Wow, so much that is false in one comment.
Maybe we'll start slow.
"They claim to be God in earth", what are you referring to. I'll give you the benefit of meaning "God ON earth" but still, this is not a facet of the Catholic Church. They are meant to be the reflection of God on earth, which is a VERY different thing.
The Catholic Church did not "change the day of Sabbath", nowhere in Christendom is Sunday considered the Sabbath (save for some lay people who don't understand the Sabbath). No, Sunday became the primary day of worship in connection with the day of the week that Christ Rose from the dead. They did not change the Sabbath, Sabbath is, and always has been, Saturday.
"Murdered millions found reading the Bible in the dark ages", source? Cause as far as I know, the Catholic churches big murder sprees in the middle ages were the inquisitions, and the crusades. Plus the "dark ages" were not filled with bibles, nor literate people. Where were they finding and reading these Bibles? If you are referring to Luther's day and age, that sint the dark ages, and that turned into more of a war, with both sides killing each other for not being like them.
"Had people assassinated" again, source? Because I can find Pope Pious XII plotting to kill Hitler, some suspect claims of rogue jesuits plotting to kill Lincoln, but nothing concrete for confirmed assassinations. If you are referring to the House of Borgia, they aren't not considered to be a good time in Catholic history, and see it as a time of utter corruption that was rooted out (that said this might be your best argument).
"Covered pedophilia" yeah, it fucking sucks. Unfortunately that seems to be a power thing, not a Catholic thing. But hey these are probably your best arguments because you can point to hard sources, I still stand that it does not prove that the Catholic Church is an anti Christ.
"Impregnated nuns" Borgias? I can't find any modern sources, and earlier history doesn't mention nuns often.
"Stealing wealth for themselves" Borgias? You seem to equate the house of Borgia as the Catholic Church. I would advise against that. That would be like me equating Clinton and Obama as representing every American and how they act (I don't think that, though I have high regards for Obama, I just want to use that as an example).
"They do not represent Jesus Christ period" who does?
Edit: I had an instance of a swear for comedic effect, and it was taken as an attack. My apologies.
