There is nothing so fleeting as the memory of benefits received. ”

I know no man who feels deeper disgust than I do at the ambition, avarice, and profligacy of the priesthood, as well because every one of these vices is odious in itself, as because each of them separately and all of them together are utterly abhorrent in men making profession of a life dedicated to God. ”
