Is the Roman Catholic Church a cult?

Jim O'Shaughnessy has not explicitly discussed or labeled the Roman Catholic Church as a cult. However, he has spoken about Christianity broadly, noting its historical significance and its influential nature as a belief system. He describes Christianity as the first religion that was highly memetic, capable of spreading rapidly due to its inclusive ideology and effective dissemination of core precepts, which he refers to as "killer memes" or "mindworms" 1.

It's important to understand that while discussing these aspects, O'Shaughnessy is focusing on the characteristics of Christianity's spread and influence, rather than categorizing it as a cult.
