Of the Apostles, only Matthew and John wrote Gospels, and we know this fact only by tradition, because neither author identifies himself by Name. Yes, the canon consists of writings attributed to Apostles or to those close to them. But nowhere in these writing is there a list or even a divine command that someone produce such works.
Now lets look at some of the teachings of the RCC that come from those books that contain errors. Praying to the dead is one of them. Jesus or the Apostles didnt teach that. Jesus wouldnt even let the apostles talk to Moses and Elijah and God condemned the talking to the dead in the Old Testament.
So you go right ahead and listen to an organization that uses books that have errors in them and relies on stories handed down through 2000 years that were not taught by the apostles and some that didnt even start until at least 400 years after the apostles. Im going to stay as close to what Jesus and the apostles taught and trust that the Holy Spirit will keep me from falling for those errors that the RCC and others teach. K?
