If Paul wants the Greeks to whom he's writing to behave, he can't throw the law back at them ("Thou shalt not be obscene"), and he's already told them that they are to be disposed to that
which is above, not on the earth. So how does he tell them to "Behave!" without actually telling them? He does so by writing his behavioral instructions to them in the middle voice—a special form of the Greek verb that is neither active nor passive. Here's how that works. (More details coming up on MZTV 488.)
