The Roman Catholic church hasn't consistently taught "one single uniform teaching" Jesus commanded His disciples to teach for a very long time - if ever. We have ample proof that many of the dogmas and doctrines the modern RCC follows were never heard of either in Scripture or by the early Christian church. You expect everyone to just take it on faith - like the Roman Catholic "faithful" are expected to - that whatever the magesterium in power at any particular time decides is "de fide" must be what all Christians have to believe? Prove the Apostles ever taught "purgatory", or "indulgences" to get people out of it. Show where any Apostle ever taught Mary was born without a sin nature or never had other children with her husband, Joseph. Demonstrate from Scripture where ANY Apostle taught there was to be ONE, singular Pope of the universal church and that ALL had to be in subjection to him. Know what? You can't. I think you know that and we certainly do.
Your reasoning makes no sense because again you fall into the error of saying that many Catholic beliefs like dogmas etc., aren’t recorded in Scripture You take as your single source Scripture (even though Scripture itself informs that there were many things Christ said and did that were not recorded, and yet the books in Scripture did not fall from the skies but its selection was based on the received oral tradition, which helped the early Church Fathers decide which books should be in the Bible and which were not, such as where the so-called Gnostic gospels that were excluded. These were decisions of the profoundest authority. i.e. what constitutes the sacred written text.
Then you purport to dispute this very authority of the Catholic Church to insure that there be one single teaching because by “your” reading of Scripture you may offer “your” own “authoritative” version.
This is precisely what leads to multifarious interpretations often at diametrical odds to one another. Think Jim Jones, David Koresh, Rev. Jeremiah Wright, Rev. Moon, Rev. Jimmy Swaggart, Joe Osteens etc.
Now, strange, isn’t it that leading Protestant and Episcopalian theologians and scholars who have written several books and taught theology and history of Scripture in major Protestant-oriented colleges and university, have upon their further ongoing study and research now ditched their former writings, analyses, and beliefs, including quite recently, the pastor of Sweden’s preeminent Protestant congregation and converted to Catholicism. These theologians, quite apart from having the courage of their convictions, did not have to use religion to gain personal profits and amass fortunes like the “pastors” named above.
We need to get back to where this discussion started. There is one Church, with one single authority given by Christ to Peter and his successors, to teach one truth to be the mustard seed that becomes the one universal Church in all corners of the Globe. This Church is sustained by the litany of its saints and the blood of martyrs. It’s theological foundations have been tested through two millennia confronting the early heresies. Therefore it is tragic that the evil of Protestantism has, in the words of the great English essayist Hillaire Belloc, spawned a “cluster of heresies” that we now have every Tom, Dick, and Harry right down to Rev. Jeremiah Wright or Rev. Billy Graham or Rev. David Koresh spouting “their” own interpretation of Scripture to say nothing of Jehovah’s Witnesses and the Mormons. These birds of a feather that stick together have one thing in common, they all deny the reality of the Eucharist and the most elevated form of worship, the Mass.
