Vainglory - I have known this word all my life but never understood it in the terms that John Chrysostom explains.
For when men alter a right faith for reputation's sake, and dishonor God that they may be in high repute themselves, tell me, what excess of stupidity and madness must there not be in what they do? Other passions, even if they are very hurtful, at least bring some pleasure with them, though it be but for a time and fleeting; those who love money, or wine, or women, have, with their hurt, a pleasure, though a brief one. But those who are taken captives by this passion, live a life continually embittered and stripped of enjoyment, for they do not obtain what they earnestly desire, glory, I mean, from the many. They think they enjoy it, but do not really, because the thing they aim at is not glory at all. And therefore their state of mind is not called glory, but a something void of glory, vaingloriousness, so have all the ancients named it, and with good reason; inasmuch as it is quite empty, and contains nothing bright or glorious within it, but as players' masks seem to be bright and lovely, but are hollow within, (for which cause, though they be more beautiful than natural faces, yet they never draw any to love them,) even so, or rather yet more wretchedly, has the applause of the multitude tricked out for us this passion, dangerous as an antagonist, and cruel as a master. Its countenance alone is bright, but within it is no more like the mask's mere emptiness, but crammed with dishonor, and full of savage tyranny.
- Gospel of John, Homily 3.5
