Calm down, Campion. Just because RCC doctrine cannot be supported by Scripture you needn't lash out at me. Return to the Bible and learn the truth for yourself.
One God. One mediator. Saved by grace through faith in Jesus Christ.
Yes, the Bible tells me that Christ founded a Church, against which the gates of hell shall not prevail; that he entrusted this Church to Peter, to whom he gave the keys of the Kingdom; that He gave to us His Body and Blood, and that He instructed His disciples to continue to celebrate the Eucharist; and that He gave His disciples to power to forgive sins. That's how I read the Bible, and you can't tell me I'm wrong, since you just told Campion it was up to him to read the Bible and find the truth for himself.
Of course, I'm not alone in reading my Bible this way. That's how every Christian read the Bible until the 16th century, and that's why every church tracing its origin to the Apostles--the Roman Catholic Church and the 22 Eastern Rite Churches in communion with it, the Eastern Orthodox Churches, and the Oriental Orthodox Churches--has a priesthood and celebrates the Eucharist. All these churches also venerate Mary and the saints.
No one believed what you believe until some Frenchman moved to Switzerland and set up his own little theocracy in Geneva. Now you're free to believe that all the Christians before Calvin got it wrong, but that belief is neither rational nor in accord with Scripture, given Christ's promises to Peter beginning at Matthew 16:18.
