Although they will attempt to satisfy sola scriptura Actually the RCC does not need to find anything in the scripture to define its dogma.

i.e. Since the scripture is silent concerning purgatory the Church can rely on Tradition or the official statements of the Magesterium - these have equal weight with scripture.

Also any ex cathedra papal statements are binding upon all "the faithful".

 

In the Book of Hesitations. Near ...

"Cleanliness is next to godliness."
"God helps those that help themselves."

 

The most offensive are the Marian dogma which elevate (in affect) Jesus mother to a semi-divine status.

The 5th Marian dogma has been believed for decades but has not been proclaimed ex cathedra.
It is before the pope to promulgate it:

The Fifth Marian Dogma: Co-Redemptrix, Mediatrix of All Graces, and Advocate

 

It is ironic that it was "The Feast of the Assumption of the Blessed Virgin" that prevented me from ever becoming a Roman Catholic. I was converted from atheism to Christianity by a Catholic Charismatic Fellowship. I started reading the Bible and was up to the part where people were telling Jesus "your mother and brothers are outside" as the Church was preparing for the Feast of the Assumption of the Blessed Virgin (Mary). I may not know a lot about theology but I know the definition of "virgin" and "brothers" and the problem posed by that verse and the RCC beliefs on Mary's lifelong virginity. So reading through "A Catechism for Inquirers" didn't resolve the questions and the "Church Tradition" answer from the priest convinced me that I could never in good conscience accept the beliefs of the Roman Catholic Church so patently contradictory to the Apostolic writing. If the Bible can't be trusted to tell the truth, then we know NOTHING about Christ for sure. That was unacceptable to me.

Well, you have to tell me where in the 66 books of the bible that it lists the 66 books as canon? If you cannot tell me because it does not then how did you canonize 66 books. That would have to come from a source outside of the 66 books right? Then if that is the case couldn't one then say you also rely on tradition in determining which books are considered canon? It seems to me you can only account for 34 of the 39 books, and if you only mentioned those explicitly mentioned in the New Testament rather than an implied reference you may have to drop that number to 29.

 

Although Baptist are very reluctant to admit to "tradition" They/We do rely on outside sources to affirm the 66 books of the Bible.

Who Compiled the 66 Books of the Bible and When?

However, the Church of Rome goes far beyond that point and has in the opinion of many created many heretical dogma a few of which Yeshua1 has mentioned.

 

Prove it with historical evidence.
If you cannot prove with historical evidence what you say then it is a belief of faith.

 

So, what you are saying is that you are relying on Church Tradition to tell you which books were canon and not from the canon itself? Ok, if that is the case then I can show you where Church Traditions has upheld more than just the 66 books which you claim is the only canon.

 

I don't believe any of the NT books were in question with discussions of canon. The OT is another story.
