I read that Karl Marx believed in Hegelian dialectics, but that Marx was an atheist who declared that “man is the highest being” for man, and, in his time, socialists believed only atheists could be true socialists. So, I’m surprised to read this theory that he was a Christian.
He was Jewish, then Christian, and then either became an atheist or a satanist.
Nothing in original post supports the idea that he was a Christian
