject matter is not religious and the school is non-sectarian. This is because what is taught ought to be, at the very least, true.
Since truth is determined by God (consider these verses) the teaching profession is necessarily in the service of God — whether or not individual teachers acknowledge it. That is why James could write in this Sunday's lesson, "Not many of you should become teachers" adding that "for you know that we who teach will be judged with greater strictness."
