Not only that. The seeds of Greek polytheism were already planted in the Torah by the influence of Alexander the Great's armies long before the first five books of Moses were adopted into the religious canon of the Christian bible. When the Hebrew text was translated into Greek, it is likely even more of that influence crept in. Later books about Apostles, Saints, and other Holy personages, as well as the mistranslation of the import of the Holy Trinity eventually became the equivalent of polytheistic religious cannon as well. Opposing such influence would have been viewed as heresy or sacrilege, and punished severely. Monotheism became polytheism all too easily by a church leadership craving the devotion of its followers as if they themselves spoke and wrote only the inspired wisdom of deities themselves. And this doesn't sound like a conspiracy to you? "An effort to explain some event or practice by reference to the machinations of powerful people, who attempt to conceal their role (at least until their aims are accomplished)." Wrapping delivery and import of your sermons in the scripture your church hierarchy has crafted to support the status of religious leadership would easily qualify. The motives are clearly conspiratorial in the same mode as any crime syndicate. The sale of indulgences was enough for Martin Luther to see through the conspiracy, and call the Vatican on the carpet for them. It isn't as though at least a few people didn't see through the conspiracy of lies. Concealing pedophilia in the church is another easy one that fits the description. Do you really need any more?
