The origins of Marxism, Bolshevism, and Cultural Marxism lie not in atheism and secularism, but in the occult, or more specifically, Gnosticism and Jewish kabbalah.
Kabbalah states that man doesn't just emanate from (the Jewish) God, but man is God's collaborator through the process of tikkun olam (literally, "repairing the world"). Through holy acts, the Jews have the power to trigger the coming of the messiah. In 1666, a kabbalist named Sabbatai Zevi declared himself the Jewish messiah and declared the only way to finish the tikkun - and make the world "one" - was to engage in acts of depravity. His successor, Jacob Frank, took this doctrine to Europe and radicalized it even more. The Frankists engaged in pure satanism before seemingly disappearing. What is not mentioned is, the Sabbatean-Frankist kabbalist doctrine simply took a new face in Marxism.
Marx was NOT an atheist but a Sabbatean-Frankist satanist. We know this based on the evidence. The Bolsheviks were overwhelmingly Jewish Sabbateans; Lenin was Jewish and based his dialectics on kabbalah, Trotsky's Permanent Revolution - which he theorized with Alexander Parvus (who served as the financial advisor to the Young Turks, all Sabbateans) - is based entirely on Jewish messianism as the messiah is supposed to spread communism to the entire world. Cultural Marxism is just modern-day Sabbateanism, as we know the most influential members of the Frankfurt School (Walter Benjamin and Theodor Adorno) were self-admitted Sabbateans. Benjamin even became a Marxist only after learning kabbalah from Gershom Scholem. Emperor Nicholas II (now considered a Saint) was also murdered by the Jewish soviets in a satanic ritual.
Writers such as Eric Voegelin also noted Marxism's distinct Gnostic character.
