Eladar,
Correct me if I am wrong but I think it was you who said, 'First of all, the Catholic Church is the only church who can trace her history back to Christ Himself.' {I believe this was taken from page 1 toward the bottom of the page}.
No scholarly person would believe this lie hatched from Satan's diabolical spirit. I am sure many a catechumen and novice has been taught this as child. You need to study the Greek in Matthew 16:18 and other passages about who the Bible says is the Rock. A concordance will help you find Rock.
'Roman Catholicism teaches that the Roman Catholic Church was established by Christ through Peter as the first visible head. The authority was the authority that God gave to Christ and that Christ in turn gave to the church. Non-Catholics would establish the beginning of the Roman Catholic Church in A.D. 590 with Gregory I "who consolidated the power of the bishopric in Rome and started that church on a new course.' Dr. Loraine Boettner, "Roman Catholicism" Philadelphia: Presbyterian & Reformed, 1962) p. 126; cf. A.M. Renwick, The Story of the Church (London: InterVarsity, 1958), p. 64. This was first read by me in Dr. Paul Enns book, "The Moody Handbook of Theology," Moody Press, Chicago, p. 529. Three major theologians agree with the above statements, plus this is my view also.
The Apostle Paul told us that an apostate church would surface soon after the apostles died. When we tuck in all the spurious doctrines of the Roman Catholic Church in a neat box, she well fits the designation.
The Apostle Paul warned the Colossian Church 2:8 that men would add to the church's revelation, the Bible, their philosophies and traditions. By your own admission you claim that your church goes back to the Apostolate. The philosophy and traditions of men clearly were not in the Protestant Church because we were not born as a church until 486 years ago.
Therefore, Paul was talking about your deliquent, apostate church, no offence intended.
Who do you think Paul meant in Colossians 2:8?
