The Revolt of the Angels by Anatole France

"The new superstition spread at first over Syria and Africa; it won over the seaports where the filthy rabble swarm, and, penetrating into Italy, infected at first the courtesans and the slaves, and then made rapid progress among the middle classes of the towns. But for a long while the country-side remained undisturbed. As in the past, the villagers consecrated a pine tree to Diana, and sprinkled it every year with the blood of a young boar; they propitiated their Lares with the sacrifice of a sow, and offered to Bacchus -- benefactor of mankind -- a kid of dazzling whiteness, or if they were too poor for this, at least they had a little wine and a little flour from the vineyard and from the fields for their household gods. We had taught them that it sufficed to approach the altar with clean hands, and that the gods rejoiced over a modest offering.

"Nevertheless, the reign of Iahveh proclaimed its advent in a hundred places by its extravagances. The Christians burnt books, overthrew temples, set fire to the towns, and carried on their ravages as far as the deserts. There, thousands of unhappy beings, turning their fury against themselves, lacerated their sides with points of steel. And from the whole earth the sighs of voluntary victims rose up to God like songs of praise.
