"Lord defend us!" I can imagine some (genuinely!) pious soul intoning. "You see how, even here, Satan uses even the tiny things of the world to impinge upon the sacred things You've given us."
On the other hand, might not that little bird's have been a voice from a certain other corner of "the world?" A realm of which Satan knows little, and understands less? A realm in which - unlike certain places in the human heart - he's always had the most devilish time securing even the tiniest foothold?
