The RCC was born under Constantine in the 4th century. James, the brother of Jesus,(yes that's right, Mary had more children) led the church formed by Jesus and Peter was an Apostle, just like the rest of them. There is no popes, no Cardinals, no Nuns, in the church Jesus started. Why would Rome be the center of the church and NOT Jerusalem?
In every verse of the Bible, a stone or a rock refers to Jesus and you misunderstood Mat 16 thinking a man would run Christs church. The same thing will happen in the Last Days when the RCC will mistake a man as Jesus returned. He will be the Antichrist.
If you won't do the research on the RCC beginnings, I can't help you. If you read the Revelation verses you can't help but see that the RCC is the only religion that fits the description. What church is on every Continent on the Planet? Who has killed more Christians than anyone on the planet? If you don't have eyes to see, you will never see it unless the scales fall off. It will be just as Paul was blinded but was given sight when Jesus revealed Himself to Him. The Vatican has Satanic rooms under ground. They have a Satanic pagan obelisk in front of St. Peter's church. There is another 10,000 words I could write on what's wrong with the RCC, but you have to do the research yourself. Just look up "Madonna and child" and you will see it dates back to Babylon. You even use the same verbiage and imagery as Babylon. Satan is more than a liar, he is a counterfeiter. That's why the rainbow has been stolen from God and given to sodomites.
Speaking of sodomites,..................
Take the "Satanic obelisk". It's in the Vatican because it originally stood in Nero's circus, where the first martyrs of the Roman church died. You know what us awful Papists carved into it? "Christus vincit, Christus regnat, Christus imperat" ... "Christ conquers, Christ rules, Christ reigns". Does that sound Satanic to you?
Practically everything you object to about Catholicism can be shown to exist long before Constantine. What DIDN'T exist until 70 years or so AFTER Constantine was uniform agreement on the canon of the NT. That's right: your Bible is ultimately a product of the "corrupt" post-Constantine church. BTW, even some SDAs now admit that Sunday worship can be traced to the Apostolic age.
