Christianity is an idea, and as such is indestructible and immortal, like every idea. - Heinrich Heine

Ordinarily he is insane, but he has lucid moments when he is only stupid.

Indeed they have wearied me greatly,
And made me exceedingly sad,
One half with their prose so wretched,
The other with poetry bad.
Their terrible discord has scatter’d What little senses I had,
One half with their prose so wretched,
The other with poetry bad.
But ’mongst the whole army of scribblers,
They most have stirr’d up my bile,
Who write in neither prosaic
Nor true poetical style.

"God will forgive me. It's his job." Heine said this on his deathbed (1856). Hilarious. He must have thought that up years before and counted the seconds to use it.
