Actually, it's the other way around. As a former Catholic (now protestant), I used to have the same misconception, but in reality, Catholicism is an inherently socialist (if not communist) faith because it was invented by socialist Roman emperor Constantine (by watering down most of the Christian morals to get Romans to convert), it was used as a tool for controlling the masses (during feudalist Europe), and a key part of Catholicism's morals involves volunteering & charity, which are both pointless from a capitalist's perspective because it's far more logical to give jobs to the poor folks so they can earn money for themselves, plus, it rewards the ones who are willing to work the hardest.
I don't even like to consider Catholicism a Christian faith because it involves worshipping a pope, which violates the First Commandment, and Jesus Himself was an anarcho-capitalist who hated the Roman authorities controlling the Jews. I know what you might be thinking, "No, the pope is just a religious leader who helps guide us to God", but the idea that the pope is infallible pretty much constitutes as worship.
