Demons by Fyodor Dostoevsky

While not Catholic, Fyodor Dostoevsky (arguably the greatest Russian novelist) was an Orthodox Christian with a deep love for Jesus. His novels explore Christian themes including poverty, morality and faith while referencing the Church fathers and poetically pulling from the Orthodox liturgy. 

Inspired by the true story of a political murder that horrified Russians in 1869, Fyodor Dostoevsky conceived of Demons as a " novel-pamphlet" in which he would say everything about the plague of materialist ideology that he saw infecting his native land. What emerged was a prophetic and ferociously funny masterpiece of ideology and murder in pre-revolutionary Russia.
