From "Star Trek: Deep Space Nine: Tears of the Prophets (#6.26)"
The Prophets don't see me as a Starfleet captain. They see me as their Emissary.
That's the problem, isn't it? For the past six years you've tried to be both. And up to now I've been patient. I have indulged you, I have gone out on a limb for you many times. But this is it. You've got to make a decision. You are either the Emissary or a Starfleet captain. You can't be both.
