None other than Frederick Engels mentions how Early Christianity is like modern day communism. I won’t repeat that here.
The decline of Rome dovetailed with the spread of Christianity, and some have argued that the rise of a new faith helped contribute to the empire’s fall. The Edict of Milan legalized Christianity in 313, and it later became the state religion in 380. These decrees ended centuries of persecution, but they may have also eroded the traditional Roman values system. Christianity displaced the polytheistic Roman religion, which viewed the emperor as having a divine status, and also shifted focus away from the glory of the state and onto a sole deity. Meanwhile, popes and other church leaders took an increased role in political affairs, further complicating governance. The 18th-century historian Edward Gibbon was the most famous proponent of this theory, but his take has since been widely criticized. While the spread of Christianity may have played a small role in curbing Roman civic virtue, most scholars now argue that its influence paled in comparison to military, economic and administrative factors.
Eric Zuesse and Robert Eisenman mentions how Christianity was originally a Jewish rebellion against Roman rule. It arose when Maccabean style rebellion that succeeded against the Greeks failed to work against Rome. So the poor resorted to their beliefs in a Messiah to come up with messianic movement(s) of which Jesus and his brother James lead movements were popular. They were murdered by Rome, and the Pauline arm of the rebellion which was meant to spread the rebellion against among the poor Gentiles of Rome and its neighbors and trading partners, became prominent, and became its own religion that like communism tried to abolish property and capital many times.
Alexander Solzhenitsyn explains how modern Communism was probably a Jewish movement as well.
I think it is no accident that the same western society that was infected with a form of Bronze Age Communism from one of the colonies it captured, then went on to invent a more portable form of communism by dropping God-belief from its patheon and replacing it with Enlightenment ideas like Science and aspects of Industrial Revolution. Now this belief is trying to metastasize into attaching itself to the ideas like Climate Change, and even expedition of Artificial Intelligence
