No. Catholicism, like the majority of the world's religions, simply has a strong tradition aside from their main holy scripture which they believe has explanatory, cultural, historical and spiritual value. Look at most other religions and you will see a similar example.
Regardless, I think in just about every major world religion (and probably a few of the minor ones), you can find examples of the older "version" of that religion with an extensive body of documents and a newer "version" that is unhappy with the way things are and so defines itself by denouncing oral and written traditions. Catholicism, Hinduism and Orthodox Judaism are examples of the former whilst Protestantism (and more recently the "Born Again" movement), Buddhism and Jainism and finally Reform Judaism are examples of the latter. And several of those went on to define their own traditions as well.
Yes, i agree with you, But i say that these changes were made by the Will of the flesh, that is was not Divine Revelation that invoked the changes in creed. Methodist, Pentacostal, Lutherans, Orthodox.... they all have different ideas and translations of scripture that they belive to be "the way it is" and it was, in every case, one man somehwere that decided this and was crafty enough in speech to sway people to his side. alot branching off the Roman Catholic Church. What's kind of funny is, that Organization of Christ's church is clearly described and defined in the New Testament. Jesus - 12 apostles - The Seventy. All of the Apostles and organizational Leaders were all killed off. But there were still those who believed on him and followed what teachings they still had, and organized thier own church according to thier will in an attempt to continue traditions, but had no official "Priesthood" to Act in god's name.
There has been no Church to follow that same structure of Christ's Original Church for 1800 Years. Untill Joseph Smith revealed the B.o.M. (now i'm not prostelyting, just comparing.) and foudned the LDS church. (and when revelation was given to stop certain practices because they were illegal, they got split off from just like the Catholic church did with all the offshoots. but that was the will of the flesh and not divine revelation for those offshoots LDS and Catholic)
My point in being, that IF any religion actually DID read and study the bible and see the church structure of Christ's Church, would it not make sense to follow that same pattern?
Edit: I'm going to make a thread based on this reply seeign as it's starting to get a little off-topic on my end.
