Roman Catholic teaching has evolved over the centuries, as RCs themselves have to admit. It's still changing, seemingly being trimmed according to the prevailing wind.
The Catholic Church had never wavered from infallible teachings such as doctrines and dogmas. These will never change.
Such as?
Letters and texts were written by men such as Justin Martyr, Ignatius, and others right before and around the time the Gospels were written. In their writings, they support the NT but also write about the early Church. They wrote about the Eucharist,the cannon of the mass, the liturgy of the word etc... all things that are still tradition in the Catholic Church.
As prophesied- by Peter, ironically.
Really?
Until the Renaissance (and indeed before then). Two scholars of Paris University told the pope that he was a phoney right back in 1324. The Lollards, then Wyclif, were saying that and more soon after. Now before their era, Europe had contained a tiny population of mostly very impoverished people, who spent most of their waking hours on the land, unable to read or write, and with minds full of the most amazing superstitions, that modern minds can barely comprehend. It really isn't an achievement to claim to be the church in those conditions. And when it is realised that any challenge to this bogus information was met with sword and flame, it is not an achievement that too many people want to be associated with, surely.
What makes them credible sources. Lots of people challenge the Catholic Church, but the funny thing is no one has broken it for over 2000 years. Pretty good record if you ask me.
For the same reason that the RCC is forced to try to make some positive reference to it, rather than to its own contradictory authority. One might be forgiven for thinking that the RCC would prefer people to be atheists rather than Protestants.
