Kazantzakis was the type of "Christian" (Orthodox, even) who simped for communism so much so that he not only turned a blind eye to the first hand accounts of Panait Istrati, a subhuman atheist and until then also a simp for communism, but among the first to describe its horrors and failures, with the proverbial "But where is the omelette?", but actually advised him against it and renounced him, along with all the socialist hipster French faggot elites of the period, from Henri Barbusse to Romain Rolland.
These are very similar to the "Christians" (Orthodox, even) of today. It's all memes and personal interpretations to fit & justify whatever worldview you already have, molded into you by your entourage. Read it lightly, as sweetened fairy-tales of the likes of Dostoevsky.
