Outside of classical studies, papish notions regarding Greek and Latin were decidedly unpopular in Church of England era Britain (for obvious reasons!).
The real argument against Dickens at the time was more to do with his habit of serialising his novels in cheap newspapers. This then rendered his subject matter of choice - social commentary, fiscal egalitarianism, and empathy for the poor - a little too accessible for the comfort of the ruling classes.
He did so even in his own Newspaper 'Household Words' - which while championing the cause of the poor and working classes, did so by addressing itself almost exclusively to the middle classes!
"...We seek to bring to innumerable homes, from the stirring world around us, the knowledge of many social wonders, good and evil, that are not calculated to render any of us less ardently persevering in ourselves, less faithful in the progress of mankind, less thankful for the privilege of living in this summer-dawn of time." Charles Dickens
He started this with 'Hard Times' - a thinly veiled socialist critique against unbridled capitalism and immorality. It specifically targeted Edwin Chadwick, who helped design the Malthusian basis of the appalling Poor Law of 1834, but was more generally an attack on the Utilitarians of the time. Shaw described it as a "passionate revolt against the whole industrial order of the modern world".
