The author presumes that his statements are indisputable, but the actual history does NOT back up his claims. He insists that the "authority of Rome" was always understood and implies it began WITH Peter and only continued to this day. This is provably false and easily seen by anyone who is willing to take off their prejudice-tinted glasses. In reality, it wasn't until the FOURTH century that Rome, and, consequently, the Bishop of Rome, saw the establishment of superiority, jurisdiction and power over all of Christendom. What we have today, was NOT what Jesus established with Peter, but the gradual mixing of state with church and the crowning of a monarchy over ALL.
There is no need to twist the authority of Rome into a historical mishap within Christianity because there IS no authority of Rome for all Christians. The ONLY authority we have is the chief shepherd, Jesus Christ, who promised to NEVER leave us or forsake us and the Holy Scriptures, where our rule of faith resides along with the indwelling Holy Spirit, who will lead us into all truth. We don't need a human ruler or king, we have the bridegroom and we are His bride.
For anyone interested in the TRUE origins of the Roman Papacy, this exhaustive work is extremely helpful History of the Papacy.
I looked at your source. Nearly every link I clicked was loaded with prejudicial statements and straw man arguments. Hardly persuasive.
