Hugo never lost his antipathy towards the Roman Catholic Church, due largely to what he saw as the Church's indifference to the plight of the working class under the oppression of the monarchy; and perhaps also due to the frequency with which Hugo's work appeared on the Pope's list of "proscribed books" (Hugo counted 740 attacks on "Les Misérables" in the Catholic press). On the deaths of his sons Charles and François-Victor, he insisted that they be buried without crucifix or priest, and in his will made the same stipulation about his own death and funeral. However, although Hugo believed Catholic dogma to be outdated and dying, he never directly attacked the institution itself.
